Goryeo Small Bottle with Knead Design

A black-glazed bottle from the Goryeo Dynasty.
It rises in a shape that curves inward from the bottom, with rounded shoulders and a narrow mouth.
The whole is made with a thick black glaze.
Since it was excavated, the skinis aged over time, but it has two rich expressions in contrast to the original glossy black glaze.

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