This is a ceramic piece by an unknown artist. It is a type of Tanegashima-yaki pottery, with a subdued color and a sense of weight. The texture fits comfortably in the hand, and has a unique luster characteristic of unglazed pottery. Some glaze is applied, but Tanegashima-yaki is made using soil rich in iron, and it is said that a unique luster is created even with unglazed pottery, so unglazed is the basic style. Diameter: Approximately 8 cm Height: Approximately 15 cm Mouth width (hole): Approximately 1 cm I received this from an acquaintance, but I am selling it because I have a similar item.
