Goryeo Small Tea Bowl with Knead Design

A small bowl made in Goryeo.
The knead technique began in China during the Tang Dynasty and continues through the Qing dynasty.
In China, two different types of soil were mixed together to create a marbled pattern.
On the other hand, the knead technique of the Goryeo Dynasty used three types of celadon decoration: celadon clay, white clay, and red clay.
This item has distinct white, gray, and black colors, and a nearly transparent celadon glaze is applied to create a beautiful marble-like pattern.
Since celadon knead mixes different types of clay, it is prone to cracking during firing due to differences in shrinkage rates, making examples extremely rare.

There is no conspicuous flaws.There are some aged deterioration on the whole surface, but there is luster.
