The pale blue glaze is evenly distributed over the vessel except where it has pooled, creating darker bands. These areas are at the base of the knob and just above the foot. The interiors of the lid and bowl are much paler. There is one particularly noticeable pinhole in the glaze on the lid exterior, and there are some smaller interior pinholes and black spots. The unglazed paste of the foot-ring and interior flanges is very smooth. A rusty orange residue appears on the unglazed flanges of the lid and bowl, and is slightly visible from the exterior when the lid is on. Although the cover shifts slightly when the vessel is moved, the flanged construction of the bowl ensures stability.
