Stoneware vessels with pale greenish glaze and stamped scrolling patterns were made in the Warring States period. Many of the vessel shapes can be seen to imitate those of bronzes. The stamped spiral patterns decorating these stonewares also derive from bronze ornament

A jar of similar shape and with similar supports and handles, but encircled by a grooved band, is illustrated by Mitsuru Uragami, Ancient Chinese Ceramics from the Neolithic Period to the Western Han, vol. I, Tokyo, 1991, p. 55 (bottom)
