Tenmoku is a type of iron-glazed stoneware originating in China during the Song Dynasty. It takes its name from the mountain range where it was first produced and, when translated, means "heaven's eye." In the 13th century, tenmoku bowls were introduced to Japan by Buddhist monks returning from their studies in China. They were highly regarded among the Ashikaga shoguns, both warriors and avid tea practitioners, who promoted their use in chanoyu, or Japanese tea ceremony. Since then, tenmoku tea bowls have held their revered position in the history and development of chanoyu. ~2000cranes.com
