Dark brown or blackish Chinese stoneware made for domestic use mainly during the Sung dynasty (960-1279) and into the early 14th century. The stoneware bowls had a lustrous iron or manganese black or brown glaze. This is a Japanese term applied to Chinese bowls used in the tea ceremony until the late 16th century. Some Japanese bowls called temmoku solely on account of their similarity of shape and do not have the glaze. These bowls were highly valued when the tea ceremony first started (15th century) and were classified according to seven types of glazing decoration. In China, this stoneware is called Chien ware.
