Celadon Porcelain, Ceramics and Stoneware
Celadon is essentially a term coined by the Europeans to describe a wide range of porcellanous wares from both China and Korea which have a distinctive pale grey-green or blue-green glaze. To the Chinese it is known as 'Qingci' which simply translates as greenish porcelain.
Components of celadon glazes
The basic components of celadon glazes are feldspar, lime, potash, silica and iron which form an alkaline compound necessary for the production of green from iron oxide. By varying the ratios of these components different kinds of fluidity and viscosity can be achieved.
There are many subtle shades, tones and textures of celadon wares. However, to an inexperienced eye there would appear not to be much contrast. There is a certain opacity in celadon wares which is not indifferent to some jades. Taking into account that the Chinese view jade as being possibly the most precious of all materials, it can be concluded that the primary objective of creating celadon wares was to emulate jade.
