Longquan Celadon (Qingci)

龙泉青瓷 (Lóngquán Qīngcí)

Longquan celadon is a jade-green glazed stoneware tradition from Longquan city, Zhejiang province — inscribed on UNESCO's Representative List in 2009 and considered one of the supreme achievements in world ceramics. The technique depends on a multi-layer glaze application of feldspar-limestone slip fired in reducing kilns at 1,260–1,310°C, producing the characteristic plum-green (méi zǐ qīng) or pale blue-green (fěn qīng) surface. The two classical lineages — Ge ware (crackled glaze) and Di ware (smooth glaze) — require different clay bodies and glaze chemistry. The procedural knowledge of matching clay shrinkage rates to glaze expansion, controlling kiln atmosphere by reading flame color and smoke opacity, and executing the multi-dip glaze layering sequence is transmitted through master-apprentice lineage and is not reducible to industrial specification.
