Japanese tenmoku ware ceramic vessel with ribbed handle, short front spout, and wide open top. The thick oil slick glaze stops just short above the foot left in buff.
Tenmoku glaze is made with feldspar, limestone, and iron oxide. The more quickly a piece is cooled, the blacker the glaze will be.
Tenmokus are known for their variability. During their heating and cooling, several factors influence the formation of iron crystals within the glaze. A long firing process and a clay body which is also heavily colored with iron increase the opportunity for iron from the clay to be drawn into the glaze. While the glaze is molten, iron can migrate within the glaze to form surface crystals, as in the “oil spot” glaze, or remain in solution deeper within the glaze for a rich glossy color.
