Kamachi ware was a ceramic of the Yanagawa domain which produced excellent tea utensils in its official kiln.
This unglazed wind furnace is in the shape of chamfered dōan-buro style, supported with three feet. The white patchy pattern shown along the mouth and fire window is the feature of the Kamachi ware. It has two attachments: a trivet and a white mae-kawareke (a piece of earthen ware for stopping sparks from shooting out). The two inscriptions under the fire window read “The master of earthen ware in Kyushu” and “Hōetsu” (the potter’s name).
