Jasperware can be made in different ways. Some pieces are made from a solid colored clay with applied raised designs of a contrasting colored clay. Other pieces are made entirely of one color clay with raised decorations that are glazed with a contrasting color. Jasperware is the most famous of the Wedgwood products. It is a nonporous pottery made in many colors. Additional pieces of jasperware may also be listed in the Wedgwood category or under various art potteries.
