A Yamachawan (unglazed tableware produced in Japan’s medieval period) excavated in Miyoshi City, Aichi Prefecture. It is from Sanage Kiln, one of oldest kilns in Japan, inferred by its rich natural glaze, inverted trapezoidal shape, and base missing mark on the bottom, besides excavation site. However, there was a migration of Yamachawan’s potters from Sanage area to Seto area in the middle of Kamakura period (1185-1333), and the technique and style was also transmitted in the Seto ware at that time.

The milky natural glaze derived from the pine wood ashes, like tides on the foreshore, as if it bespeaks a new wave that had surged into the ceramic history of “Seto”, (literally means the door of shore) in the 13 century.

There is an earthy odor, but there are no notable defects and the condition is good.
