A sake cup fired in the Tsuboya kiln at the end of the Ryukyu Kingdom. The curvy shape with opened lip is moulded with reddish-brown clay. A graceful transparent glaze is applied to the entire body over a white slip.

The white slip technique began to use in earnest at Tsuboya kilns in the first half of the 19th century and has been a representative technique of the kiln until now. This piece has been handed down as a sake cup for many years, and the layers of cloud-like stains occurred, making the lustrous surface even more tasteful.

There are no conspicuous flaws other than a very minor glaze flaking on the lip. It comes with a box.
