Fresh water jars for Japanese tea ceremony

Started making some fresh water jars today, based on an old Karatsu Hitoeguchi Mizusashi (一重口水差). Hitoeguchi, or single level rim, don’t have a gallery for a lid, so they almost always are used with lacquer lids. This particular form is a very simple, almost straight sided cylinder with the rim folded over inward to create the lip.

The older piece as well as the new ones shown here, are ita-okoshi, or coiled up from a flat paddled base. After the walls reach the desired height by adding coils, the whole form is paddled to compress the clay, then the rim is finished last. These, still wet, are about 19cm/7.5in wide by 16cm/6.3in high, and weigh about 1200grams/2.6 lbs. The finished pieces will be about 18% smaller.

  1. This is one of the things I like about this particular technique. There is no wasted effort, and what effort that is expended is well spent. The repetetive overlapping coencentric circles created by the anvil are called seikaihajomon (blue ocean wave pattern).
    In larger pots these often get lost in the throwing process, but for smaller things it is possible to keep them fresh.
