This is a beautiful Antique Japanese IMARI Plate from the 19th Century. It measures about: Diameter 17 3/4 (45.3 cm) and Height 2 1/4" (5.7 cm). The first Imari Plates were made in the town of Arita and they were exported from the Port of Imari. They were made of white Kaolin clay, discovered in Japan in the early 1600's. The Imari Plates became very popular in Europe in the 19th Century, especially with The Royals. Originally, the plates were blue and iron red on a white background, with rough texture, and unglazed. Then, they were glazed and more colors were added. Decorations included popular Japanese themes: pine, bamboo, plums and other fruits, trees, and flowers. The shapes varied from round, hexagon, octagon, rectangle, and rhombus. Real Imari Plates were never marked with "Imari", except those used in ceremonial weddings. The most valued plates were made before the 20th Century.
