It is a Tobe ware wine bottle made in Tobe-cho, Ehime prefecture. From the anecdote that Tobe ware did not break even when thrown together in a quarrel between husband and wife, it is a tough and durable porcelain that is also called a "Quarrel ware". One of the features of Tobe porcelain, the contrast painted in white porcelain and indigo blue, makes it simple, beautiful and clean.
The shape of the streamlined body and cork stopper is also lovely as an object. A bottle with a stable form can be used as a vase without the stopper.
Ceramics made in Tobe-cho, Ehime Prefecture, originated in 1775. On the thick and thick white porcelain, a hand-painted blue pattern called gosu is drawn. Tableware and vases are often produced as they are durable, hard and heavy. They are hard to crack or chip even when handled roughly. They are also designated as national traditional crafts and intangible cultural properties in Ehime Prefecture.
