Japanese Tea Cup, Kasama-Yaki drinkware Please feel free to reach out with any questions :) This very unique style will make your tea or espresso stand out. Unlike most other firing methods, the kiln of artisan Masami Taniguchi smokes the cups, which leads to an amazing blueish & rough finish. Prime fired porcelain cups are imported from Hasami, & a few layers of a special glaze is applied on them. Kasama-yaki has its roots in the 18th century & grew to one of the bigger pottery-producing regions in the Kanto area. The Kasama-yaki cups may be used in the dishwasher. Made in: Hasami, Japan.
