A large blue-glazed Junware bowl. The glaze falls short of the foot rim leaving the foot and base unglazed and revealing the dense, grey stoneware.
Jun ware, the last of the `five famous wares of the Song dynasty', differs from the others in style. Its heavy potting and thick glaze were best suited to fairly simple shapes. The attraction of the glaze is immediate and depends on its bright colours. Vessel shapes are simple and the range is small. Most common are well-rounded bowls in all sizes. Heavy potting is characteristic and the stoneware body can be yellowish, buff or grey. The glaze is thick and opaque, and tends to be very bright except at the rim, where it fades to a mushroom colour. From the twelfth century onwards and particularly during the Jin dynasty, the strong visual impact was intensified further when the blue glaze was combined with contrasting splashes of a deep purplish-red derived from copper.
