…………..when seen on the base or the heel of early 20th century American-made soda and beer bottles, in most cases indicates production by the American Bottle Company, at their Streator, Illinois plant location. (The “S” stands for Streator). The number usually precedes the letter, but in some cases the order may be reversed, with the number positioned to the right of the letter. These marks were used by ABCO at least during the 1916-1923 period, and evidence from bottle collectors indicate these date code markings may have been used as early as 1905 (when American Bottle Company was incorporated), all the way up to at least 1931, possibly even 1933 in a very few cases. Owens Bottle Company, which purchased the six plants of the American Bottle Company in 1916, continued the operation of only two of those ABCO plants (their Newark, OH & Streator, IL locations) under the American Bottle Company name until 1929, and used this type of marking on many of their bottles. Also, see “AB”, “A.B.CO.” and “17N” marks. For more background information and context on these bottles, please see this article written by archeologist/researcher Bill Lockhart (along with input from several other researchers).

……………. see full article on webpage here: Star Works/Company, New Albany, IN (1869-c.1879). In 1879, W. C. DePauw acquired entire ownership, and the factory then (or soon afterward) became known as DePauw’s American Plate Works, with the window / fruit jar division being called “W. C. DePauw Company” in city directories. The operation produced fruit jars (some are marked “W C D” on the base), and continued to operate until the Panic of 1893 caused the plant to shut down. Sporadic attempts to revive the works failed. This star marking is usually quite boldly embossed, has five points, and has a characteristic “look” that is different from several other types of stars seen on the bases of bottles from the 19th century. Probably the most well-known bottle variant found with this bold, heavy star mark on the base is a “squat quart” Cream Ale bottle made for Alonzo Templeton of Louisville, Kentucky in the very late 1860s and early 1870s. It is found in shades of amber, including orange amber, red amber, and a dark olive amber that looks almost like black in reflected light. Note: this is only one type of star. There are other types of stars seen on a wide variety of bottles that have no connection to the firm in New Albany, Indiana. A star on the base of certain bottles found mainly on the west coast might be attributed to Pacific Works, San Francisco, CA (see entry below). Also, see “3 Rivers” and “N next to or within a star” marks. There are also many cases in which bottles exhibit a star in the design or on the base which has nothing to do with the glassmaker, usually being a decorative device or a mold identifier. See “W.C.D.” and “X” entries, also please see all other “Star” entries on this page).

………. Alexander & David H. Chambers, Pittsburgh, Pennsylvania (c. 1852–c.1889). This was one of the most prolific companies in Pittsburgh during the mid-to-late 1800s. Huge quantities of bottles, flasks, and fruit jars were made, as well as window (which was ostensibly their primary product). Many local, regional, and nationally distributed sodas, ales, mineral waters, beers, bitters, tonics, and other types of products were packaged in bottles made by A&DHC. Most commonly, bottles with this mark seem to date from the 1870s and 1880s, but the mark was evidently in use from around 1860. Most bottles made by A & D H C in the earlier years (1840s and 1850s) evidently did not bear a manufacturer’s mark.

………………………….. A & J Manufacturing Company, Binghamton, New York. A&J specialized in manufacturing kitchen-related products such as mixers and egg beaters, and evidently the company had a business arrangement with Hazel Atlas Co. to mark certain accompanying products. The most commonly seen item marked with those initials is a pitcher or large measuring cup that also served as the bottom container for a food mixer. That pitcher was patented in 1923. A & J was acquired by EKCO, of Chicago, IL, in 1929. Since those pitchers (in a medium green typical of Hazel Atlas during the Depression era) are fairly common and must have been made in large numbers, it is probable that many were made after 1929, continuing to carry the “A & J” marking after EKCO acquired the company.

The bottles thus marked are colorless (or nearly so) and were almost certainly made by an unidentified glassmaker in England. They generally appear to date from the 1880s to the 1920s period. Trade cards were published illustrating the product and the bottle, and many variations of those trade cards are known – bearing addresses of cities around the US, mainly Eastern and Midwestern locations, on the reverse of the cards.

Also, a flask marked “Guaranteed Full Pint” posted on the antique-bottles.net discussion site bears “A & W” on the bottom, but that bottle appears to date from sometime in the period of 1895-1915 and likely stands for a later, unrelated and unidentified company.

Chicago, Illinois (office – 1905-1916); Toledo, Ohio (office – 1916-1929). plants were located at Streator, Illinois; Newark, Ohio; Belleville, Illinois; Massillon, Ohio & Wooster, Ohio. The American Bottle Company was purchased by Owens Bottle Machine Company in 1916 (with some of the plants being closed soon afterwards) but the Streator and Newark plants continued to operate under the American Bottle Co. name until 1929, when they became part of the merger that resulted in Owens-Illinois Company . (For Streator and Newark plant marks from 1916 to 1929, see “17N” and “16S” entries). Most, if not all, of the “AB”, “AB CO.” and “A.B.CO.” marked bottles are believed to date between 1905 and 1916. However, it is possible that some bottles with these markings might date between 1916 and 1929, but, if so, could only have been made at either the Streator or Newark plants.

………………. Adolphus Busch Manufacturing Company, plants at Belleville, Illinois (1886-c.1905) and St. Louis, MO (c.1893 – c. 1921). The Belleville factory became part of American Bottle Company c. 1905. (See AB (connected ) and A.B.CO. marks). ABGMCO produced huge quantities of beer bottles for Anheuser-Busch Brewing Association, but also beer bottles for other brewers and bottlers, as well as other types of containers including soda bottles and wax sealer style fruit jars. Without the original label intact, it would be difficult or impossible to be sure what brand of beer any particular bottle marked “A.B.G.M.CO.” originally contained. The lettering is typically arranged in a circular fashion, and usually accompanied by a mold letter/number combo placed in the center of the base. In some cases, the lettering appears to be “A. B. C. M. Co.” as the mold engraver frequently made the letter “G” look more like a “C”. Also see “A B G CO”, which was evidently used in the first few years of operation.

The first actually produced at Jonesboro under the new ownership was in the fall of 1957. The period of use of this particular mark is unclear, although it seems to have been used at least as far back as the very late 1980s and is still in use today [2024]. The mark is seen currently on grocery store shelves, for instance on packer jars containing certain brands of jellies, preserves and other food products. AGCC apparently specializes in “packer ware” for a large variety of food products sold at retail as well as canning jars for consumers’ home use. An earlier mark used by Arkansas was “g A c” (larger capital “A” with smaller upper case “G” and “C” placed to left and right). See that mark under the “gAc” entry on Page Three .

……………….. Alexander H. Kerr & Company (see Kerr Manufacturing Corporation ), making plants at Altoona, Kansas (1909-1912); Sand Springs, Oklahoma (1912-1992); later plants at Huntington, West Virginia (1933-1983); Santa Ana, California (1943-1992); Plainfield, Illinois (1964-1996) and several other locations. Business offices were located in Los Angeles after 1919. The exact name of the Kerr company changed several times over the years. The first use of the AHK trademark by Kerr, according to U.S. Patent & Trademark Office records, was stated to have been on September 9, 1944. This mark was most commonly used on packer ware (jars, jugs and bottles for pre-packaged products sold at retail – such as mayonnaise, pickles, applesauce, coffee, etc.) as opposed to fruit jars for home canning. Most of the packer ware containers do not carry date codes so they can be harder to date than beverage bottles, such as soda and beer bottles which normally do bear date codes. The earliest beverage bottles I’ve seen with the AHK mark have “72” date codes. Julian Toulouse ( Bottle Makers and their Marks, page 44) mentions the 1944 date, but also stated (in the same book) on page 544 that the AHK mark was used “since 1968” which seems contradictory. I believe he may have given that date in reference to when the first beverage bottles were marked with the AHK trademark? Or when Kerr acquired the former Whitall Tatum/Armstrong plant in Millville, New Jersey? For more detailed background info on Kerr and various marks used, see this article by Bill Lockhart et al: Kerr – SHA.org

…………………….. Airko Manufacturing Company, Clermont, Florida. This mark (often hard to read, and at a glance may be mistaken for Anko, Arko, Aiko or Aiiko) is seen on at least two styles of clear shakers. The most common type features horizontal raised rings or ribs encircling the shaker, similar in appearance to the Depression-era “Manhattan” pattern made by Anchor Hocking. Those shakers apparently date from the 1930s-1950s and their actual manufacture is attributed to Hazel Atlas Company and/or Anchor Hocking (if you know which is correct, please let me know!). They were advertised as featuring a special design that helped keep the salt dry and free-flowing in humid weather.

But the bottles marked “ ” are from a later, unrelated company that bore a similar name. An iron-pontiled blob-top soda bottle in cobalt blue, and two types of historical flasks with the bust of Washington on them are lettered with this company name across the front, and those bottles evidently date between 1847 and 1851. HOWEVER, the great majority of flasks with this inscription found today are modern reproductions dating after the 1930s, with most having been produced up into the 1960s or 1970s or even later. If you have a flask with the marking “ ”, it is best to assume it is a repro until proven otherwise!

This mark was registered as a trademark in 1947 with “first use” stated as June 23, 1932 – but on pressed tableware such as tumblers, goblets, coasters, sherbet glasses, etc. Manufacturer of a wide line of tableware over the years, Barlett-Collins later became a subsidiary of the Lancaster Colony Corporation (owner of Indiana Company after 1957). Bartlett-Collins produced items such as jars, mugs, canisters and votive candle holders under the brand name “Indiana ”.

The “ ” mark was also used by Burlington Works, Hamilton, Ontario, Canada (1875-1909) on the face of their “Burlington” fruit jars. A Moxie soda bottle variant with a crown lip carries the mark, and in that case would have been made by an unidentified factory some time after 1892 (the year the “crown” style lip was introduced). “ ” is also reported on the heel of a light green crown lip Anheuser-Busch Brewing Association beer bottle that appears to date from the 1910s or 1920s.

………………………… Unknown meaning (Seen on base of amber quart “blob lip” beer bottle, c. 1885, shown here in pic). The bottle is an “Apollinaris” or “Champagne” style (profile) bottle. “PAT 85” is referring to William Painter’s patent for his so-called “Baltimore Loop” seal, issued on September 29, 1885 (Patent number 327,099). The “Pat 85” embossing appears on the bases of many bottles (both beer and soda) made by a number of companies in the mid and late 1880s. Although it has been proposed by some researchers that this mark is merely a mold-cutting error for “D.O.C.” (see that entry), I am doubtful and believe that this actually does stand for an obscure, short-lived company, brewer, or beverage bottling company with those corresponding initials. ( NOTE : Some local Louisville-area bottle collectors believe the “ ” stands for BOCHART (F. & P. Bochart), a bottling company based in New Albany, Indiana (c. 1890-1907). This may be correct, however, no definitive proof has been so far discovered, and it is extremely unusual, if not unknown, for a base marking to consist of the first few letters of a surname. But, the fact that the only known examples of this bottle were found within less than 30 miles of New Albany is evidence this COULD be Correct!!). The embossed lettering is very strong and bold on this bottle. Note: If anyone comes across a bottle with the “ ” mark on the base, I would love to hear from you (see the Contact Information page ). If the location of finds can be noted, this may give us more clues pointing to the area (city, state) where these bottles were most likely made and used. Currently I know of only two examples of the bottle, both found in southern Indiana towns near Louisville, KY. There are surely others out there hiding in collections, tucked away in attics, or just waiting to be dug!

A reader of this page, Dawn High, who was trying to find the user of one of these “bird logos” as it appeared on the base of an olive oil bottle/cruet, introduced me to this (formerly unidentified) mark. Now, thanks to Joel B. Miller, more info can now be published revealing the user of these marks! Two “older” logos (both with a more “horizontal” look) were used from approximately 1980 to 2014. Their third bird logo (with a somewhat more “vertically oriented” design) is currently in use, introduced on new molds in 2014. Phoenix Packaging contracts with many customers around the world to have special container designs produced to their specifications. Many different bottles and jars have been made, as well as packaging in other mediums such as ceramic, plastic, wood, metal, etc. Several dozen manufacturers have been involved at some time over the last few decades, including well-known container firms such as O-I and Verallia.

Undated
glass
………………………. trademark seen on base of “Gordon’s Dry Gin” liquor bottles. Gordon’s Gin was introduced in 1769 by Alexander Gordon who established a distillery in London. The product was originally sold in pottery/stoneware/ceramic bottles, but bottles were introduced in about 1904. (Some sources state the transition started as early as 1898). The boar (wild pig) design varies somewhat from one bottle to another, since hundreds of different bottle molds have been produced over many decades – made by many companies, and a number of different mold-cutters (mold engravers) have produced the designs since 1904. The raised design is sometimes poorly delineated, crude or unclear, and has occasionally been likened to the representation of a wolf, wild dog, crocodile, peccary, dragon, wild hare, or other untamed beast. The boar is usually pictured with an open mouth, facing left, showing bared, dangerous-looking teeth -the teeth more prominently visible on some bottles than on others. The photo above shows the emblem on the base of a colorless Gordon’s Gin bottle base shard – heavily scratched and worn. Whole or partial bottle bases with this trademark are sometimes found as “beach ” or “sea ”. Gordon’s Gin bottles have been found in clear, off-clear, light aqua, light green and shades of darker green. Most of the green bottles were/are produced in Great Britain, and clear or off-clear bottles have been typically produced outside Europe. A distillery was established in Linden, New Jersey in about 1934, and some bottles bear that city name on them. I’ve seen bottles made by Brockway (B in a circle), Owens-Illinois (Diamond/oval/I, and later, I inside an O) and Diamond Company, Royersford, PA (plain Diamond logo), although there are likely bottles out there made by many other glassmakers. (Most of the Gordon’s Gin bottles made in the first several decades of container packaging were produced in England or Scotland).

………………………. Bromo-Seltzer was an extremely popular drug, in the form of a powder, introduced by Isaac Emerson circa 1888. The great majority of Bromo-Seltzer bottles were made in cobalt blue, although a few are also found in light aqua. This is one of the most common antique bottles found today- and they were made in the millions by half a dozen or more glassmakers – in at least six different sizes, and in many types and subtypes, both mouthblown and machine-made. Some examples have been dug in other shades of blue such as a dark “ink” or “midnight” blue. There is some uncertainty about some of the “off-color” blue and green shades – some are unquestionably irradiated (“nuked”) bottles – but others may be authentic and “as found” – actually dug in dumps and privies.

[Update 2/11/2023] – archeologist Nina Peck reported a similar bottle also found on Guam – during excavation for utility lines – and she was able to contact a retired professor and manufacturing industry researcher named Mr. Shoji, (庄司太一) of Tokyo, who relayed that the mark almost certainly stands for the Kirin Brewery Company’s Tonda bottle manufacturing plant, located in Suotonda-cho, Shinnanyo, Shunan City, Yamaguchi Prefecture, Japan. According to one website (kirinholdings.com), the Tonda bottle plant was started in 1938. That bottle factory was sold to KYC Corporation in 1992.

………………….. This was actually a hair dressing made with Coconut Oil, promoted as a product guaranteed to give the hair a more luxurious, healthy appearance. Contrary to what some collectors might assume upon finding a bottle with this embossing, the product did not contain cocaine (unlike some of the products being sold in the mid and late 1800s that did indeed contain that ingredient). First sold in 1857 by Joseph Burnett of Southborough, Massachusetts, it was a popular product for many years and was still available into the early 20th century. Several variations of the bottles exist. The glassmaker is uncertain, but it is probable that one or more bottle companies located within or near the Boston area manufactured these bottles. This webpage from the Southborough Historical Society has some information on Joseph Burnett: Joseph Burnett Chronological History .

……………….. On containers, sometimes this might be simply a mold identifier, but in many cases the letter probably stands for a specific company. A capital letter “ ” is seen on the bottom of quite a few older handmade bottles of various types (that generally date from the . 1870s-1890s) and there is no conclusive evidence to indicate exactly who made them. One fairly strong possibility is Cunningham & Company of Pittsburgh (see & Co marks on this page). Other possibilities include Clyde Works, Clyde, New York; Canton Company, Canton, Ohio; and Cohansey Mfg. Company, Bridgeton, New Jersey. See this article by Bill Lockhart and the Bottle Research Group (pages 621-623) in which some “ ” bottles are discussed: Cunningham Family Holdings – SHA.org . I have been told (by longtime bottle digger and collector Dave Beeler) that a lot of bottles of various kinds with just a “ ” on the bottom have been dug in the St. Louis, MO area over the years, and he believes the mark may stand for John K. Cummings (proprietor of the St. Louis Works for a number of years) – Cummings was involved with that factory beginning in 1861 and lasting until its apparent closure in 1888. Although I can’t say whether Dave is correct or not, he certainly brings up an interesting question. Several notable bottles are found with a “ ” on them. Just three examples: The GIX-25 type scroll or violin flask (found in a number of colors including aquas and greens) bears the letter “ ” on the front. The scroll flask type is generally of Midwestern origin. Some collectors believe this particular flask originated from Pittsburgh (in particular, Cunningham’s works). Another pictorial flask, lettered “The Great Western” across the front, and catalogued as GX-30 (in McKearin’s historical flask charts) is marked with a “ ” on the base. It’s provenance is unknown, although believed to date from sometime in the 1865-1875 period. Note: there was a factory in St. Louis, . 1856 named “Western Company” that failed after a short time, and also a much later, unrelated glassworks named “ Great Western Works “ (1874- .1887). A clear nursing bottle marked “St. L. G. W.” across the front (the lettering probably standing for St. Louis Works) is marked with a “ ” on the base. Whether there is any connection between those three bottles is unknown.

These initials have been confirmed on the lower side of a light green handblown cylindrical pickle bottle or “Chow Chow” food bottle that looks exactly like the bottles described above that bear “C B / M” or similar lettering on their bases (see above entry). The “ ” mark has also been verified on the bottom of an applied-lip ale or beer bottle (made from a 3-piece mold) which appears to date from the 1870-1900 time period. That bottle, in sun-colored amethyst, was found recently in a secluded high desert setting in the southwest. Julian Toulouse (BM&TM, 1971, page 114) stated that containers made for Crosse & Blackwell were made by a number of companies in Great Britain including Davey & Moore; Cannington Shaw & Company; Kilner Bros.

Clevenger Brothers specialized in producing handblown flasks and other glassware made in the tradition of the early factories of New Jersey. Some examples can be very difficult to distinguish from the originals, although there are always subtle differences upon close examination, especially concerning the exact appearance of the base pontil mark. Most of their earlier bottles and flasks were unmarked, although a few pieces were marked with a small “CB” on the bottom, beginning in 1955. After 1966, all of their glassware was marked with “C B” although the lettering is typically larger and bolder.

The C.G.Co. initials which are known on the bread tray from approximately 1885 (and may be on other items in the “Polar Bear” pattern as well) were attributed to Crystal Co. by Ruth Webb Lee in her groundbreaking reference work “Early American Pressed ” (1931 and later editions) from a personal conversation she had with an elderly knowledgeable Pittsburgh-area glassblower. Crystal Company made mostly pressed tableware items (usually classed under “Early American Pattern ”, known to collectors as simply EAPG) and was not a producer of blown commercial containers, so this mark is virtually certain to be UNRELATED to the “C.G.Co.” seen commonly on beer bottles.

……………Cristalerias Cattorini Hermanos, Buenos Aires, Argentina, South America. (1952-to date). This mark is most frequently seen in the US on the base or heel of imported emerald green (“forest green”) beverage bottles, often marked “WATER” and/or “JUICE”. These containers were often saved and re-used as refrigerator bottles. I believe most, of not all, of those bottles were made in the 1960s or very early 1970s, but some may date later. The trademark is evidently still in use and appears on the Emhart punt marks database.

Initials are seen on bases of mouthblown black (very dark olive green or olive amber) ale and wine bottles, usually made in three-part molds. These bottles were evidently exported far and wide around the world as they have occasionally been found in such places as the Panama Canal, the Caribbean region, Australia, New Zealand, Canada and Asia, as well as the UK and the U.S. These initials had been a mystery for many years, but with help from the BRG (Bottle Research Group) and in particular from recent in-depth research by BRG member Bob Brown, this is virtually certain to be the correct user of the initials. The earliest reference found so far is from 1847 – The Journals of the House of Commons , Volume 102, page 184, in which an entry is found referring to “Carson, Warren and Company, Bottle Manufacturers” and David Carson and Timothy Warren as partners in that business firm. The physical factory itself was called the “Milton Works”. The operation might have been under other business names at times during the period, but in any case it apparently failed in or about 1879. One example of a very rare black bottle has also been recorded (evidently found in Australia), marked with the full embossing “CARSON WARREN & CO. GLASGOW / MANUFACTURERS” on the base. Assuming that this works was in operation for at least 32 years, and made countless bottles over that period of time, it seems apparent that the great, great majority of its bottle production was unmarked. There is little doubt that many of the “generic” black bottles exported from Great Britain during the mid-19th century could be unmarked products of Carson, Warren & Company.

In some cases this mark is rather crudely drawn and thus it might be difficult to recognize what it’s supposed to represent. The figure below the castle may be mistakenly thought to be a lower-case letter “g”, and although it does bear a resemblance to that letter, it is meant to be the representation of a Key.

……………… Consolidated Fruit Jar Company, New Brunswick, New Jersey, with main business offices in New York City, New York (1871-c. 1924 or later). Consolidated did not make their own jars, but had a number of factories manufacture them bearing the company logo. Consolidated was primarily a manufacturer / distributor of so-called “fruit jar trimmings”, i.e. zinc lids, bands and gaskets for the jars, as well as other sheet metal and tin ware items including watering can sprinkler heads, oiling cans and assorted kitchenware. Factories that are known to have made jars for CFJCO included: Clyde Works (Clyde, NY); A. & D. H. Chambers, Pittsburgh, PA); Whitney Works (Glassboro, NJ); Illinois Company (Alton, IL); Poughkeepsie Works (Poughkeepsie, NY) and likely others. Some of the CFJCo monogram jars are also marked with the name or initials of the glassmaker. But many are not – and in those cases the factory is not known – with absolute certainty, anyway. It is quite possible that a number of unidentified factories in the East and Midwest made many of the jars, but there are (probably) no extant records to prove they did so. The CFJCo monogram was placed on fruit jars, zinc lids, and jar liners (inserts) beginning about December of 1877. That trademark (#5,947) was officially registered by the US Patent Office on April 23, 1878. The trademark document indicates “first use” of the monogram had occurred approximately four months before April 3, 1878, the day the application for the trademark was made. Assuming that information was correct, the first jars with the CFJCo trademark were probably made in early December of 1877. There is uncertainty on how late jars marked with that monogram were manufactured, but most appear to date from the 1870s and 1880s – some possibly into the early or mid-1890s? Jars with the CFJCo monogram on the reverse are believed to be earlier than the jars with the monogram placed on the front. The jars are seen with a variety of base markings, usually consisting of a letter followed by a two or three-digit number – for example “J 26”, “A 120”, “D 339”, etc. On some jars, the numbers on the base are backwards, so of course will appear correct when looking down through the mouth of the jar. A large number of different molds were used over many years at the various factories that produced the jars. Many slightly different shades of color are known, although the most common color seen, by far, would be classed as a light aqua or blueish-green. A few jar examples have been seen bearing a Christian cross along with the mold letter/number on the bottom. For more background info, check out Bill Lockhart’s detailed article here: Consolidated Fruit Jar Company – SHA.org . Note : there are also some modern reproduction fruit jars with this “CFJCo” monogram on them as well, so careful research is needed.

………………..many types of bottles produced over the years are seen that bear a crown logo on them – in some cases as part of a brand name or trademark but sometimes as a decorative feature or perhaps just a mold identifying mark (equivalent to a mold number). In particular this entry is referring to a rather ornate, fairly well designed “King’s Crown” that appears (often boldly embossed) on the base of aqua, “square footprint” pickle bottles that appear to date from sometime in the 1870s-1890s era. They are similar to the “Cathedral” style pickles but rather plain with less ornamentation. I think they were produced somewhere along the Eastern seaboard of the US, or perhaps in PA? Most are rather tall, usually between 9 and 14 inches in height. I am not aware of the meaning of this particular crown design. Perhaps the trademark of a pickle/condiment distributor? A wholesale food company? A company logo? If you have information on the user of this particular crown design seen on the bases of these pickle bottles, please contact us! Thank you!

……………………….Davey & Moore, Limited, Brimsdown, Middlesex (London), England (c. 1805- 1980). Julian Toulouse ( Bottle Makers and their Marks , page 153) stated this mark dated after 1900, relying on information supplied to him from a contact (Mr. P.E.W. Harrison) who worked for Davey & Moore. The mark has been verified to exist on several bottles, including an aqua handmade round pickle bottle with crudely applied lip that was listed on ebay in 2021. That bottle looks older than 1900 (to me) but it may in fact be post- 1900, as Toulouse wrote that Davey & Moore continued to make handblown bottles even as late as 1925. Information about the early days of Davey & Moore are virtually nonexistent on the internet and I have found no concrete evidence to show any -making firm under the exact name “Davey & Moore” even existed until c. 1873, and that according to a brief mention on a .pdf file article indexed at the planning.islington.gov.uk site [URL was moved or deleted in recent years, and I can’t find it now], indicating that the company had just moved to a location on Albion Road (now 55 Balfe Street) and later (circa 1895-1897) moved to 33 Blundell Street, Caledonian Road. The Statistics of British Commerce (Braithwaite Poole, 1852) with stats probably collected in the 1849-1850 period, does not have a listing for this company. Davey & Moore engaged in the manufacture of “drain pipe (stoneware)” according to a business listing in J.A. Berly’s British, American and Continental Electrical Directory published in 1883. The making operation located on Lockfield Avenue in Brimsdown may have began much later, perhaps not until the 1930s. Davey & Moore was absorbed by United Bottle Manufacturers, Ltd (UGB) in the 1960s or ’70s and eventually closed down in 1980. Also, see the “D” entry, said to be an earlier mark also used by Davey & Moore.

Mfg Co., according to info published in Ketchup, Pickles, Sauces (1980) by Betty Zumwalt, was a food products firm, specializing in packaging pickles, as well as various relishes, sauces and other condiments.

A very few bottles have been found with a “D G CO” on the base and in those cases the maker of the bottle is uncertain – but Diamond of Royersford may be the more likely source. Other possibilities for some of these marks include Dixie Company, Tallapoosa, Georgia (1898-c.1906 or later). There is ongoing uncertainty about some of these bottles and their true maker.

…………………… Dominion Company, based in Pointe Ste Charles (Montreal), Quebec, Canada with other factory locations including Hamilton, Ontario; Wallaceburg, Ontario; Redcliff, Alberta; Burnaby, British Columbia; and Bramalea (in Brampton), Ontario, Canada. (1913- c. 1976). The “D within a diamond” mark was reportedly first used by Dominion in 1928 and continued to be used until about 1976. Dominion started as Diamond Company, Limited in 1890. Dominion became Domglas, Ltd. in 1976, Domglas Inc. in 1978, then was purchased by Consumers Packaging, Inc. in 1989, later Consumers . (See “C in a triangle” for their mark). Consumers was acquired by Owens-Illinois Canada Corporation in 2001 (now [2024] O-I Canada). Dominion was the largest container manufacturer in Canada, producing huge quantities of many types of bottles and jars over a long period of time. The mark used from 1913 to 1928 was evidently just a plain diamond with no letter inside (at least on their electrical insulators), but I don’t know if the mark used on their bottles followed the same appearance or timeline. See “Diamond logo” farther down on this page.

A prolific producer of soda and beer bottles, especially Hutchinson-style sodas (“hutches”) as well as crown-top bottles after the mid-1890s. The company produced both mouthblown and machine-made bottles. The initials are often found embossed on the lower heel of the bottle along with a mold number. For some background information on this operation and other Cunningham-related companies, see Jay Hawkins’ reference book “ Glasshouses and Manufacturers of the Pittsburgh Region 1795-1910 “.

It is likely that most, if not all, bottles with this and the much more common “D. S. G. Co.” mark were made during the 1878-1883 time period. The DeSteiger factory burned in 1883 but was evidently rebuilt and taken over by a new owner (Alfred A. Paddon) in 1884, who continued to run that factory under the DeSteiger name for several years- until about 1889.

……………………..There are a number of bottles with this marking on the bottom, especially Owens-Illinois bottles mostly from the 1930s and 1940s. For instance, DES. PAT. 92148. This means “Bottle design was patented and assigned #92148 by the U.S. Patent and Trademark Office in Washington, DC.” A search online might bring up more information on some of these bottles, for example, searching the “Google Patents” database with that particular number shows that a patent was issued for that design in 1934. Keep in mind this does not mean that the bottle itself was made in that exact year, since a design may have been used for several years afterward, with many bottles produced for years after the patent was issued.

…………………… On some older bottles, primarily handmade examples, several raised dots or bumps are found on the base. In most cases, they served the purpose of a mold number — merely a unique “mark” that identified a particular mold in a factory, especially when a number of identical molds were being used to make a certain type of container. The dots may be arranged in various orientations or geometric patterns. They are seen on case gins, snuff jars, ale, beer and soda bottles, and some older fruit jars and other bottles. In the case of snuff jars, myths have circulated for decades among bottle collectors that the dots seen on the bases of those jars indicate the strength of the snuff, or are date codes. This is not true, as explained in an article published in Old Bottle Magazine , February 1972 issue, page 10. (The number of dots – and their exact orientation – merely identified bottle molds on the automatic machine). Also, please see my entries under “X”, “Star” as well as my page on Numbers seen on the Bottoms of Bottles . Also, this is not in reference to a single raised bump often seen in the very center of the base – that is called a mamelon ).

……………………..Dyottville Works, Philadelphia, Pennsylvania (c. 1833-c. 1899). This operation, located in the suburb of Kensington in Philadelphia, had long been known as Kensington Works (c. 1816 to 1833). Dr. Thomas W. Dyott (1771-1861) was heavily involved in the works early on, and by about 1821 was part, if not full, owner and manager of the operation. Beginning in the early 1820s and possibly into the early 1830s a number of flasks were made that bear the marking “KENSINGTON WORKS PHILADELPHIA” and / or “T. W. D.” on them. (See “Kensington Works” entry on page three). Dyott gradually expanded the works and implemented the building of an extensive complex or small “town” around the glassworks which became known as “Dyottville”, with the factory itself – consisting of several separate factory buildings and accompanying outbuildings – being known as the Dyottville Works – by around 1833 if not before. Dyott filed for bankruptcy in 1838 and the works were shut down for some period of time between 1839 and 1842, later to be reopened, continuing on and off under several other operating firms until about 1899. (The exact ending year has not been determined with certainty). The Dyottville Works produced large numbers of pictorial / historical flasks (such as some of the Washington/Taylor “The Father of His Country” flasks, in particular GI-37 and GI-38 (in the McKearin figured flask classification system) and those could date from the late 1840s and possibly into the early or mid-1850s. (Note – reproductions of those particular flasks have been made in modern times by other makers including Clevenger Brothers – consult knowledgeable flask experts to determine if a particular example is a real Dyottville flask or a later copy). Other bottles found with the Dyottville embossing include a large number of lettered blob top soda and porter style bottles that probably date mostly from the 1850s-1860s period, as well as cylinder whiskey bottles that likely also date from that general time period and some possibly as late as the 1870s or 1880s. Some of the cylinder whiskies are lettered “PHILA” instead of “PHILAD’A”. Most of the Dyottville production over the many years it was in business, under several owners, was not marked.

………….. Unidentified, but on some early (handmade) bottles, this letter could possibly stand for any of a number of early bottle companies, including Ellenville Works of Ellenville, New York (1836-c. 1894 – operating under several slightly different factory names), as well as several Pittsburgh operations such as T. A. Evans & Company (c.1860-1869), Enterprise Company (1 st of that name, c. 1871-1873) or Eclipse Works (c.1875-1893). (Eclipse Works was located in the “Temperanceville” area of Pittsburgh – one of several factories operated by Thomas Wightman & Company). Another possibility would be Edward H. Everett Company of Newark, Ohio. See “ . H. . Co” and “ N next to (or within) a star “ marks. (In a book about Edward H. Everett and his company – Edward Hamlin Everett – The Bottle King by G. Wallace Chessman & Curtis W. Abbott, 1991 – a graphic is shown that includes “ 1” through “ 5” as marks used by Everett. However, no indication is presented on the source of that information or what types of bottles were marked thus). In some cases it is possible the letter could be merely a mold identifier or “shop letter”, as seen on the bottom of some beer bottles. The type of bottle most commonly seen with a single letter “ ” on the base, often accompanied by a mold number (1, 2, or 3) placed below the letter, is the Doyle’s Hop Bitters , usually found in some shade of amber. In those cases, judging from the years in business and the fact that Doyle’s was based in Rochester, NY, I think Ellenville Works is the more likely contender for the “ ” mark – at least on those particular bottles! Ellenville is known to have manufactured Hop Bitters bottles ( Poughkeepsie Eagle-News , May 10, 1881 issue, page 1).

Alling (1843-1910) was an ink and mucilage manufacturer based in Rochester, NY who started his business in about 1867. He began by selling stationery and related goods and then expanded into manufacturing inks, eventually selling a wide variety of inks and related products for many years thereafter. A number of different types of ink bottles (including cone, igloo, and schoolhouse or carmine types), are known with his name or initials embossed on them.

………………. Florida Manufacturing Company, Jacksonville, Florida (1926- c.1947). Julian Toulouse ( Bottle Makers and their Marks , 1971, page 199) indicates this mark dates from “circa 1930”. Another minor variation is also pictured: F and G entwined (superimposed over each other) which he writes as dating “circa 1940”. According to Toulouse, Florida Manufacturing Company was purchased by Chattanooga Company in 1947 (See “C in a circle” mark) , then leased by Ball for a year, and subsequently sold back to Antonio Scalise in 1950 who changed the name of the concern to “Tropical & Box Company” in about 1952. This Jacksonville plant eventually became Anchor Hocking’s plant number 7. Some milk bottles marked “ ” also bear the number “60” to the immediate right of the letters. Also, a few half-pint size milk bottles marked “ CO. 60” (and at least one marked “ CO 160”) on the lower heel are products of Florida . The “F.

…………………… meaning unclear. (Note – this mark includes a lower case “o” in Co). A very small number of bottles have been found with “ ” embossed on the base and there is uncertainty about what those initials actually stand for. They are much older bottles than those known to have been made by Florida Mfg. Company (see F G and F.G.CO. entries above). Although Toulouse (Bottle Makers and their Marks, 1971, page 200) attributes this mark to Fairmount Company of Fairmount, Indiana, claiming it’s use from 1889 to 1898, this seems open to question. (see Fairmount Works page on this site). An amber medicinal flask and an amber “pony” style beer bottle are marked with “F.G.Co.”. Also, a clear handmade ink bottle is known, and that bottle may have been made in Canada or England. Photos of those bottles are shown in this article from Bill Lockhart et al, here: Florida Mfg.

Other bottles are possibly out there that I’m not aware of. After many years of being an “unknown mark” , the correct identification of the user of this mark has been uncovered by researcher Josh McIntyre who kindly passed along this information to us [11/2025]. The exact time of closure of the operation is yet uncertain, but Josh is continuing to do more research on this short-lived glassworks. The factory property evidently sat empty for a number of years, and was then purchased and renovated to become a brick manufacturing operation in about 1895.

General offices in Pittsburgh, actual factory locations were at Tarentum, Leechburg, New Brighton, California, Charleroi and Beaver Falls, all in Pennsylvania. The period of usage of this particular mark is uncertain. Although the mark is listed in “ Milk Bottles: Their Makers and Marks ” by Jeffrey L. Giarde (1980) on page 22, and he dates it as “1900 – 1928”, Giarde might have been copying Julian Toulouse’s info in “ Bottle Makers and their Marks ” (1971). I have only heard about one milk bottle confirmed to have this mark – but on the heel, not the base. If you have seen ANY bottles bearing an “F in a keystone” mark, please write!

Knittle notes that “ & CO.” appears on a Union-Clasped Hands pictorial flask, but McKearin & Wilson (1978:651) show that the mark as “L.F.& Co”. In any case that flask would certainly date from the 1860s or 1870s. See “F R L”.

Toulouse illustrated this mark (page 205, Bottle Makers and their Marks ) and stated it is “modern”, likely dating no farther back than World War II. The two letter F’s are in cursive font and may be somewhat “tall” and “thin”, slightly more so than the letters in the very similar mark used by Foster-Forbes in the United States. These marks may be easily confused, but if the container was found in Great Britain it is much more likely to represent Forster’s Co., rather than Foster-Forbes. (See FGC mark).

……………….. Foster-Forbes Company, Marion, Indiana and (later) several other plant locations. (1929-2000). This particular mark was first used in 1942 and is seen on the bottoms of many kinds of bottles including those made for soda, beer, food, medicine, cleaning products, etc. The exact ENDING year of use of this mark seems a bit uncertain, but I have seen emerald green soda bottles with date codes for 1986 and 1990. Foster-Forbes Co. was merged into National Can Company in 1969 and eventually National Can Company was merged with other interests to form American National Can Company in 1987 (see American National Can Company mark on Page One )- however at least some bottles made at some of the Foster-Forbes plants under this corporation “umbrella” continued to use the “FF in a circle” mark – at least as late as 1990 and possibly as late as 1995. Sometimes the mark is faint and very hard to discern and in some cases the cursive “FF” is interpreted as “33” with the numbers having a somewhat flat top, or as a “JJ connected, inside a circle” ! Some of the former Foster-Forbes plants are no longer in operation, and others are part of the present-day Ardagh Group (formerly owned by Saint Gobain, later Verallia). Saint-Gobain Containers products usually have an “SG” on the heel or base (see my page on the “ SG” mark used by Saint-Gobain ) . For an earlier mark used by Forbes ( 1929-c. 1942), see entry under “Z” (Backward Z with a slash through the center) on Page Five .

………………. Fire & Light, Arcata, California (1995-2019). Located in northern California (Humboldt County), this independent studio operation produced handmade glassware from recycled (mostly from crushed bottles), and has gained a devoted following among collectors. Many types of products were made including bowls, plates, tumblers, ashtrays, votive candleholders and other novelty items, in a wide range of colors. Many pieces seem “heavy” in weight for their size. Most (although not all) of the pieces, especially the bowls, plates and tumblers, feature a somewhat uneven surface (which might be described as “hammered”, bumpy, corrugated, irregular, or subtly crinkled or pebbly). Only a minority of pieces were signed, usually on the base or edge of the piece. Sadly, the operation ceased production and closed down permanently in April of 2019, evidently because of financial issues.

Large numbers of drinking mugs and cups have been made with the brand name logo on the bottom, and these are avidly collected today, especially by the so-called “baby boomers” growing up during the 1940s, 1950s and 1960s, when so many of these items were in popular use in most American homes. Many of the mugs and bowls have surface-applied color decoration, which sometimes begins to wear off, thus washing them in an automatic dishwasher is strongly discouraged. Vintage ware has great nostalgic value, and can be seen frequently for sale at antique malls, flea markets and garage sales.

g A c (capital A, with smaller, yet upper case, “G” and “C” placed on both sides, as shown) …………………… for several years I had this mark listed as “unknown manufacturer”, but recently (9/2023) have discovered this is an early mark (most likely the very earliest mark) used by Arkansas Container Corporation of Jonesboro, Arkansas (1956- to present). (Julian Toulouse listed a single capital “A” mark as the earliest mark they used, but I’ve not seen it on any containers). This gAc mark has been seen on a variety of utilitarian/packer jars of various sizes, as well as on a syrup dispenser jar. The mark also appears on the bottom of a large jug made for sun tea that came with a yellow plastic lid, probably from the late 1960s or early 1970s. In some cases the “A” is quite large and the “G” and “C” are like two small “footnote letters” positioned to the lower left and right of the “A”. (Thanks to Melissa Alonzo for her help with this mark! She sent me photos of an older cardboard shipping box containing jars that proved conclusively this mark was connected with Arkansas Container).

Many item listings on ebay, etsy and other sites repeat this mistaken belief. Actually, the “capital W with dots” almost certainly represents a “Crown with jewels” and is merely part of the entire trademark as used by Gemco.

…………………… Ware, Inc., Freeport, New York, later [after 1999] at Hauppauge, New York (1948-2003), marketed a variety of kitchen-related items including salt and pepper shakers, sugar shakers, syrup pitchers, measuring cups, and other items of that nature. The company was acquired by Lifetime Hoan Corporation in 2003. The embossed name “ ” appears on the base of many of the items they distributed / sold. The actual manufacturer of the glassware marked “ ” is unclear. Some of the milk items bear a strong resemblance to the “Corelle Ware” line of kitchenware sold by Corning, but the items (of that particular line of ware, usually in milk ) were intended to “coordinate” with Corning Ware, and was, in effect, a competitor to Corning, and not a product of that company. Contrary to some information on the web (including info I have put on my site in the past), this is evidently unrelated to another “ ” brand name, a chain of department stores (in business from 1959 to 1986). If anyone knows for sure what manufacturer (or manufacturers) actually made the glassware marked “ ”, please write! Also, please see “G W with three dots” entry farther down on this page.

The beginnings of this enterprise date as far back as 1844. In 1900 Gijon Industrial was formed, which was superseded in 1915 by Gijon Fabril. Bottles and other glassware were made in large quantities until 1982 when the factory became a mold-making facility. The most well-known bottles made by this company, of green , were made for cider, a very popular beverage produced in Gijon.

The line was introduced in 1917, and competed with Pyrex (made by Corning Works) and Fire-King (Anchor Hocking Corporation). The formula was changed (after a lawsuit was filed by Corning) and re-introduced in 1919. The brand was used more or less continuously throughout the succeeding years, under Thatcher ownership (1951-1961), and later by Jeannette Company until 1979.

However, this doesn’t rule out the possibility that a mark similar to this one could be seen on products from other factories. Type of bottle, age, color, and other characteristics must be taken into account to decide if this would be a Hemingray product. NOTE: If the number consists of either one or three digits, it is not Hemingray. On Heinz bottles, a number (which may consist of one, two, or three digits) which accompanies an “H” on the base refers to a particular design or style of bottle made by Heinz, and is not Hemingray-related.

The Hall’s company was based in Nashua, New Hampshire.

The mark is a stylized monogram of the letters “H” and “E” and may be hard to decipher at a quick glance, resembling a Greek numeral or ancient hieroglyphic symbol. When turned to the left, it might be described as a highly simplified stick figure of a menorah. This mark is mentioned in the reference book “Eye Baths – An Illustrated Survey” by George Sturrock (2012) and the logo is also shown in a 2016 news article webpage on the site of Apothecary Products. According to Sturrock, the eye baths made for HE were produced by a company in Hong Kong. The Health Enterprises company sold eye baths beginning in 1990.

……………………………….. H. J. Heinz Company, Sharpsburg, Pennsylvania (c.1892-1946). Heinz (started by entrepreneur Henry J. Heinz) is best known in the United States (and worldwide) for their iconic brand of ketchup, as well as a wide variety of other condiments, sauces, soups and other food products. Bottles marked “Heinz” or “H. J. Heinz” and other variations were made for many years, possibly dating back to the first incarnation of Heinz’ company circa 1860. From c. 1860 to about 1892, bottles with those markings would have been manufactured by unidentified glassmakers. Heinz acquired a factory in Sharpsburg for his own products, evidently beginning production sometime in late 1892 or early 1893. Several years later he built a new, larger factory at Sharpsburg for producing bottles for his products. After 1946, many of Heinz’s bottles were again made by other manufacturers such as Hazel-Atlas (H over A) and Owens-Illinois Company. Please see “H” and “H-28” marks. Note : for a discussion on Heinz, with pictures of dozens of the older HEINZ-embossed food bottles that have been found, check out Betty Zumwalt’s ground-breaking reference work Ketchups, Pickles, Sauces (1980).

……………..uncertain, but possibly Abramson-Heunisch Company. Most earlier researchers, copying info from Julian Toulouse’s Bottle Makers and their Marks (1971) credited Holt Works of Berkeley, California as the source of these bottles. That attribution is now under considerable doubt. More recently (2016), archeologist and historian Bill Lockhart has gathered evidence to indicate some of these bottles found in the western states, typically with a number (one, two, or three digits) accompanying the “H”, may have been manufactured by Abramson-Heunisch Company, San Francisco, CA (1893-1902 – and perhaps extending into bottle production during the early years of Illinois-Pacific Company, up to circa 1907, when Adam Heunisch was the president of I-P G CO) . See this link: The Great Holt Myth: A Study of Misidentification for more background explanation on Holt and Heunisch. In most cases, the number is placed above the “H”, although in some cases is may appear either below, or positioned to the right of the letter. Please keep in mind that positive attribution of a bottle with an “H” mark to any definite glasshouse is often very uncertain. Please see next two entries.

The “70” was the liquor bottle permit number assigned to Hart – that code was also used for a short time by Armstrong Cork Company (Hart’s Dunkirk facility was acquired by Armstrong in 1938), perhaps in the 1938-1940 time frame. Other Hart bottles may exist, but this is one example of a bottle bearing an “H” which can be strongly tied to Hart.

……………….. Illinois Company, Alton, Illinois (1873-1929). This mark was used possibly as early as the mid-1870s to around 1900, and may appear on either the base or the heel of various bottles, and was also used for several years after 1900 primarily on the lower heels of their soda bottles (since the base would frequently be reserved for the logo or initials of the bottling company a bottle was made for). The “O” in “Co” may be either upper case or lower case. Use of the mark on certain soda bottles is known to have extended at least to 1909, perhaps 1911. Please see “ .L”, “IGCO within a diamond” and “ I within a diamond ” marks. Illinois Company merged with Owens Bottle Company in 1929 to form the Owens-Illinois Company .

For more information on Imperial and their history and marks that were used, please check out this site: Imperial Company history – Imperialglass.org . On many items, the mark is small, lightly embossed, and can be rather difficult to make out. At a quick glance it might resemble a “cents sign”, “dollar sign” or treble clef sign in sheet music. Sometimes the letter “I” looks somewhat like an ornately designed number “1”. The letter “G” is often mistaken for a “C”.

I within an “O” or oval (shown above) ……………………………………………………… see this page with more info: Owens-Illinois Company . Owens-Illinois, formerly headquartered at Toledo, OH, now Perrysburg, Ohio (1929 to present), has used three major trademarks over the last 90+ years. (“ Diamond and oval entwined with I in the center “; “ I inside an O “, and presently simply “ O-I “). Approximately 25 manufacturing factories are located in the US and Canada, with the most recently opened plant at Windsor, Colorado. This mark was used beginning in 1954, up to quite recently, being gradually replaced (over a period of several years) with the “ O-I ” mark (the current mark used by O-I) on most bottle molds. The diamond was removed from the “old” mark beginning in 1954, although a few bottle molds apparently didn’t have the diamond eliminated (i.e., the mold retooled) until years later, even as late as 1966. After c. 1958 the great majority of O-I bottles carried this simplified mark of just an “I inside an O”. On recent bottles, this mark may be small, faint, and not always easily discernible, usually seen embossed on the heel of the container. O-I is presently (2024) the largest making corporation in the world. A wide variety of containers are made, many especially for food and beverage products. For more information on this mark and several others used by Owens-Illinois over the years, see this page: Owens-Illinois Company .

………………… uncertain meaning, but possibly Kentucky Cooperative Company, Louisville, Kentucky (1897-1898). On some bottles, these initials may stand for another company. Kentucky Cooperative went into receivership in 1898 and was reorganized to become the “Louisville Company” (also called the Louisville Bottle Manufacturing Company), a short-lived venture that ceased by 1901 (and not to be confused with the much earlier Louisville Works (1855-1873). The “K. G. Co.” initials are seen on the reverse heel of a small number of mouthblown soda bottles (most of which are of the “hutch” style) including bottles marked “M. Bochart / Jeffersonville, Ind”; “F. & P. Bochart / New Albany, Ind”; “American Bottling Works / Louisville, KY”; J. I. Marsh / Portsmouth, O”; “H. C. Kunkel / Michigan City, Indiana” and Cartens Bros. / Cincinnati, Ohio”, all, except for the Michigan City bottler, are located on the Ohio River. Two “outliers” include “A. Weber / Union City, Conn” and “Enterprise Soda Works / S.F.” . Also – a light greenish-aqua “champagne blob top” style beer bottle is marked “H. Neiman / Bottler / Chicago” in a slug plate and “K. G. Co.” on the heel. The maker (in my opinion) of the bottles made for the bottling outfits located along the Ohio River is most likely Kentucky Cooperative Company, even though the extra “C” in the name does cast some doubt on that attribution. Louisville, New Albany and Jeffersonville are all located very close to each other. And all of those bottling firms were operating in the late 1890s. The bottles from Connecticut and California may be totally unrelated. A tall narrow “ammonia type” medicinal bottle in aqua (which also looks 1890s) is marked on the bottom with “K G CO” (see photo). Researcher Bill Lockhart writes that the K G CO mark was most likely used by Kanawha Co, of Cedar Grove, West Virginia – an obscure bottle company that operated circa 1913-1914 (no relation to the much later Kanawha Company that made tableware 1955-1989) – but I feel that company was too late to produce the hutch sodas that were more typical of late 1890s production. Perhaps more research will uncover what these initials stand for – for sure!

Sometimes there is no discernible letter inside the keystone shape. Originally, the main Knox plant at Knox, PA used the “ ” (c. 1932) and most, if not all, of their other factory locations instead used a different letter inside the keystone at that time. However, most of the Knox factories are believed to have switched over to using the “ ” mark after about 1953, continuing on up to 1968 when Knox was bought out by Containers Corporation.

………………… Keene Works / Keene-Marlboro Street Works, Keene, New Hampshire (1815-1842). Keene is located in Cheshire County, in southwestern New Hampshire. This glassworks operated under a number of firm names (partnerships / business names) over the years, including Twitchell & Schoolcraft (1815-1816); Justus Perry (1817-1822); Perry & Wood (1822-1826); Perry & Wheeler (1826-1830); Perry, Wheeler & Company (1830-1835); and S. & Q. Wheeler (1835-c. 1842). Subsequent operation was sporadic and reportedly lasted until around 1850. There is a commemorative historical marker / plaque erected in the city of Keene that dates this particular works as “1815-1842”. (Another factory in Keene made mostly window , not bottles. It was located on Washington Street). Most of the output of the Keene Marlboro Street factory was not marked. It made a wide variety of bottles. However, a few Masonic flasks were marked, including GIV-17 (the McKearin figured flask classification number) which is embossed “KEENE”, and 3 variants of that general type that are lettered “KCCNC” – the mold engraver neglected (either accidentally or purposely) to place a central bar in the “E”s. The embossed letters are sometimes faint or indistinct and hard to discern. The three variants lettered “KCCNC” are catalogued as GIV-18, GIV-19 and GIV-20. Most of these bottles were made in shades of amber-colored . The front of the flasks feature Masonic symbols and the reverse bears a representation of an eagle, with the oval “frame” placed below the eagle. There is confusion and conflicting date ranges given for the years when the “KEENE” and “KCCNC” marked flasks were actually produced. The most likely date range (in my opinion, and you can take that with a grain of salt) is from circa 1822 to 1835. Several other flask variants, also believed to be products of this glassworks, include examples marked “IP”, “HS”, “H-P”, “P & W” and “J. K. B.” in an oval frame. The “I-P” is actually “J P” and stands for Justus Perry. For more details on this factory, check out this article from Bill Lockhart: Keene-Marlboro-Street Glassworks – SHA.org.

………………… Kensington Works, Philadelphia, Pennsylvania (c.1816-1833) and (1842-1846). Full name seen embossed on a number of early figural / historical flasks. Flasks made at the Kensington works include GI-14, GI-16 and the GI-90 through GI-96 variants. researcher and author Helen McKearin dated those, in general, as having been made beginning around 1824 with production continuing for an undetermined stretch of years thereafter. Dr. Thomas W. Dyott was either part-owner or full owner and manager of this works by around 1821. This factory (or, more accurately, factories – by 1833 there were four or five separate factory buildings) was later known as the Dyottville Works (see “Dyottville Works” entry on page two) . Some of the early flasks made by the Kensington Works were marked “T.W.D” (for Thomas W. Dyott). T. W. Dyott went bankrupt in about 1839 and there would be a succession of other operating firms that ran the glassworks over several more decades, with some intervening periods of inactivity. NOTE: a number of pontiled soda bottles from the 1840s are also known with the marking “KENSINGTON WORKS” [no “PHILADELPHIA”] but these were made in the c. 1842-1846 time period after chemist Henry Sybert re-opened the idle Dyottville glassworks to make mineral water bottles for Eugene Roussel. The works were then sold in 1846 to Benner’s Smith & Campbell, who ran the plant as “Dyottville Works” (source: research by Tod Von Mechow). An overview of the Kensington Works and Dyottville Works (by Bill Lockhart et al) can be found here: Dyottville Works

………………… a type of mold associated with handmade (mouthblown) antique bottles, typically characterized by a “line-semicircle-line” mold mark on the base of the bottle. The mold mark may or may not be easily discernable, and sometimes may be partially obscured by a pontil mark. Although it is difficult to pin down a specific age to such bottles, in general, this type of mold was most often used with bottles made in the c. 1845 to c. 1875 time period in the US. For more in-depth information on this type of bottle mold (as well as others), check out this page on Bill Lindsey’s site: Bottle Bases – Historic Bottle Information Website.

Lamb made many of the earlier “Babyface” milk bottles in clear , which are now being reproduced (usually in brightly colored such as cobalt blue) by factories in China & Taiwan. The Lamb Company factory was purchased by the Dorsey Corporation (owners of Chattanooga Company, Chattanooga, TN) in 1963. After 1963, the “L52″mark was evidently continued on milk bottles, but some other types of containers made at the Mt. Vernon plant bore the “C in a circle” mark used by Chattanooga Co. The L52 mark on milk bottles was probably continued in use until around 1971. The exact year of ending of the L52 mark is rather “fuzzy” as Lamb usually didn’t place date codes on their containers – or, at least, date codes that were easily interpreted as such. See “L” and “L G Co.” entries. See also L.G.CO. mark: Lindell, Lyndeboro, Lockport and Lamb Companies.

The “ ” may appear on the heel of a bottle, but is often seen on the bases of soda bottles, along with mold , date, and/or style code numbers. Often, the LGW mark (as used by Laurens) is situated between numbers (date codes) such as: “6 1”. That would indicate a bottle made in 1961. Also, see the “L” mark entry on this page. NOTE: In some instances certain older (pre-1900) bottles or flasks with the marking “L & W” (indicating Lorenz and Wightman) are misunderstood to read “L. G.

Notable examples are on Coca-Cola bottles of the 1934-1951 period, wherein the L appears on the side of the bottle, placed between a mold number and a date code. This “L” is also seen on the base of “Longlife Mason” jars. The “L” identification mark is also believed to have been used on many of their bottles after around 1970.

……………these bottles were evidently imported to the US from France, although the exact meaning of the initials is not yet known as far as I can tell. For many years these bottles were considered to be a mystery, but recently an example was found with an original paper label, indicating the bottle contained “imported capers”. Though this one label doesn’t prove ALL of those bottles contained capers, we can be reasonably sure most, if not all, contained some kind of pickled food product. The bottles probably date from the 1880s to around 1910, although some examples, apparently older, are known with pontiled bases. They have been seen in a range of true green shades including olive green and emerald green. Possibly other colors exist. They are found in three different sizes. Note that many of the bottles are unmarked , so only a percentage of them bear these initials. These barrel-shaped bottles are mentioned in the classic reference book Ketchup, Pickles, Sauces – 19th Century Food in by Betty Zumwalt (published in 1980) on page 264.

The blob-type soda bottles most likely date from the 1850s-1870s period. The works was operated by several owners/firms over the years. Francis Hitchins operated the company circa 1850-1866, and some bottles made during that time period were marked “ From F. Hitchins Factory, Lockport, N.Y”. Alonzo Mansfield bought this factory in 1872 and it then became known as the Mansfield Works, although the factory may have unofficially been called the or Lockport Manufacturing Company for several years afterward, at least into the 1880s if not later.

……………………… a plain “ ” is also seen on the base of certain mouth-blown amber, aqua and clear beer bottles (and a smooth-lip amber handmade salve or cold cream jar, photo below) that appear to date c. 1880-1910, and the glassmaker in those cases predates Maryland and to my knowledge has not been identified with absolute certainty . (For instance, some beer bottles marked “F. & P. BOCHART, NEW ALBANY, IND” are marked with a plain “ ” on the bottom, and those would date sometime between 1890 and 1907, judging from the years that bottler was in business). That unidentified manufacturer was probably located somewhere in the Midwest, i.e. IL, IN, OH or PA. There were a number of bottle factories just in those states with a name beginning with “ ”, which shows why it is so hard to know for certain who the maker of those bottles was. Researcher Bill Lockhart believes that Massillon Works, of Massillon, Ohio (1881-1904) could be the source of the “ ” mark on beer bottles. Some of the “ ” marks appear with numbers or letters (see my “ B” entry on this page). For in-depth information on the marks attributed to that glassmaker (also known as Reed & Company), see this .pdf article: Reed & Company and the Massillon Works . There is also a good possibility that this “plain ” indicates Modes Company of Cicero, Indiana (1894-c. 1902), since examples of “F. & P. Bochart, New Albany, Ind” beer bottles have been found with both (either) a “plain ” OR an “ G CO” marking which, in the latter case, almost certainly indicates Modes Company (see my page on .G.Co. bottles here) : .G.CO. marks on antique bottles & fruit jars (Mississippi, Missouri, Modes) . Thus I feel that the “ ” mark may indicate the very same manufacturer that made those “ G CO” bottles for Bochart. NOTE: In some cases a “plain ” may be the mark of the Mosser Company, Cambridge, Ohio (1971-to date) but in those cases it would appear on upscale, colorful decorative and novelty glassware, NOT utilitarian bottles or jars. See “ inside a circle “ and “ within a G” entries, as well as next entry.

There is apparently no connection between this factory and the Mexican factory (see above) which also made insulators, although both marks are nearly identical in appearance. The Masnieres glassworks dates back to 1818 with various name/firm changes over the years. The range of dates this mark was used is uncertain, but might be from the 1920s-1950s?

…………… Uncertain meaning. This might be a case in which the “C” was intended to be a “G”. However there are jars known with mold numbers “3” as well as “4” and in both quart and half-gallon sizes.

If the letter was supposed to be a “G” the jars would presumably be products of the Mississippi Company of St. Louis, Missouri. Alice Creswick (The Fruit Jar Works) wrote that W. McCully & Company of Pittsburgh might be a possibility. Researcher Dick Roller (The Standard Fruit Jar Reference) wrote “maker unknown”. Please see the “M. G. CO.” page.

………… currently unidentified manufacturer. A rather small number of bottles have been found that could not have been made by Maryland Corporation, as they are mouthblown and date from before Maryland started using their “M in a circle” trademark in 1921. They are American-made, are found in colorless , are not machine-made, and would date from the 1880s-1890s – no later than around 1910. Some examples of these bottles include: a “Sunburst” design whiskey flask with a ground screw-top lip; a “Honey Suckle” choke-neck style back bar bottle with swirled design on shoulder; “Taylor & Williams Whiskey, Louisville, KY” cylinder whiskey; “Geo. T. Stagg Co, Frankfort, KY” cylinder; “V. E. Shields & Co, Cincinnati, O” flask; and a prescription-lip clear druggist-style bottle embossed “H. D. Block / 245 E. Jefferson St./ Louisville, KY” (actually a liquor distiller/distributor) on the front. Since most of these bottles appear to be from the KY/OH area, it is most likely that the unidentified bottle-making company was located in that general area, and (of course) had a company name beginning with the letter “M”. If anyone has good info on what company this could be, please let us know!

…………….. John M. Maris Company, wholesalers/jobbers of druggist ware, sundries, pharmacy “furniture”— this firm began in 1842 as Pleasants & Maris, name changed in 1846, business offices in Philadelphia and New York City. Still in business (2015) with offices currently based in Rockaway, New Jersey. John M. Maris Co. sold drugs wholesale until 1872 when they changed the focus somewhat and started selling a large line of druggist bottles and related ware (Pharmaceutical Era, Vol. 39, pge. 166, 1908). Apparently most (if not all) of the sold by Maris was actually manufactured by unnamed bottle companies, in early years almost certainly by Whitall Tatum & Company of Millville, New Jersey who specialized in druggist ware of all types. The “M in a diamond” mark is confirmed on several different items including a clear druggist bottle circa 1885; clear and cobalt blue eyewash cups; and a miniature clear mouth-blown lamp with a ground lip and metal screw-top wick assembly which was seen on ebay and said to have possibly been used for medical/laboratory purposes. Apothecary weights (tokens) are known with the “M inside a Diamond” logo. Also, confirmed as marked on the bottom of a milk cold cream jar, circa 1920s-1940s (but this item may or many not have any connection with Maris)? Also, please see next entry.

HOMCO (Home Interiors and Gifts, Inc), based in Carrollton, Texas (1957-2008). Mary C. Crowley, a struggling single mother with two small children, scraped up all her savings, and along with some other borrowed money started up her own small business in 1957, selling a selection of home decor items. The business model was somewhat similar to others such as Mary Kay, Tupperware and Amway, with much of the merchandise sold at “house parties”. Total sales grew rapidly and had reached into the millions of dollars by the 1970s. A wide variety of home decor items were sold including porcelain Victorian Lady figurines, candle holders and other home decor. Much of the merchandise sold by HOMCO was manufactured in Asia, although apparently at least some percentage of the glassware sold by Homco was made here in the United States- by Indiana Company of Dunkirk, Indiana (in business 1907-2002).

S in a diamond (vertically or horizontally oriented), on mouth-blown (handmade) bottles, at least in some instances, possibly Swindell Bros, Baltimore, Maryland (1869-1959). Some strap-side type flasks (most commonly found in the Eastern states) bear an “S inside a diamond” mark on the bottom and these are suspected to be products of Swindell Bros. They are typically found in shades of amber, olive green and occasionally citron. Swindell Bros. catalog pages indicate they made several types of liquor flasks in the 1880s-1890s period. HOWEVER , from the collection of papers held at the Winterthur Library pertaining to the career of Chas. Yockel and his mold manufacturing firm, there is a letter proving that the Chicago Manufacturing Co., of Chicago, IL, ordered bottle molds with an “S inside a diamond” on November 17, 1887. Evidently both Chicago and Swindell Bros. made large quantities of colorless prescription / druggist type bottles so this presents a problem for accurate attribution! Perhaps more enlightening information will be uncovered as time goes on.

Many of the fruit jars are marked across the front “HAMILTON / No 1 / WORKS” (and other numbers such as No. 2, No. 3 or No 4). Some jars were made for a cork closure, others are to be fitted with a lid and metal clamp-style closure.

Shear mark (minor defect / imperfection on the base of articles, created during the manufacturing process). The shear mark is typically “C” or crescent shaped and has been described as resembling a false eyelash, centipede, fern leaf, or feather. Shear marks are commonly seen on the bottom of machine-made bottles, jars, vases, mugs, drinking glasses, etc. Sometimes they are mistakenly believed to be emblems or logos of a specific company.

Star or “snowflake” design comprised of thin crossed lines (as shown) . This particular photo shows a base shard from a handblown dark olive green rectangular, square-based “Case Gin” type bottle imported to the US from Europe, likely Holland (Netherlands). Many different “crossed lines” designs have been seen on the bottoms of these kinds of bottles. Most of them date, in general, from the 1860 to 1920 period (although that general type of bottle was made as early as the 1620s). Although no one is 100 percent sure of the original purpose of these emblems, they are more likely to have been intended as mere decorative devices, and not glassmakers’ identification marks. See next “star” entry, also see my entry on “X” near the bottom of this page.

……………………..Unidentified with certainty. These initials appear on the base of an American-made aqua 12-sided “umbrella ink” bottle (shown above) which appears to date from the 1860s into the early 1870s. The base is a “key mold” type without a pontil mark. This is only one of two reports of this bottle (and mark) that I am aware of. One possibility, although tenuous: To my knowledge there is only one brief instance of the firm name “Wm McCully & Son” – evidently from the 1850-1852 timeline as seems to be implied on page 187 of “Allegheny County’s Hundred Years” (1888) by George Henry Thurston. However, the bottle on which this mark appears seems to post-date the early 1850s, so at this time I can’t say if that would be the correct attribution?!

Some sources imply that this “Box N” mark (and/or an “N in a rectangle) was first used as early as 1895, but Toulouse ( Bottle Makers and their Marks – 1971) states the “N inside a square” was first used on machine-made bottles circa 1915.

After 1915, on machine-made ware, the “N in a square” was instituted as their standard mark. On some bottles it’s hard to say if the “box” is better described as a “rectangle” or a “square”, as the whim of the mold engraver resulted in some variations in exact appearance – so any particular mark could lean in one direction or the other.

…………. probably Olean Company/Works, Olean, New York (1883-1913). There were two different companies known as Olean . This mark was evidently used by the first Olean Company, but only on a very small number of containers. (See the “OG in a circle” entry above.) It has been seen on the heel of Hutchinson style soda bottles. For more information on both companies that used this name, please check out the extensive article by Bill Lockhart and other researchers, at this link: The Olean Company . Olean also had a second factory located at Port Allegany, Pennsylvania (1896-1912), which in later years was successively occupied by Wightman Co-Operative Company (1915-1917) and then Pierce Company (1917-1987), currently (2021) being operated by Ardagh Group.

………………. Oil City Company, Oil City, Pennsylvania (1952-1984). This factory started production in 1930 under the name “Oil City Bottle Company”, which used an “O inside a keystone” logo on their bottles. In 1952 the factory was acquired by the Pyramid Rubber Company and evidently started using the new oil derrick trademark around that same time. This particular logo, a representation of an oil derrick or “oil drilling rig”, is seen on the bottom of a variety of bottles, and is sometimes misinterpreted as an electrical tower or some other type of “grid” structure. On some bottles the mark is small, distorted or faint and hard to make out. Two types of bottles frequently seen with this mark on the bottom include the “EVENFLO” brand baby bottles, and battery oil bottles (often found along railroad tracks) made for National Carbon Company. Salt shakers were also made in a characteristic “oil derrick” shape and marked on the base with the logo. (The shakers were made sporadically, over some time, and back-stocks were kept in the storage room and gradually sold over a period of time, perhaps even years after actually being made). Julian Toulouse ( Bottle Makers and their Marks , 1971) wrote that this mark was used from 1952 to 1969 . However, I have seen a clear flat liquor flask with the derrick mark and a 1970 date code. The Oil City Company was purchased by the Questor Corporation [what year?] , and the Questor Corporation sold the factory to National Can Corporation in 1969. After 1969, the factory operated under the Foster-Forbes Division of National Can Corporation, although the plant was often referred to by locals as the Oil City Co. factory for many years afterward. The last bottles made at the Oil City factory were produced on April 13, 1984, according to information posted about a commemorative bottle listed on ebay (that listing later placed in the Worthopedia database). Evidently the oil derrick logo was phased out in the 1969-1970 time frame, although it might have taken a little while before all the bottle molds (mold base plates) in use were retooled with the “FF in a circle” logo used by Foster-Forbes. Also, please see “O in a keystone” entry, above on this page. (Also, thank you to former factory moldmaker John Pochran – I had a nice conversation with him by phone on 8/17/2022).

OOOO (monogram that appears to be four connected “Os”, zeros or circles, or a group of closely connected rings, almost a cloverleaf, somewhat similar to the Olympics logo but with four instead of five “rings”). Some have described it as a flower bloom with four petals…………………….. trademark used by Libbey-St. Clair Inc., company headquarters in Mississauga, Ontario, Canada, factory located in Wallaceburg, Ontario, Canada (1978-c.1993). Several years ago, this mark (above) was reported to me as having been seen on the bases of restaurant glassware (such as mugs, tumblers) purchased in Canada. Sometime later I received information from reader Lisa Wallis that this mark was used by Libbey-St Clair, Inc. Currently, there seems to be relatively little detailed information online about that firm, but evidently it was formed in 1978. The site itself was originally that of Sydenham Company, dating from 1895, later Dominion Company, later DomGlas. From this page: Diamond Flint/Dominion /Domglas – 11th in Canadiana Series – Mandicrafts.blogspot.com , we read “In 1978 Dominion’s Wallaceburg Ontario factory was taken over by CB Pak and the plant became Libbey-St. Clair. It was renamed Libbey Canada when Libbey Inc purchased its assets in 1993.” On another site (on an Instagram post) someone wrote: ” In 1978, the glassworks in Wallaceburg, Ontario, Canada came under the ownership of the Owens-Illinois Company of Toledo, Ohio (Libbey was a subsidiary of OI at the time) and the works became known as Libbey-St. Clair.” By all accounts, the plant was closed in 1999 under the name “Libbey Canada Incorporated”.

………….. this mark stands for “Olde Virginia ” which was a line of colored decorative glassware sold by Fenton Art Company of Williamstown, West Virginia (1905-2011) . That particular line of glassware included such items as compotes, vases, bowls, salt shakers, candy dishes, decorative booties, shoes and hat-shaped toothpick holders. Most of the glassware sold as OVG are pieces in the “Daisy & Button” and “Fine Cut and Block” patterns. OVG was evidently sold as a slightly lower-cost alternative to their regular line, and was distributed in department stores such as K-Mart and sold in exchange for redeemed books of S & H green trading stamps. Information found online about the exact time period that Olde Virginia was produced seems contradictory in some cases. Some sites/webpages report the line was introduced as early as 1960. I think that is probably incorrect. Other sources indicate it was not instituted until 1969. In any case, the OVG trademark was apparently not actually embossed on the bottom of any of this glassware until 1970 or 1971, continuing in use until 1979. I invite readers who have more definitive information on this mark and it’s exact period of use to contact me with more details.

………….Pennsylvania Products Company, Pittsburgh, PA……….. (Note added 12/8/2016): There had been some speculation this mark might indicate the Pfizer pharmaceutical company, but that is incorrect. The “P in a flag” mark has now been positively identified as having been used by the Pennsylvania Products Company of Pittsburgh. This information has come to me from Lynor Lisi, who sent photos showing lettering on a cardboard carton of unused “NOS” emerald green bottles bearing the “P in flag” mark on their bases. The carton appeared to have been manufactured (or packed) in June of 1971. The bottles were actually manufactured by Owens-Illinois at their Fairmont, West Virginia plant. Apparently Pennsylvania Products Co. distributed vials, medicinal and laboratory bottles at the wholesale level, selling products actually made by O-I. There are listings on the web that indicate PGPC is still in business, but the exact timeline of business activity between 1932 and the present is rather murky, and the total period of use of this mark on bottles is unclear. PGPC was evidently in business (to some capacity) as early as 1932, the president of the company (Tunis J. Dykema) receiving a patent for his invention of a combination bottle stopper/rubber dropper in that year. The original patent number is 1843812, the “Re-issue” number is #19520 which can be found on “Google Patents” as RE19520. That patent number is usually, if not always, marked on the base of the bottles along with the P marking.

The design is somewhat similar to a toothpick holder in the EAPG pattern “Kanawha” made by Riverside Company, Wellsburg, WV in the very early 1900s. Another toothpick holder with a very similar, but not identical, design was made by L. E. Smith Company, known under the pattern name “Dominion”. The upper rim has nine “scallops” or “petals”. These pieces were evidently produced for the Paragon Products Corporation based in Oshkosh, WI. A very similar piece, if not identical (seen in several frosted colors) is found marked only “No. 737” on the base and it matches up with a toothpick (designated as mold number 737) shown in a Brooke Company (of Wellsburg, WV) catalog. See catalog pages showing votives made by Brooke on this page from the Fairylampclub.com Aug 2001 newsletter, pages 8-9: Fairylampclub Aug 2001 Newsletter . The “Paragon” candle holders were probably made in the 1970s or 1980s. Another “tulip” style with four “petals” is marked “No. 239”. There is little information available but Paragon Candles seems to have been a maker and distributor of wax candles and candle-related items for quite some time, beginning in the late 1930s or early 1940s. This company was apparently a parent company (or affiliated firm) with Victrylite Candle Company of Oshkosh. Some other items sold by Victrylite were marked “Made in Italy” so it is possible some of these votive candle holders were also made by an unidentified company in Italy.

Although the spring water in that area had been known and drank by European settlers as early as the mid-1800s, if not before, it wasn’t until 1913 that a modern bottling plant was built in the vicinity, and soon after the water was being bottled in tremendous quantity. Many of the earlier “ Water” bottles were made in a characteristic light green colored and are products of Root Company of Terre Haute, IN , but some of the later ones were made by Owens-Illinois. Other companies probably also made some of these bottles over the years. There are several different sizes of bottles found. The base of the bottle pictures the representation of “ ”, the Roman mythological god of the underworld. The picture is often interpreted as a “devil” with horns and a forked tail. Typically the word “ ” is placed below the graphic. There is some variability in the exact design of the image, as many different molds were made for this type of bottle.

R within a “Sun” or Sunburst……………. This mark is seen on the base of several styles of bottles, including cylindrical bottles that, judging from the style, probably contained floor wax, furniture polish or a similar product. The mark is also seen on bottles with the accompanying markings “DES PAT” and “94,231”, referring to a bottle design patent that was issued to Glenn A. Mengle on January 1, 1935, and assigned to Wizard, Inc, of Chicago, Illinois. Some later bottles indicated they had contained products made / sold by Midway Chemical Company of Chicago. A rectangular bottle containing a brand of multi-purpose oil (“Radiant Machine Oil”) has been recorded, made by Midway Chemical. The bottle package shows the design of the word “Radiant” placed within a sunburst. These bottles have been made by Owens-Illinois Company and possibly Brockway Company, and presumably date from the 1935 to mid-1950s era. Although the Mengle connection is referring to a “ patent ” of a bottle design, this “R in a sunburst” logo would assumedly be classed as a “ trademark “, of which specific detailed information has not been found as yet, at least to my knowledge. It seems that the “R in a sun” has been used as a trademark on a number of different household/cleaning-related products sold through both Wizard and Midway over the years.

……………………embossed marking on face of strapside flask. Made at the North Wheeling Works (dba Geo. W. Robinson), Wheeling, West Virginia (c. 1860s- c.1910). Exact time frame when these flasks were made is open to question, but they may date from sometime during the 1865-1875 period. Some sources (i.e. McKearin) indicate the works were in business as early as 1860. But in the earlier years window was the predominate product; later on they switched to making primarily bottles. George W. Robinson was the owner/manager of the works sometime in the 1860s/1870s. An 1879 reference ( History of the Pan-Handle , published by J. A. Caldwell) mentions “Mr. Robinson” was involved in early years, but indicates the works had just recently began operating with a new company (group of owners) under the name “North Wheeling Company”, for a “short time”, meaning perhaps since 1877 or 1878(?). The last mention I can find of this operation is from c. 1910 when young boys were striking at the factory.

(1882-1885); Kelley, Reed & Co. (1886-1887); Eugene Reed & Co. (1888-1889); E. P. Reed & Co. (1890-1894); Rochester Works (1895-1898); F. E. Reed Company/Works (1899-1900); Rochester Works (1901-1908); F. E. Reed & Co. (or F. E. Reed Co.) (1909-1927); Reed Co. (1927-1946); and Reed Co., Inc. (1947-1956). Several marks were used at various times by this factory, and the exact period of time that each mark was used is not entirely certain. Known marks include “Reed”, “F.E.R.”, “F. E. R. G. Co.”, “R in a triangle”, and “ ”. Some blob beer bottles are known with the marking “Rochester NY Works” embossed in a circle on the base. The full factory name could conceivably have been embossed on bottles dating from anytime within the 1862-1908 time frame. After a time of inactivity, the Reed Company plant at Rochester was purchased by Castle-Hanson Corporation in 1959, and the “C-H” mark was used for some period of time thereafter. Later, Leone Industries, based in Bridgeton, New Jersey, purchased the plant and their “L in an unconnected square” mark was used on ware produced at Rochester as well as Bridgeton. Exact dates of later operations of this factory are unclear. (See “R in a triangle”, “C-H”, and “L in an unconnected square” marks).

S & L C (could be either “C S & L” or “S & C L”) ……………… unidentified mark seen on base of handmade black ale bottles that are almost certainly products of Great Britain. The exact order of the letters is unclear, although I presume the letters are to be read in a clockwise direction, beginning with “S”. There is a raised bump or dot (mamelon) in the center of the base, often seen on these types of bottles. This mark probably dates from sometime in the 1860s-1890s. I know of only two reports of this mark (so far), so presumably the factory was rather obscure or short-lived, or else they didn’t mark most of their bottle production. Other black ale bottles made in Great Britain (and exported to other countries including the US) that are somewhat similar in general “look” would include those marked “C W & Co”, “G W & J”, “Dixon & Co.”, “M C G Y” and “Woolfall Manchester”. The great majority of British black ale, stout and wine bottles of this general type are unmarked. The “black ” is in most cases a very dark olive amber or olive green color, but appears nearly black in reflected light. The bottles were typically made in a three-piece mold, and often have a rather crudely applied lip.

Scottish-born Pittsburgh businessman William Kelman purchased the property in 2005 and hoped to revitalize the works, and the factory was apparently able to continue making some more for a while, but evidently shut down permanently sometime in 2007 (online sources are contradictory or unclear – can you tell me when the last was ACTUALLY manufactured there?).

S. F. (on skirt of CD 102 and CD 112 style “pony” telephone insulators)…………………….. unknown meaning.

These insulators appear to date (from their style and “look”) from sometime in the 1900-1915 period, and are found in shades of aqua and green. Many have been found in the western parts of the United States. The most plausible theory points to Fobes Supply Company, an electrical supply company operating in the Western states in the early 1900s. But if that were the case, why isn’t the embossing “F.

Reportedly used on machine-made bottles after c. 1920, per Julian Toulouse in “ Bottle Makers and their Marks “, 1971. * Sterling Company, Lapel, Indiana (1914-1950). Hand-blown bottles were produced from 1914 to 1918, at which time semi-automatic production was introduced. Sterling operated as the “Sterling Division” of the Warfield Company of Chicago from about 1940 until 1950. Brockway Company bought the Sterling factory in 1950. * Southern Company (seen on base of crown-lip soda bottle embossed “Crystal Bottling Works, Tucson, Ariz.)……………………. the meaning of this particular “ ” is open to question, but researcher Bill Lockhart believes it may have been used by Southern Company, Vernon, CA, on a few soda bottles. (Also see “S in a diamond”, below). For more information, see this article from Bill Lockhart et al: The Mysterious Letter S – SHA.org. * Sneath Company, Tiffin, Ohio (1892-1894) and Hartford City, Indiana (1894-1952). This particular “ ” mark is most often seen on certain types of glassware including kitchen canisters (storage jars). Sneath operated for a short time in Tiffin but a new plant was built and started production in September of 1894. Sneath made a wide variety of types of glassware, including kerosene lamp globes, semaphore signal globes and “Hoosier cabinet” jars such as spice jars, coffee and tea jars, salt and pepper sets, etc. The “Hoosier cabinet” jars were especially popular in the 1920s and 1930s. For a much more comprehensive article on Sneath, see the Wikipedia article here: Sneath Company – Wikipedia article * ALSO: An “S inside a circle” mark has been seen on the bottom of a white milk wide-mouth jar/bottle, possibly connected with the “TANG” brand orange flavored powdered drink mix, and dating from the early 1970s. This piece features a daisy motif encircling the shoulder area of the bottle. The S mark in this case has not been identified with certainty, and was used long after the other companies listed above were out of business.

……………… as seen on the base of small amber pharmaceutical bottle. The Sandoz company was founded at Basel, Switzerland in 1886 by Alfred Kern and Edouard Sandoz, at first producing color dyes but by 1895 their first pharmaceutical products were being sold. The company produced many pharmaceutical products during the 20th century, including those made to treat migraine headaches. Their most well-known product was probably the drug LSD, first made in 1938 but sold by Sandoz from 1947 to 1965 under the brand name DELYSID. The company merged with Ciba-Geigy in 1996 to become Novartis. By 2023 Sandoz again became a “standalone” company, operating under its former name. The brand name Sandoz is now used for a variety of “generic” drugs. Some more basic info is here – SANDOZ – Wikipedia article. The photo above shows the mark embossed on the base of an amber bottle about 2 and 3/4ths inches in height. The “S in a triangle” trademark was used for many years on their bottle bases and lids. I don’t have info on the exact time period of use for the mark. This particular bottle was found in a dumpsite that was closed in 1952, and the bottle likely dates from the 1930s- early 1950s. The actual glassmaker is unknown, presumably made in Switzerland or another country in Western Europe. With no label, the former contents are unknown but it may have held a product such as Scilleren or Gynergen.

(Thanks to Mark Newton for this info). If the “S” is on a clear bottle, or on a machine-made bottle, that would indicate another maker. Note : as with the great majority of cases involving soda bottles of the late 19th and early twentieth century, if the bottle base has just a large letter, such as S (or any letter, or initials comprised of 2 or more letters) and this corresponds to the initials of the bottling company name embossed on the front of the bottle, that would serve as a self-explanatory meaning, and nearly always does not indicate the manufacturer.

A trademark for the name “ ” was issued on November 1, 1931 to the Samuel Mallinger Company of Pittsburgh, PA. The company claimed actual use since August 1, 1931. According to Creswick, the Knox Bottle Company, Inc, of Marienville, PA was the primary manufacturer of these jars, but other possible makers included Glenshaw Company, Glenshaw, PA. and the Ball Bros Company , Muncie, IN.

……………………… , San Francisco, California (c.1865-1876). Full name is seen spelled out on the front of some “squat” soda bottles, circa mid-1870s.

Operated until 1876 when this company merged with Pacific Works to form San Francisco & Pacific Works. A photograph from the 1870s (courtesy of Alexander Kerr) is shown on page 289 of “The Fruit Jar Works” by Alice Creswick (1995), and the photo shows a large display of wares made by this company including fruit jars, wine bottles, beer, ale, whiskey, soda bottles, pickle jars, medicine bottles, and many demijohns and carboys with & without wicker coverings. Most of these bottles probably were not marked, or marked with the user instead of the maker. Some are believed to be identified by a characteristic star marking on the base (See “Star” entries on this page).

…………………. Swayzee Company, Swayzee, Indiana (1895-1906). This “S G Co” monogram is seen embossed on the front of certain “Mason’s Patent Nov 30 1858” type fruit jars. The emblem is placed between the words “MASON’S” and “PATENT”. The variant usually found is listed as jar #1974 in the “Red Book” price guide used by antique fruit jar collectors. The jars are typically marked on the bottom with a three-digit number (a mold identifier). The letters comprising the monogram may be difficult to identify and are often misunderstood by collectors. This marking was attributed to Safe Company, Bowling Green, Ohio; Redkey, Indiana; later, Upland, Indiana, by author Julian Toulouse. Since the publication of his books (1968, 1971), wooden shipping crates have been found with illustrations of a Mason Patent style jar with the SGCO monogram – identifying it beyond doubt to have actually been used by Swayzee. (Although the monogram on the shipping crates is not absolutely identical to the monogram on the jars, it is very similar, and I don’t think the jars should be attributed, because of that difference, to any other company such as Safe Co. Artists doing work for packing crates, letterheads, patent records, etc., in the 1800s often took some liberties with the exact appearance of a design or trademark for a business). All “SGCO monogram” Mason’s Patent NOV 30TH 1858″ jars are handmade with ground lips, which would identify them as early Swayzee production, circa 1895-1898. Since the “Swayzee Improved Mason” jars (all machine-made) were produced beginning around 1899, that jar was promoted as an “improvement” on a previously made jar by Swayzee. And the SGCO monogrammed Mason jars fit that bill quite well.

……… (on the front of “WARRANTED FLASK / UNION MADE” flasks)………………… this bottle (made in a range of sizes) is attributed to the Star Company of Medford, New Jersey (also known as Medford Works), and is fairly commonly seen in the Eastern states of the US. According to Adeline Pepper in her reference book The Gaffers of New Jersey (1971), page 175 , the Star Company operated (under that name) from 1894 to 1923 and made a variety of bottles. Glassworks on the site of Star evidently operated as far back as 1825, at first making window . This historical plaque/marker (link below) gives “1850-1923” as the years for Star.

This bottle closely resembles the perfume bottles marked “Lubin” and “Hoyt’s”. Many other colorless bottles of various types have also been recorded, including small “generic” druggist bottles, and the most likely manufacturer appears to be Tibby Brothers. However, virtually all confirmed bottles made by Tibby were produced in colorless (or nearly so) . The Tibby Bros. factory called itself a “flint ” company which, for the most part, typically meant an operation that produced clear . However there are a few known mouthblown amber bottles with a “T” mark on the base, and the maker in those cases is uncertain. One example is a cylindrical amber medicine/packer style bottle with tooled lip, measuring 5 & 1/8th inches tall.

……………………………… United Bottle Manufacturers, Limited (large conglomerate of many factories in the United Kingdom). This mark dates from 1913 to about 1968 and is found on the bases of innumerable bottles of many styles and sizes that were made in Great Britain. UGB included factories located at Ravenhead, St. Helens; Sherdley, St. Helens; Portobello, Scotland; Charlton, London; Shettleston, Scotland; Castleford, Yorkshire; Harlow, Essex; New Cross, London; Brimsdown, London; Kinghorn, Scotland; Alloa, Scotland and Peasely, St. Helens. The history is confusing and some factory locations operated for a very long time but others were relatively short-lived.

U (symbol which vaguely resembles the letter “U” , a horseshoe, or an upside-down version of the Greek letter “Omega”…………………… Ardagh Group (pronounced AHR -DAW), originally based in Dublin, Ireland, with headquarters now based in Luxembourg, with many bottle manufacturing plants across Europe including Germany, Denmark, United Kingdom, Poland, Netherlands, Italy and Sweden. On most bottles, a number is placed to the immediate right, and that number denotes the factory that produced the . (For instance “U 31” seen on the heel of a Heineken green beer bottle indicates production at Ardagh’s bottle factory at Moerdijk, Netherlands). Ardagh began as the Irish Bottle Company, Ltd in 1932, changing the name to Ardagh PLC in 1989. NOTE: In the year 2014, Ardagh Group acquired the former Saint Gobain / Verallia factories in the United States, and this mark has since come into use on jars and bottles made at those plants. Thirteen container plants in the US are currently (as of 2021) under Ardagh Group ownership and it is my understanding they are all using this logo on their container glassware. (See the list of those 13 plant locations on the Ball Bros. Manufacturing Company page ). The logo design is an abstract representation of a chalice, loosely patterned after the celebrated ancient Ardagh Chalice found in Ireland. The mark usually appears on the lower “heel” area of containers but sometimes on the base. According to trademarkia.com, this logo was officially registered as of November 11, 2014.

…………………. if a machine-made bottle marked with a “U” ( no serifs ) on the base was made for an end user company based in or around the New Orleans area, the mark would almost certainly stand for the Underwood Company, with factories at New Orleans (Harahan), Louisiana (1956- Oct. 1979?) and Mineral Wells, Mississippi (Nov. 1969- late 1974 or early 1975??). (Mineral Wells is an unincorporated community in the southern part of the metro Memphis, Tennessee area). Two clear machine-made bottle types confirmed to be from this maker include certain examples of the Brer Rabbit brand molasses bottles, and some Baumer Foods, Inc. bottles that contained their Crystal Hot Sauce brand (see base photo above). A bottle style that typically held Karo brand syrup – probably dating no earlier than the late 1950s or ’60s – was seen on ebay with this mark on the base. This mark is quite scarce and not commonly seen – probably because most bottles made by Underwood were “generic” utility types, and usually discarded soon after use. There are surely many of them to be found in refuse dumps of that time period, probably most commonly in the south-central US. If anyone has more exact information concerning the last day of bottle production at either the Harahan or the Mineral Wells factory locations, please contact me and I will edit this entry.

Many of those bottles were made in a vibrant cobalt blue color and appear to be typical of the 1850s-1860s era. I have found conflicting info on the timeline this company was in business.

Most of the containers bearing this mark seem to be relatively recent production, probably from the 1970s-1980s and thereafter. Many types of items have been made including olive oil and vinegar cruets, kitchen canisters, candle holders, “fish” bottles, and other kinds of decorative and household bottles. Many items are found in a characteristic very light greenish-aqua colored similar to the older Coke bottles. If you have information on exactly when this mark was introduced, and what (if any) other marks were previously used by this glassmaker, please let us know!

……………………. West Coast Company, Los Angeles, California (1918-1930). According to Julian Toulouse ( Bottle Makers & Their Marks , 1971, page 536) this company primarily made milk bottles, some being found with this mark on the bottom. (Jelly glasses and tumblers were made before 1921). Toulouse doesn’t mention any other types of bottles that were made. Presumably most of the milk bottles made by West Coast were distributed in CA and the western states of the U.S. However, a tooled-lip, handmade (mouthblown) rectangular prescription bottle in clear (with slight grayish tint) marked “3 OUNCES” on the front was found in the east (Virginia) that bears this mark on the base. (Although the “o” is lower case). Another type of generic druggist bottle of the same basic shape and with the same marking was dug in the Rome, NY area. If another bottle manufacturing company used these initials, which certainly appears likely, it was probably located somewhere in the Eastern part of the United States. One possibility would be a short-lived venture, the Wightman Co-operative Company, Port Allegany, Pennsylvania (1915-1917). At this time, I consider the initials on those prescription bottles to be that of a glassmaker that has not been identified with absolute certainty, but Wightman sounds like it would be a likely candidate. For more info on West Coast Company, see this article from Pete Schulz, Bill Lockhart and the Bottle Research Group: West Coast Company – SHA.org

Wightman Company (1893-1917) / Wightman Bottle & Company (1917-1921). There is also a possibility that some bottles marked with just a “ ” on the bottom are products of Whitney Works, Glassboro, NJ (c. 1875-1918), but that is only a guess! A square, handmade applied-lip aqua pickle bottle that bears a “ ” on the base looks to date from the 1880s or 1890s. Fruit jars with “ ” on the side, and and “L &” faintly visible (removed from the mold) are believed to be Thomas Wightman & Co. products.

……………..Used by at least 2 or 3 companies (or more). Wisconsin Company, Milwaukee, Wisconsin (1881-1886) produced beer bottles with these initials on the base. Those beer bottles are usually found in some shade of amber . A “W G CO” mark is also confirmed on a clear, rectangular mouth-blown druggist bottle, circa 1900. A possibility for the source of the mark in that particular case might be the Wagner Company, Ingalls, Indiana (1895-1908). Company info on Wagner can be found in Dick Roller’s Indiana Factories Notes , page 49. Julian Toulouse states (Thos.) Wightman Company, Parkers Landing, Pennsylvania (he wrote “1900-1930”, but more recent info indicates c. 1893-c. 1921) as the user of “ .” (See “W”). I also suspect that some bottles made by Wormser Company, Pittsburgh, might have carried this mark. Woodbury Company (1893-1920) with three plants located in Indiana (at Parker, Winchester and Shirley) made some machine-made milk bottles with “ ” on them, typically on the heel, according to research by Bill Lockhart.

This mark is seen on the bottoms of many laboratory, chemical & drug bottles including very small vials, and has been in use since about 1946. Previously (c. 1901-1946) their typical mark on laboratory bottles was “T.C.W.CO”. (Uncertain on the last year the “W in a circle” mark was used.) In recent decades, Wheaton has expanded with a large line of products catering to the medical / pharmaceutical / scientific world. As far as bottle production, the company produced large quantities of colorful commemorative and decorative bottles, especially in the 1960s, ’70s and ’80s. (See “Wheaton” entry on this page). They manufacture a good percentage of the small “serum bottles” or “vaccine bottles” and sterile injection vials (the small vials used to contain vaccines, etc.) sold in the United States and other countries. Update: Wheaton has gone through a confusing series of reorganizations/mergers and company takeovers within the last few years. As of 2015 Wheaton came under the control of DURAN Group GmbH, later (2017) renamed DWK Life Sciences, of Germany. For a good overview and general outline on Wheaton and its history (primarily up into the 1990s), check out this article: Wheaton Industries – Encyclopedia.com . Also, please see “T. C. W.

…………………… William McCully & Company, Pittsburgh, Pennsylvania (c. 1833- c.1909). Firm operated a number of different glasshouses in the Pittsburgh area over a very long period of time. There were changes over the years concerning the exact persons involved in running operations. The McCully-run bottle-making factories included Phoenix Works, Mastodon Works, and Pittsburgh Works. Several other factories (Sligo Works, Empire Works and perhaps others) apparently made mostly window . The very last McCully-associated factory (Sligo – a window house) closed in about 1909. The history of the McCully operations is very complex, confusing, and discrepancies abound concerning the exact years of operation of the various McCully-owned and/or operated factories. Most bottles marked “Wm. McCully & Co.”, ”, “Wm. McC. & Co”, “Mc.C. & Co”, “McC” and other minor variations probably date sometime between 1860 and 1895 .

W (somewhat flattened “W” trademark, seen on the base of miniature sampler liquor bottle in amber, shown above)………………… Wisthoff & Co. Glashütten, Essen, Germany. A drawing of this mark is shown in Bottle Makers and their Marks (Toulouse, 1971) on page 583. At a quick glance it might resemble a simplified bird with wings outstretched during flight. Please see photo of the mark here. (The “20” is a mold number, and the “M” is a mold mark of uncertain meaning – the M does not stand for a company – as is the case with certain bottles made by other companies such as Maryland Corp.). According to Toulouse, Wisthoff was using this mark in 1965. The mini sampler bottle shown (sometimes called a “nip” or “airplane bottle”) is of uncertain date, possibly from the 1960s-1980s. Wisthoff is now (2023) part of the huge corporation Gerresheimer Glas. The container factory at Essen is shown as “Gerresheimer Essen GmbH” on their website. Not sure when this mark was discontinued (assuming it is no longer in use). If someone knows, please contact us!

………….Westmoreland Company, Grapeville, Pennsylvania (1889-1984). To be more accurate, this maker was known as Westmoreland Specialty Company from 1889 to 1924, being officially renamed in 1924 or early in 1925. The “W over G” monogram is seen most commonly on high-quality colored and opaque pressed and pattern , including tableware, novelties, hen-on-nest covered dishes, etc. Westmoreland produced huge quantities of white milk tableware during the 1940s and 1950s, much of it avidly collected today. A lot of their earlier ware was not marked. This particular mark reportedly dates from 1949 to 1984 . (See also “W in a keystone”, an earlier mark used by Westmoreland). Caution: This mark is also seen on some more recent items, such as hen-on-nest dishes, that were made after 1984 but produced from older molds which have since been sold to other making companies.

……………… Crystal, City, Ireland (1783-1853 and 1947-to the present) ………………… The original factory opened in 1783, founded by entrepreneurs William and George Penrose. The glassworks specialized in producing extremely high quality handmade blown and cut crystal (leaded ) including wine glasses, goblets, tumblers, bowls, decanters and other items. The company gained a reputation for extremely well-made, intricately cut glassware. The company continued for about 70 years until it closed down after undergoing financial problems in 1853. Then, for nearly one hundred years no was produced, but the name was resurrected in 1947 when two Czech immigrants (Kael Bacik and Miroslav Havel) started a new operation at . They strived to create new handmade with the look and quality of the original cut glassware from the 17th and 18th centuries. The “new” Crystal glassworks is still operating as of 2026, although the great majority of is now no longer made in Ireland, but in other countries including Slovenia, Czech Republic, Hungary, and Germany. Most of the crystal made by before the 1980s was not permanently marked. Marking commenced sometime in the 1980s and the name appears (often rather hard to see) etched underneath on the base. However, some of the newer is also not marked. Most of the more recent production carries a sticker and/or permanent mark incorporating a seahorse motif. “ ” is considered (by some) almost as a “generic” name for very high quality cut crystal.

Wittemann Bros. was a wholesaler/distributor of supplies for the beer and soda bottling industry, and also sold other products such as postcards. They were not a manufacturer, so would have had contracts with bottle makers to supply bottles marked with their initials. The manufacturer(s) of the WB-monogram bottles is unidentified, but likely a firm in the NY/NJ area. More info on Wittemann can be found here: Other W Marks – SHA.org

………………………Wheaton Company / Wheaton Industries, Millville, New Jersey (1888- to present). (Now known under DWK Life Sciences – since 2017). Producer of many reproduction bottles, Avon cosmetic, cologne, decorator bottles and a wide variety of other glassware. Also please see “W” (stylized), “W in a circle” and “T.C.W. Co.”. entries. The Wheaton enterprises have had a rather complex history since 1888. After several restructurings, buyouts and renamings, Wheaton Industries (DWK Life Sciences) has diversified and is primarily a manufacturer of many lines of pharmaceutical/scientific products, including their “old standbys”- serum bottles, used to contain vaccines and other pharmaceutical products. Many if not most of the reproduction bottles, “fantasy” bottles, decorative figural flasks and containers marked “WHEATON” or “WHEATON NJ” on the bottom were made during the 1960s – 1980s. The “Cape Cod” ruby red line of tableware produced for Avon was manufactured over a period of many years: 1975-1993. (See the page on Avon bottles for a picture of these Cape Cod style goblets). Some items are marked “Nuline”, and many of the repro/fantasy bottles have an “imitation” pontil mark on the bottom, which looks like a depressed area in the , sometimes vaguely shaped like the outline of a state such as Iowa or Ohio! Some items such as canister sets are marked with a “stylized W” (see entry above on this page) and those were issued under the name “Wheaton Fine Glassware” in the 1980-1984 period.

…………….. , Glassboro, New Jersey (c. 1836-1918). Claiming an “ancestry” dating back to the late 1770s, as early as 1836 this firm operated under the name “Whitney Brothers”, although in later years (by 1875, if not before) it was known as “ ”. The “official” name of the firm became “ ” in 1887 (according to Adeline Pepper, The Gaffers of New Jersey – 1971, page 42), although ads dating from 1875 show both versions of the factory name within the same ad. This works made many types of bottles, including the famous original “BOOZ” bottles shaped like a cabin, the Drake bitters bottles, and many others. Various bottles are marked “ ” in a circle on the base, and these may date after 1887, although I feel that some might date before that year, since the timeline as to when the name was first actually embossed on their bottles seems rather “fuzzy”. In 1918 this factory became a part of the Owens Bottle Company. In 1929, after the forming of Owens-Illinois Co, the plant became O-I plant #8.

……………… Willington Company/Willington Works, West Willington, Connecticut (1814-1872). Full name seen on several figured flasks, as well as embossed in a circle (as “Willington Works”) on the base of cylinder whiskey bottles. The flasks might date from the late 1840s into the 1850s or 1860s. The Willington glassworks is also famous for their much-hyped “Gothic cathedral” pickle jars (pickle bottles). However, many, if not most, bottle manufacturers along the US East coast and some in the Midwest made similar ornately designed square pickle bottles, of a variety of designs, so sometimes a particular bottle may be presented as “possibly Willington” without positive confirmation of its provenance. No Willington Cathedral pickle jars were actually marked with that glasshouse identification.

……………brand name seen on the base of many cold cream containers.

Most of the typical white milk cold cream jars with the marking on the base seem to date from the 1920s-1950s era, but I don’t know exactly when they were first made, or how late they were produced. I have also seen “ ” embossed on a “beach ” bottle base accompanied by the makers mark “BALL” in cursive lettering (standing for Ball Bros Company).

……………………. As a solitary mark, often embossed rather crudely in large bold strokes, seenon the bases of many older hand blown bottles and jars, most from the 1850s-1910 period. I believe this is an example of a mold identifying mark. It might have served the purpose of identifying a particular mold in use at the factory (especially when a number of virtually identical molds were being used simultaneously) in place of a number. In some cases it may be equivalent to a “shop number” or “shop letter”, identifying the output of a specific “shop” (group of glassworkers within the factory) assigned to produce a certain item. In such cases the worker was paid according to the output of a particular shop. There are many other marks known, including geometric shapes (triangle, diamond, heart, square), star, hash mark/tic-tac-toe mark/pound sign/number sign, spade, clover, Maltese cross, etc,) seen especially on the bases of 1870s-1890s era fruit jars, that might have served a similar purpose: equivalent to a mold number or a shop number. In some cases a mark may have been meant only as a decorative design added to the mold. At this late date, it’s difficult to know with 100% certainty the purpose of any particular mark or emblem of this type. Also, please see my entries on “Star” markings.
