History of green glaze

In China, copper was used as colorant to burn lead blue glaze in Han Dynasty, and the blue glaze on porcelain in Song Dynasty was more common. However, before the burning of malachite green in Ming Dynasty, all green glazes were dark turquoise, which did not reach the level of bright green. Therefore, successful green glazes are the products of Ming and Qing dynasties. Such as Langyao Green and Apple Green in high-temperature green glaze, Peacock Green, Guapi Green and Okra Green in low-temperature green glaze.

Peacock Green Peacock Green is also called "Fatui", also called jade glaze or auspicious glaze. There are two shades of glaze color; Deep color is lush, with fine particles in the glaze, lined with white glaze bottom, and the glaze color is bright and gorgeous; The former is mainly used for colored glazes, such as eggplant skin purple and other glazes, often accompanied by malachite green. If malachite green is painted on blue and white, the color of blue and white will turn black, which is quite similar to malachite green and black flowers in Cizhou kiln in Song Dynasty.

Malachite green is a low-temperature glaze with copper as colorant. The firing of folk kilns in Song and Yuan Dynasties was first seen in Cizhou Kiln in Song Dynasty. During Chenghua period of Ming Dynasty, Jingdezhen began to fire a single peacock green glaze on porcelain. There are two kinds of firing methods: first, the glaze is directly fired with plain tires, and the glaze is easy to peel off; One is to burn the glaze on a white glaze device, and few people peel the glaze.

Turquoise green turquoise green, also known as okra green, is a new variety of green glaze created and fired during Yongzheng period of Qing Dynasty. Modern formula is made of barium sulfate, calcium carbonate and boric acid. Its color is light yellow, slightly green, similar to turquoise, hence the name "turquoise green".
