Instructions
Examine the base. Almost all Staffordshire china has some kind of manufacturer's mark. Big names to look out for are Minton, Wedgwood, Spode and Doulton. They all employed clear, easily legible back stamps.
Be vigilant for wares marked with a series of initials or an emblem, with another single initial underneath. Smaller Staffordshire firms often marked their products in this way, with the single initial standing for the town of origin. To research these initials, go to the library and consult a reference book such as "The Encyclopedia of British Pottery and Porcelain Marks." You will find the initials listed alphabetically among the general entries. Emblems are usually dealt with in an appendix. The encyclopedia's entry will then confirm whether or not the mark is indeed that of a Staffordshire manufacturer.
Go online after following these steps and visit one of the many excellent websites devoted to Staffordshire china. (See Resources.) By following the links you will be able to learn more about individual Staffordshire factories and their various marks, as well as hopefully discovering more about your own item.
