This shard is from a heavily potted rim section of a Jun ware. It is bluish in colour with a pitted surface. The famous Jun kiln of the Song (960-1279) and Jin (1115-1234) dynasties was located in present-day Yu county in Henan province, China. The kiln made use of iron and copper colourants to fire different hues of a bluish glaze. Jun ware is esteemed as one of ‘the five great wares of China’ by connoisseurs in the Southern Song, Ming and Qing dynasties.
