Problems solved by technology

[0002] Generally, Jun porcelain is composed of green body and glaze body. The green body refers to the green body of Jun porcelain that has not been pre-fired before glazing. When glazing, it will not cause cracks due to wetting the green body. The main components of the green body raw materials are ores, such as feldspar and quartz. The high silicon content makes the green body very easy to crack after cooling out of the kiln. Moreover, the embryo body of this raw material is relatively strict in the selection of raw materials. The raw materials have to go through a long-term and continuous cycle of wind, sun, rain, and freezing. The processing methods are complicated, and their quality cannot meet the manufacturing of Jun porcelain. This is also an important reason for the low yield of Jun porcelain.

preparation example Construction

[0029] A preparation method of fish maw white ice crack Jun porcelain, comprising the following steps:

[0030] (1) Weigh the ingredients according to the raw material formula of the green body, the inner layer glaze and the outer layer glaze, pulverize, mix and wet ball mill the raw materials respectively to prepare the green body slurry, the inner layer glaze slurry and the outer layer glaze slurry;

[0031] (2) Making the base slurry obtained in step (1) into a ceramic base, placing it in a kiln, and bisque firing at 860-900° C. for 4-5 hours to obtain a ceramic base;

[0032] (3) Apply the inner glaze slurry on the surface of the ceramic green body obtained in step (2), place it in a kiln, and fire it to obtain a semi-finished product under a reducing atmosphere. The firing temperature is 1200-1230 ° C, and the firing cycle is 6- 8h;

[0033] (4) Apply an outer layer of glaze slurry on the surface of the semi-finished product fired in step (3), place it in a kiln, and fir...

Abstract

A method for preparing Jun porcelain with fish maw white ice cracks. Jun porcelain with fish maw white ice cracks includes body glaze, the glaze includes inner layer glaze and outer layer glaze, and the body includes the following raw materials: potassium feldspar, montmorillonite, clay , quartz, sepiolite, diatomite, limestone, alumina, magnesia, barium carbonate; inner glaze includes the following raw materials: dolomite, porcelain stone, quartz, pearl powder, andesite powder, bentonite, zirconia, zinc oxide , alumina, cerium oxide, the shrinkage rate of the inner layer glaze is greater than that of the green body, the glaze material includes the inner layer glaze and the outer layer glaze, and the inner layer glaze is composed of dolomite, quartz, porcelain stone, andesite powder, The interaction between bentonite and auxiliary components of zirconia, zinc oxide, aluminum oxide and cerium oxide, the inner glaze has a relatively high shrinkage rate relative to the green body, and the inner glaze can produce a large The high tensile stress makes the glaze surface form many ice cracks and obtains the decorative effect of opening pieces.
