An Enmanyin-monzeki Temple sticker accompanies the original wood box for the current bowl and lacquer stand. It is known that after World War II the temple deaccessioned some of their possessions to the Manno Museum of Art, and it is likely that this bowl and stand were part of this group.
The bowl has a very attractive black glaze with a remarkable iridescent sheen which is rarely seen. The formation of patterns on Jian ware bowls depends on the specific oxides of iron that form in firing and to the type of crystals that develop as the glaze cools.
Compare the Jian 'hare's fur' bowl of similar shape and with equally attractive glaze, illustrated in Sekai toji zenshu - Song, vol. 12, 1997, Tokyo, pl. 96-98.
Jian black-glazed bowls were intended primarily for the drinking of tea. The choice of tea during the Song and Jin periods was a pale tea that was whisked to produce a white froth on top. Black-glazed bowls such as the present example became increasingly popular as they showed off the frothy white tea to great advantage.
