Problems solved by technology

However, the existing glaze formula for firing Lu Jun glaze is easy to lose and cannot be controlled during the firing process. Traditional firing is done in a small kiln, and one kiln can only fire one piece of larger blank or two pieces. -3 pieces of smaller green tires, and the success rate of this firing method is extremely low, and it is still at the stage of "ten kilns and nine failures"

Abstract

Lujun glaze is prepared from the following raw materials in parts by weight: 37 to 43 parts of original medicine, 7 to 13 parts of melilite, 12 to 18 parts of plant ash, 6 to 10 parts of glass, 7 to 13 parts of quartz, 2.5 to 3.5 parts of stannic oxide, 4.5 to 5.5 parts of zinc oxide, 2.5 to 3.5 parts of copper oxide, 3.5 to 4.5 parts of blue powder and 2.5 to 3.5 parts of talc. Compared with the prior art, the Lujun glaze has the advantages that the glaze is not liable to loss and can be controlled through scientific and reasonable raw material proportion and a control firing process; meanwhile, big kiln firing can be realized; the fired Lujun glaze has rich glaze colors and little floating light, the glaze surface is natural and not dull, gold spots occur on the surface, and the rate of the finished products can reach 60 percent or higher.

Description

technical field [0001] The invention relates to a glaze material, in particular to a Lujun 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 "Lu Jun Glaze" in Jun porcelain is colorful, jade-run and crystal-clear, the glaze surface is natural but not rigid, mixed but not chaotic, coupled with unpredictable markings, its natural effect is far beyond that of other Jun porcelains. Therefore, it has become a bright pearl in the garden of Juncibai. However, the existing glaze formula for firing Lu Jun glaze is easy to lose and cannot be controlled during the firing process. Traditional firing is done in small kilns, and one kiln can only fire one piece of larger green body or two. -3 pieces of smaller blanks, and the success rate of this firing method is ext...
