Seihakuji (blue-white porcelain), known in English as celadon, is produced using porcelain clay made from white stone. It is pottery that has been biscuit-fired and painted with a glaze containing a small amount of iron, which turns a bluish tint when fired again. This technique originated in China. There is also hakuji (white porcelain), which is painted with a glaze that turns transparent when fired, and seiji (blue porcelain), made with clay containing iron coated with a glaze that turns blue when fired.
