Taiwan Stamps : 1973 , TW S99 Scott1864-8 Ancient Chinese Porcelain - MNH, F-VF : In China porcelain made its debut in the period of Wei and Tsin and reached its zenith during the Sung dynasty. The porcelain industry of that time inherited the accomplishments of the Tang dynasty and Five dynasties, and developed even further. More important, manufacture skill reached new heights of excellence. Both official and private kilns developed. The most famous kilns are Ting Yao, Ju Yao, Kuan Yao, Ko Yao and Chun Yao. The most characteristic production is green porcelain known as "Celadon." Ju Yao is famous for its celadon. The celadon of Ju Yao contained elements of pale green and pink. In terms of iridescence of the glaze and fineness of quality, Ju ware surpassed all other Yao wares. In the white porcelain class, Ting Yao is the leading kiln. Not only is the core of the products quite thin, but the glaze is very white, and the decorations are exceptionally fine. Kuan Yao ware is purely bluish green. Although its glaze is inferior to that of Ju Yao, the core of the products is the best. Ko Yao ware also belonged to the celadon group. All the ware from this kiln is dull white with a crackled glaze, considered one of the finest of its time. The colour of the glaze of Chun Yao is lustrous and pleasing. The Chun Yao is well-known for furnace transmutation (Yao-Pien).In the Sung period, Chun ware sometimes underwent transmutation to red or violet after oxidation, because of copper in the green pigment. These wares are called Yao-Pien.
