Abstract

Jun red glaze is prepared from the following raw materials in parts by weight: 37 to 43 parts of melilite, 13 to 19 parts of quartz, 10 to 16 parts of calcite, 4.5 to 5.5 parts of sodium metasilicate, 12 to 18 parts of frit, 0.5 to 1.5 parts of bovine-derived power, 2.5 to 3.5 parts of stannic oxide, 3.5 to 4.5 parts of zinc oxide, 2 to 3 parts of talc, and 0.25 to 0.75 part of copper oxide. Compared with the prior art, through scientific and reasonable raw material matching and control on the firing process, the prepared jun red glaze is bright in color, good in glossiness, and moderate in flowability, and has fine cracks, the glazing colors are rich, on the basis of jun red, the colors including yellow, blue, purple and the like exist, the color transition is clear, distinct and natural, the rate of finished products is high, reaching 75% or above, the blank of no colorful graze exists in jun red glaze is filled, and a new variety is provided for jun red glaze.

Description

technical field [0001] The invention relates to a glaze material, in particular to a Junhong 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 "copper red glaze" in Jun porcelain is famous for its crystal clear and even moisture. Jun red glaze is a kind of copper red glaze. , the glaze cloth has fine and close cracks, bright and clean and translucent, but the glaze formula and firing process of the existing Junhong glaze fired Junhong glaze has a single glaze color and a low yield. Contents of the invention [0003] The objective of the present invention is just to provide a kind of Junhong 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 ...
