This unique white porcelain vase from the 18th century actually consists of two parts: the decorative openwork’s outer surface conceals a cylindrical inner jar. There is a vine design painted in a ring around the neck, and an embossed relief near the foot, with the motif of a ceremonial scepter (yeouidumun, 如意豆文). In between, the entire outer body is filled with the openwork peony design. A light blue glaze is thinly applied, and the glazed surface is clean and clear. Joseon ceramics are typically known for their simplicity and austerity, but this jar is a rare example featuring complex openwork decoration. Given the superior quality and the glaze color, this piece was likely made especially for the Joseon royal court.
