Excavated from Hisae, Nakanoto Town, Kashima County, Ishikawa Prefecture
13th century
Height 28.5cm, Body diameter 16.0cm, Bottom diameter 9.0cm
Although the top spout is regrettably missing, this is the only known piece of Suzu ware jovin (purification vase). There are many examples of jovens in Heian-period japanned porcelain, but none have been seen in medieval ceramics.
It is wheel-thrown and has a flat bottom. It has a single band on the shoulder. The spout attached to the shoulder has lost its original shape and shows a degenerate form like the spout of an earthenware bottle.
The body is decorated with a five-tiered wavy pattern in a comb-like pattern. It is thought to have been made around the end of the 13th century. It is a type of Buddhist ware and one of the representative pieces of Suzu ware.
