    A large variety of glaze effects known by descriptive terms such as ‘hare’s fur’, ‘tortoise shell’ or ‘oil spot’, was created in the Song (AD 960–1279) and Jin (1115–1234) periods, by adding iron solutions to already iron-rich black glazes. The metallic ‘oil spot’ effect seen on this bowl, derived from an iron-rich slip under the black glaze, was particularly sought after.

    The deep, conical bowl is slightly rounded, with an incurved rim, and a low, broad, straight-cut footring with a pointed base. The rich black glaze, which ends below the rim on the outside, is decorated with small silvery specks, the rest of the outside bears a single, thin layer of brown glaze, leaving the lowest part, foot and base free. The base has grit adhering.
