Here is a sweeping survey of the popular spongeware ceramics produced in Scotland, England, Europe, and North America for one hundred years, illustrated with over 975 color photographs. Often associated with Pennsylvania German folk art, these tablewares, serving pieces, tea sets, childrens sets, and vases are decorated in colorful patterns achieved primarily through the simple, yet engaging, sponge-printing technique. Included are a thorough definition of spongeware, identifications of the patterns and potters, their marks, and a bibliography. Current market values are provided in the captions.
