3rd Ceramics Black Plate Fourth plate. There are scratches on the back, but this is due to individual variations. Please confirm. Used several times. Please understand that these are used items. Quoted from the HP below: Accidental clouding that floats on black clay Vessels made of black clay that are given expression by applying the glaze called Kosome, which is clouded white. Kosome tends to show expression easily, and a faint gray with a slight clouding of white appears. This is a 3rdceramics original glaze, and because cobalt, a bluish component, is added to the black clay, the glaze reacts to create a bluish-gray finish. The expression of clouding created by chemical reactions and chance is unique, and no two are alike. Size: 24.5cm in diameter
