Bowl with rim

The terms yin and gui in modern Chinese archaeology both refer to bowls with a footring of this shape. Footrings were an innovation of Neolithic potters that made flat-based bowls easier to pick up, and the addition of footrings to bowls increased rapidly in ceramic and bronze production during the Shang-Zhou era. A large number of such bowls appear in the Shang dynasty's central region, Henan, and its surrounding vicinities: Hebei, Shaanxi, and Shanxi. The neatly treated wide rim of this tapered vessel, along with its decorative motifs of chevrons and cord marks, clearly illustrate the Henan tradition.
