The items are made of sandstone unique to Hasami region, mixing sand and rocks with Amakusa porcelain stone mined from Amakusa islands. This porcelain clay ensures durability and deep nuanced expressions are created by the iron in the sandstone reacting with the glaze. Rough texture of the clay peeks out at the bottom under the calm color glazing, and the bottom edges give a sharp impression reminiscent of quarried stone.
