My Deco Plates are hand built with white earthenware clay and fired three times with a maximum temperature of 1950 degrees. Their surface techniques and materials include underglaze, slip trailing, wax, sgraffito, Mishima, glaze and ceramic decals. They double as purely decorative pieces or as serving plates for light snacks and appetizers. Hand washing is recommended. These are hand made and each will vary slightly. Dimensions: 13.75" x 9"  rectangle
