Tenmoku tea bowls are ceramic tea bowls that are fired by using an iron glaze called a tenmoku glaze. They were originally imported from China for serving tea to gods or noble people in the Kamakura period (12th-14th century). Thereafter, they were also produced in Japan.
This tea bowl has reddish-brown striations of the glaze called “nogime” from the thin lip to the thick inner bottom. The glaze builds up and makes a comma-shaped pool at the bottom. The glaze on the outer surface is a bronze color, which builds up at the waist and turns into a black color. The base clay shows its reddish- brown coarse texture from the hip to the bottom.
