As with the majority of square vases, the body has been molded together, the neck then wheel thrown and luted onto the shoulder. The low, wide square foot-ring is beveled and has a glazed square recess at the center. A fabric impression remains on the otherwise unglazed foot. The ceramic body is white, except where it has burned orange at the foot-ring. There is one vertical hairline crack in the neck. A crack in the foot has been repaired.
