A Katate-type teabowl fired in the early Joseon Dynasty. It has a neat opened shape with a bamboo joint base. Spur marks are left on the well, and a circle dent in the well called Kagamiochi (mirror drop) is designed. This piece is an example of using relatively soft clay in the Katade-type and the brown clay commonly used in Buncheong ware. And the whiteness of the glaze creates coarse white porcelain quality.

Contrary to its profound inherited taste, it is almost intact, suggesting it was used with great care. It fits in a box labelled “Korai Chawan”.
