This small ceramic dish is thrown on the wheel from smooth stoneware. Glazed in matte black glaze and fired to 2340º F for a strong vitrified finish. Feather and platinum splash are then added and dish is fired again to a lower temperature. Measures approximately 4 7/8" wide by 1 1/8" high. Remember these are handmade and each piece is unique and may vary slightly in size. I use all non toxic materials so dish is completely food safe. Because of the platinum feather and splash dish is not safe for the microwave and hand washing is recommended.
