Song vase in hexagon shape with two handles in under double crackle glaze. There is a small crack at the top edge. Height: 22.3cm.Craquelure affecting deliberate glazing effects are usually known as "crackle", with crackle glaze or "crackle porcelain" being common terms. It is typically distinguished from crazing, which is accidental craquelure arising as a glaze defect, although in some cases, experts have difficulty in deciding whether milder effects are deliberate or not. Some may also only have developed with age. Leading Chinese wares of the Song and Yuan dynasties with deliberate crackle glazes are Guan ware and Ge ware; in Ru ware, the milder crackle may be accidental, though the majority of pieces have it. The crackle may take some time to appear after firing and is probably mainly caused by rapid cooling and perhaps low silica in the glaze.
