An early white porcelain bowl fired in the Sui dynasty. It has a relatively large body, a sharp silhouette and a flat base that are common to this type. The same kind was excavated from the Xing and Jingxian kiln sites in Hebei province.

The prototype of white porcelain, which developed significantly during the Sui dynasty, can be broadly divided into those coated with white slip and those coated with a transparent glaze directly. This piece is the first example with white slip, but it is a rare piece with a wide exposed lower body. The contrast of white and grey, reminiscent of Muji-Hakeme (plain brushmark slip) of Buncheong ware, and the ridged rim create tea pottery taste reminiscent of Korai Chawan (Korean teabowls).

There are earthen stains, but not much ageing and the surface is beautifully lustrous—good condition with no noticeable flaws other than kiln scratches. The brown parts on the base must be iron. It comes with a box.
