Jun porcelain bluish white glaze and preparation method thereof

Abstract

The invention discloses Jun porcelain bluish white glaze and a preparation method thereof. The Jun porcelain bluish white glaze is prepared from the following raw materials in parts by weight: 43 parts to 48 parts of melilite, 13 parts to 19 parts of calcite, 15 parts to 21 parts of quartz, 2 parts to 3 parts of tin oxide, 2.5 parts to 3.5 parts of fired talc, 0.9 part to 1.1 parts of zirconium silicate, 1.5 parts to 2.5 parts of zinc oxide, and 1.5 parts to 2.5 parts of tourmaline. The preparation method of the Jun porcelain bluish white glaze comprises the following steps: (1) adding water into the raw materials and mixing; carrying out ball milling to obtain glaze slurry; (2) glazing; (3) firing at firing temperature of 1280 to 1300 DEG C. The Jun porcelain bluish white glaze and the preparation method of the Jun porcelain bluish white glaze disclosed by the invention have the beneficial effects that by adding chemical raw materials including tin oxide, zinc oxide and zirconium silicate into a conventional raw material, so that the finished product rate is increased from originally being less than 50 percent to 80 percent or above; by adding the tourmaline, the product can slowly release negative ions to surrounding environment, so that certain antibacterial and deodorizing effects are achieved.

Description

technical field [0001] The invention relates to a glaze material, in particular to a Jun porcelain moon white glaze. Background technique [0002] Jun Porcelain is one of the five famous kiln porcelains in Song Dynasty in my country. The reputation of "one piece of Jun porcelain" is a unique national treasure porcelain in Shenhou Town, Yuzhou City. The "moon white glaze" in the color glaze of Jun kiln is lighter than the sky blue glaze. It is as white and clear as moonlight, and the enamel is smooth and moist. The formation of glaze color has a lot to do with the raw material formula and firing process. Because the traditional firing of Jun porcelain moon white glaze uses natural ore as the main raw material, various problems are prone to occur during firing, such as shrinkage of the glaze surface and pinholes, etc., resulting in a yield of less than 50%. However, by adding some chemical raw materials The above-mentioned problems can be improved and the yield rate can be in...

Problems solved by technology

Because the traditional firing of Jun porcelain moon white glaze uses natural ore as the main raw material, various problems are prone to occur during firing, such as shrinkage of the glaze surface and pinholes, etc., resulting in a yield of less than 50%. However, by adding some chemical raw materials It can improve the above problems and increase the rate of finished products. However, the use of chemical raw materials has caused new problems, such as endangering human health and polluting the environment.
