A white porcelain teabowl from the Goryeo dynasty. A neat morning glory-shaped body is covered entirely with a pale bluish glaze, leaving sand marks on the base. Goryeo white porcelain kiln sites have been discovered in Gochang-gun and Yongin-gun, and the production period is estimated to be from the late 10th century to the early 11th century. The neat body with a ring-shaped base called ‘Haemurigup’ is reminiscent of the Xing ware white porcelain bowls exported worldwide (excavated from Iksan City, Jeollabuk-do), as well as Yue ware celadon.

The body is naturally distorted, and the marks on the foot cause rattling. But there are no noticeable flaws other than a slight ageing in the well.
