Southern Song Dynasty Blue Glazed water bowl with Dragon Decorations

A blue-glazed water bowl from the Southern Song dynasty.
A water urn is a tool used to transfer water to a suzuri, and since the side is decorated with a three-dimensional dragon, it is thought that it was used by aristocrats who wrote letters.
The outside is covered with a greenish blue glaze up to the side of the bottom and the whole is finely crackle-glazed, giving it a beautiful glass-like shading and luster.

There is no conspicuous flaws.There is a small aged deterioration on the surface, but overall it is luster and in good condition.
