Abstract

Jade glaze of jun procelain is prepared from raw materials in parts by weight as follows: 37-43 parts of yellow feldspar, 27-33 parts of quartz, 13-19 parts of calcite, 3.5-4.5 parts of sodium silicate, 4.5-5.5 parts of knar clay, 1 part of cattle bone powder, 3.5-4.5 parts of stannic oxide and 0.5-1.5 parts of zinc oxide. Compared with the prior art, the jade glaze has the advantages that through scientific and reasonable raw material matching and firing process control, the defects of poorer color and poorer jade texture in traditional firing of the jade glaze of the jun porcelain are overcome, the yield of finished products is increased to 90% or above, and environmental pollution caused by raw materials is reduced in production.

Description

technical field [0001] The invention relates to a glaze material, in particular to a Jun porcelain jade glaze. Background technique [0002] Jun Porcelain is one of the five famous kiln porcelains of the Song Dynasty in my country. It is a treasure in the traditional Chinese porcelain making process. It is famous all over the world for its unique kiln transformation art. The "Jade Glaze" in Jun Porcelain is known as the "Pearl of Jun Kiln" because of its color like blue waves, ice like jade, elegant and solemn, and it is traditionally fired with local ores such as feldspar, quartz, and calcite in Yuzhou. Raw materials, poor color, weak jade texture, low yield, only about 40%. Contents of the invention [0003] The object of the present invention is to provide a kind of Jun porcelain jade glaze for solving the deficiencies in the prior art. [0004] The purpose of the present invention is achieved with the following technical solutions: [0005] A Jun porcelain jade glaz...
