Consisting of a cover and body, this relic is assumed to have been produced as royal white porcelain around the area of Gwangju, Gyeonggi Province, in the early Joseon period, judging from its form, color, the shape of its foot and the prop. This is pure white porcelain without any particular decoration, while the flat brim curls outward and the shoulder falls in a large oval shape before narrowing in oblique lines.
