1824 saw the opening of Dummer's Glass Works on Communipaw Cove, west of Washington street and south of Morris Canal. The site is now occupied by the sugar house. The flint glass of these works, started in 1824, has never been excelled. In 1825 the Jersey Porcelain and Earthen Ware Company was incorporated in the Town of Jersey, County of Bergen. Under the Act of Legislature George Dummer, Timothy Dewey, Henry Post, Jr., William W. Shirley and Robert Abbatt, Jr., were named as incorporators. In 1826, at the exhibition of the Franklin Institute in Philadelphia, a silver medal was awarded to this pottery for the "best china from American materials." This pottery is exceedingly interesting from the fact that it was the pioneer in America along several lines; it was the first to manufacture porcelain, for which French workmen had been brought over. For three years they manufactured porcelain of good body and excellent glaze. About 1829 Messrs. D. and J. Henderson bought the works and manufactured flint stone ware of superior quality. In 1833 David Henderson organized the "American Pottery Manufacturing Company," for the purpose of manufacturing various kinds of pottery. By Act of Assembly of January 18th, 1833, the following commissioners were appointed to solicit stock subscriptions: David Henderson, John V. B. Varick, Robert Gilchrist, J. Dickinson Miller, of Jersey City, and Edward Cook, George Tingle and J. Steele, of New York. During the seven years following there was made at this pottery the first successful competition with England in the manufacture of a buff or cream colored ware of excellent quality, and for the first time in America was adopted the English method of printing transfer in decoration. During the Presidential campaign of 1840 there was made here a large eight-sided water pitcher of cream colored ware; on the four front panels were black under glaze prints of a log cabin above the legend "The Ohio Farmer," and below a portrait bust of W. H. Harrison, with the American Eagle. The mark on the bottom in black under glaze was a flag with the inscription, "American Pottery Manufacturing Company, Jersey City."
