Tenmoku tea bowl is a pottery that is fired by using iron glaze called tenmoku glaze. It was used for serving tea to a god and noble. The tea bowl was originally imported from China in the Kamakura period (12th-14th century); thereafter, it was 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 hip and turns into a black color. The base clay shows its reddish- brown coarse texture at the bottom.
