Celadon glazing
Celadon glazing is a ceramic glazing technique that produces translucent green or blue-green surfaces, traditionally achieved through iron-based glazes fired in a reduction atmosphere. The glaze is historically associated with East Asian ceramics and has influenced pottery traditions in China, Korea, and Japan.
Celadon glazes typically contain small amounts of iron oxide. When fired at high temperatures in a reduction atmosphere, the iron produces characteristic green tones ranging from pale gray-green to deep jade-like colors. The resulting glaze surface is often smooth and translucent, sometimes revealing the texture or carving of the clay body beneath.
The technique developed in China during the early centuries of ceramic production and reached a high level of refinement in the celadon wares of the Song dynasty. Celadon ceramics later influenced pottery traditions throughout East Asia.
In Japan, celadon-type glazes are often referred to as seiji and appear in several ceramic traditions, particularly in porcelain production. The glaze is valued for its quiet color tones and refined surface quality.
Celadon glazing may also highlight carved or incised decoration beneath the glaze, as the translucent surface allows subtle patterns to remain visible after firing.
