It is impossible to obtain any information in England about this dark blue earthenware, or “semi-china,” which was made for so many years in such vast quantities for the American market. The Staffordshire pottery works have all changed owners; the plates from which these wares were printed have all been lost or destroyed; the present owners of the works are ignorant of the existence even of these printed American pieces. There are almost no specimens to be seen in English collections, not even of pieces bearing English views; none for sale in English shops; and even in so exhaustive, extended, and careful a treatise on the ceramic art of Great Britain as that of Mr. Jewitt, he does not speak of them, and evidently is ignorant of the wares, the stamps, and marks. A careful search throughout the Staffordshire region developed absolutely not one fact about these “American historical pieces;” and I may add that a collection of Staffordshire ware bearing both American and English views is now being gathered in America for presentation to the Museum at Burslem, and consequent enlightenment of English collectors and manufacturers. Hence it is plain that each American collector must be a law to himself with regard to marks; or rather, American collectors must unite and form a new table of marks of “American pieces.” I will specify a few that I find on my Staffordshire pieces. A circular impression about an inch in diameter, with an inclosed circle having in the centre the word “Warranted,” and a spread eagle bearing a thunderbolt and laurel leaf. In the quarter-inch ring inclosing this inner disk are the words, in capital letters, “T. Mayer. Stone. Staffordshire.” Accompanying this impressed stamp is always found (on my pieces) a very spirited rendering in dark blue of the American eagle, bearing a laurel branch in his right claw, and a bunch of arrow-like thunderbolts in his left. He measures two and three-quarters inches from tip to tip of wings, has an American shield on his breast, and a ribbon bearing the words “E Pluribus Unum” in his mouth. The lighter, clouded background has thirteen white stars. This mark is the richest in color and best in drawing of any that I have seen. This T. Mayer was, I judge, the Thomas Mayer who had the Dale Hall Staffordshire works from 1829, and of whom Shaw speaks as having made the best specimen of solid earthenware ever produced at that time—a vast table. This stamp and mark are given by neither Chaffers nor Jewitt, nor Phillips and Hooper. The marks E. Mayer, and E. Mayer & Son, are frequently seen. These firms were in existence from 1770 to 1830 in Hanley.
