Like 1942.9.499, there is considerable variation in the intensity of the pale green glaze. There is a pinhole in the glaze in the exterior of the neck and a tiny extrusion at the bottom of one petal. The glaze does not end in as neat a line above the foot-ring as in 1942.9.499, and the foot-ring is slightly rougher. The foot is very shallow, and the reignmark is a strong blue under the colorless glaze on the base.
