Jun porcelain bluish-white glaze

Abstract

Jun porcelain bluish-white glaze is prepared from the following raw materials in parts by weight: 55 to 60 parts of red feldspar, 13 to 15 parts of calcite, 11 to 13 parts of quartz, 1.5 to 2.5 parts of perlite, 2.5 to 3.5 parts of tourmaline, 1.8 to 2.3 parts of limestone, 1.8 to 2.2 parts of zinc oxide, and 1.4 to 1.6 parts of stannic oxide. Compared with the prior art, through scientific and reasonable raw material matching and control on the firing process, the bluish-white glaze with stable color generation can be prepared by just glazing once, the rate of finished products can reach 80% or above, and the fired bluish-white glaze is blue and lustrous in glazing color and high in jade texture feeling; in addition, the tourmaline is added into the raw materials, so that the product can release anions to surrounding to realize certain antibacterial and deodorization effects, and the product is endowed with certain biological activity, and is beneficial for health of a human body.

Description

technical field [0001] The invention relates to a glaze material, in particular to a Jun porcelain bluish-white glaze. Background technique [0002] Jun porcelain is one of the five famous kiln porcelains in the Song Dynasty in my country. The kiln is transformed into a god, and the natural transformation of the kiln is the essence of Jun porcelain art. It is a unique art treasure in Yuzhou City, Henan Province. Jun glaze is the decorative and protective layer on the surface of Jun porcelain. It is the main factor determining the glaze color of Jun porcelain. Its color and texture are closely related to the glaze formula and firing process. Qingbai glaze, commonly known as Yingqing, has a glaze color between blue and white, and its color is like jade; there are more than ten processes in traditional firing, and any problem in any process will lead to irreparable defects in the product, resulting in a low yield , less than 50%. At present, the above problems can be improved...

AI Technical Summary

Problems solved by technology

Qingbai glaze, commonly known as Yingqing, has a glaze color between blue and white, and its color is like jade; there are more than ten processes in traditional firing, and any problem in any process will lead to irreparable defects in the product, resulting in a low yield , less than 50%

At present, the above problems can be improved by adding some chemical raw materials, improving the stability of coloring and increasing the yield. However, the use of chemical raw materials is likely to cause problems that endanger human health and pollute the environment.
