Goryeo Dynasty Celadon Cylindrical Cup with Carved Lotus Design

A cylinder-shaped celadon tea bowl made in the Goryeo Dynasty.
It is a very small tea bowl that can hold about a mouthful of water.
It stretches straight in the vertical direction with a thickness of about 3 mm.
The bottom is also very small to match the vessel, but it is a perfect circle and very polite.
The body is engraved with intaglio patterns, with a thunder pattern on the top, a lotus flower pattern in the center, and a lotus petal pattern on the bottom.
The intaglio lines are very thin, and the strength and weakness are added to the lines.
The lotus flower is so polite that it can be seen three-dimensionally.
At a time when icarved is an easy-to-understand ornate decoration technique, carved is applied so that you cannot tell at first glance that there is a pattern.
The casual decoration that seems to melt into the grey-blue celadon glaze was popular among the aristocrats due to its high quality.
t is a design that fits into everyday life, and I imagine that it was used by nobles to take medicine.

There is some scraping of the glaze on the rim, but it is thought to be a scratch during firing.There is one tiny chip on the bottom.
There is one long crackle-glazed in the vertical direction, but it does not reach the vessel.
