YAMACHAWAN（MOUNTAIN TEA BOWL）, Ko-Tokoname（fragment）, Heian Period（794–1185CE）

This piece is a fragment of a Yamachawan (mountain tea bowl) from the late Heian period to the early Kamakura period, crafted in the ancient Tokoname style. The Yamachawan emerged in the late Heian period (late 11th century) and was produced for approximately 400 years until the early Sengoku period (late 15th century). Characterized by its unglazed, rustic aesthetic, this bowl was created during a time when the mass production of glazed ceramics was transforming high-end wares into everyday items. This particular example is relatively early in the Yamachawan lineage, exhibiting a very hard-fired body. The rim shows signs of wear, becoming rounded and fragile, while the interior has diminished and developed a small hole. It would make a charming addition to a bonsai display.
