Porcelain from the Southern Song official kilns predominantly features a pale greenish-blue glaze (fenqing), with a smaller number in grayish-green. Their forms carry on the refined elegance and ritual propriety consistent throughout the Song Dynasty (960-1279), focusing mainly on simple, archaic and dignified display wares. Daily-use vessels and ritual objects are equally tasteful, embodying the unique literati aesthetic of ancient Song charm. The glaze is generally thick, and the glaze surfaces are often marked with crackles.
