About Imperial
“In 1867, Mr. C.S. Cook became the sole proprietor and continued the business up to August, 1873, when the East Trenton Pottery Company was formed and incorporated by an act of the Legislature. Mr. Cook was then chosen President and Treasurer and Mr. W.M. Marshall was made Secretary, both gentlemen serving down to the present time.
Under the new management various alterations, enlargements, improvements and extensions have been made to the works, until now they rank among the foremost in the country. The manufactures are white granite, stone porcelain, C.C. and decorated ware, hotel ware being made a specialty. The premises are 275 x 300 feet in dimensions, on which is erected nine commodious stone and brick buildings, three stories in height.
The engine is of forty-horse power and serves to heat the premises by means of steam pipes. Six kilns are in use and the ware here produced enjoys an excellent reputation throughout the land, Employment is given to one hundred and fifty hands. There are sheds, stables, railroad-switch, canal basin, etc.” — Industries of New Jersey, Trenton, Princeton, Hightstown, Pennington and Hopewell . 1882.
