"Pure and simple. Clean Asian shapes have a thin, elegant feel and sophisticated color palette of subtle celadon and matte black. Porcelain is fired at a very high temperature, with the cooling process creating the beautiful crackling of the glossy glaze. This traditional artistic effect is food safe, though it may discolor when exposed to foods that can potentially stain until it is cleaned in an automatic dishwasher. -Porcelain -Coupe shapes -Celadon crackle glaze interiors -Matte black rims and exteriors -Rinse quickly after use for best results -Dishwasher- and microwave-safe -Made in Japan"
