Abstract

The invention relates to a method for manufacturing medium-temperature Longquan powder celadon. In the method, a green body and a glaze are mixed with common mineral materials and chemical materials in specific ratios, calcined zinc oxide and calcined talcum are added in the glaze, the Longquan powder celadon is fired at 1,220 to 1,240 DEG C at one time, the problems of high production cost, serious environmental pollution and the like, which are caused by high firing temperature and large energy consumption, of the conventional powder celadon production are solved, the jade textural quality of medium-temperature powder greenish glaze is strengthened.

Description

technical field [0001] The invention belongs to the technical field of traditional ceramic manufacturing, and in particular relates to a method for manufacturing medium-temperature Longquan powder celadon, which is suitable for manufacturing various high-grade Longquan powder green porcelain for daily use and art porcelain. Background technique [0002] Longquan powder celadon is one of the famous celadon varieties created and fired in the heyday of the ancient Longquan kiln. It uses iron as the main coloring element, and the glaze is thicker. After entering the kiln, it is fired with a reducing flame. Jade-like texture. Longquan kiln celadon went from strong to weak, and after thousands of years, it declined in the late Qing Dynasty. After liberation, under the care of Premier Zhou Enlai, production was resumed in Shangyang Town, Longquan City. Now it has formed a certain scale and has become one of the largest celadon manufacturing places in China. Although Longquan cela...
