The pale blue glaze ends just above the unglazed foot, which is unusually narrow. A small patch of dull glaze occurs midway down the vessel. A few dark spots appear on the thickened mouth rim, one side of which is slightly rough; some pinholes in the glaze are visible on the vessel's upper shoulder. On the shallow concave base the clear glaze over the reignmark is marred by a dark line, a firing flaw, intersecting the kang character. Small amounts of dirt and kiln debris adhere to the interior.
