Bowl with golden-brown streaks on a black ground

This glaze, the "hare's-fur" (tuhao) glaze developed in the Song, is distinctive for its dark brown streaks. As one of the jian potters' special productions, the glaze was also attempted by other kilns. Chan (Zen) monks who came to China from Japan during the thirteenth century introduced this jian glaze to Japan, where it became the beloved temmoku produced at many kilns in Japan. Surveys filed in Jianyang county since the 1960s have exposed a large number of kiln remains, and scientific tests have focused on hare's-fur glaze since the 1980s. The slightly curved profile of the mouth is a characteristic nuance of jian bowls.
