Inquiries regarding this work


Mumyoi-yaki is a style of ceramics employing unique reddish clays extracted from the gold and silver mines of Sado Island in Niigata Prefecture.
In the neriage technique, several dozen layers of different colors of clay are piled up in such a way that when the clay is cut into round slices, the cross-sections form images of flowers, a huge number of which are assembled to form a large dish. This is then fired unglazed at a high temperature. It takes approximately three months to complete one of these pieces.
