wujin

The term "wujin" in the context of pottery refers to a specific type of lustrous, mirror-black glaze. This glaze is achieved by adding manganese to the mixture. It was often further embellished with gilding or silvering.1

Jun kilns, active during China's Northern Song period, are renowned for their stoneware, particularly pieces with opalescent blue glazes, often splashed with purple or crimson. They also produced wares with a red, or flambé, glaze, commonly used for items like flowerpots and dishes. Guan kilns, also from the Song dynasty, are known for their stoneware with glazes ranging from pale green to lavender blue, often featuring a network of cracks emphasized with brown pigment.23
