setoguro 瀬戸黒
瀬戸 Seto (place name) · 黒 black
Setoguro (Black Seto) is a Mino ware whose main feature is its jet-black color, produced by a high-iron glaze. Pieces are taken out of the kiln at the height of firing and cooled rapidly in water—a technique also called hikidashiguro (pulled-out black).
Setoguro produces a deep, complex black that can appear to glitter from within. The style is valued in tea ceremony culture for its rich color and soft sheen.
