A small white porcelain bowl, fired during the Goryeo dynasty. The wall flares widely from a small foot, opening into a form reminiscent of a morning-glory flower. A single incised line encircles the well. The vessel is glazed throughout, including the interior of the foot, while firing supports have left marks on the footring. The milky-white glaze takes on a faintly warm tone where exposed to the heat of the kiln, and fine crackle covers the surface. Only the pool of glaze at the centre of the well settles into a pale green.

White porcelain began to be produced in Goryeo alongside celadon around the tenth century, although celadon remained the dominant ware. While examples have been excavated at sites such as the Seori kiln in Yongin, surviving Goryeo white porcelains are exceptionally rare. This small bowl recalls the form of Chinese Tenmoku wares and evokes a period in which the practice of drinking tea had become established in Goryeo society. Its palm-sized proportions also make it well suited to use as a sake cup, offering a rare opportunity to bring the quiet beauty of Goryeo white porcelain into everyday use.

One relatively long hairline extends from the rim, accompanied by a second, very short hairline. Apart from these and kiln imperfections, there are no notable defects, and the overall condition is good. Accompanied by a fitted wooden storage box.
