Slip or colored clay string decoration on Japanese porcelain, in look not unlike 'cake frosting' in which a diluted clay has been used to give the piece a three dimensional appearance. Produced in Japan from the end of the 1800's until the mid 1900's reflecting the western interest in the exotic, of the late 19th century period. Over the time styles and materials changed.
One characteristic type of Japanese export porcelain are thin porcelain tea sets decorated with a women's face in high relief in the bases - see lithophane. This feature together with vivid dragons in moriage was made during the late 1930s into the late 1950s. Most Dragonware pieces are decorated with moriage.
