A name derived from the tongue of an ox.
A tool used in wheel-thrown molding. It is mainly used to make plates, bowls, and pots, and is apparently used by potters with roots in Korean pottery in the western Japan region of Hagiyaki in Yamaguchi Prefecture.
It stretches and shapes the clay during molding, and most importantly, it tightens and shapes the clay with the belly of the shaft, tightening the clay that cannot be tightened by hand or finger.
The mirrors inside the prospective pots and today’s “tea pits” are remnants of this process.
