Glossary
celadon
A ceramic glaze containing iron. It must be fired by the reduction method, with its red iron oxide (ferric) reduced to black (ferroso-ferric). The final color of the glaze is either olive green, gray-green, or gray. Celadon ware was developed and perfected during the prosperous Sung [or Song] dynasty (960-1279). It was valued by the Chinese largely because of its resemblance to jade. The pigment known as celadon green is also called green earth, the main ingredient of which is celadonite, an iron silicate. Chinese and Korean celadon porcelain was named for the resemblance of its color to this pigment. The word originated as the name of a character in the 1610 story by Frenchman Honoré d'Urfé, L'Astrée.
