 From the latter half of the 14th century, small jars in the shape of a wide-mouthed arithmetic sphere, which is a smaller version of a large jar, began to appear. In Tokoname, they are called “fushiki,” after the name given by Rikyu, but their original purpose is not clear. There are quite a few examples found in medieval cemeteries as bone ware. This vessel is an early example of such a vessel, and has a one-sided spout on a part of the mouth rim.
