Problems solved by technology

The traditional kiln-changing glaze is fired at medium and high temperature, the firing temperature is above 1200°C, and the firing time is mostly more than 12 hours. The high firing temperature, long time, and large energy loss lead to high cost and are not environmentally friendly; There are light-weight Baiyun pottery kiln-changing glazes with a single glaze effect and monotonous varieties, which cannot meet the needs of consumers with different personalities

Abstract

The invention belongs to the field of ceramic manufacturing, and in particular relates to a kiln-transformed glaze formula, preparation method and application method for firing light-weight porcelain. The formula of the low-temperature kiln-changing erythema glaze for light-weight porcelain includes glass powder, transparent frit glaze, red material, nepheline powder, boric acid, kaolin, and zinc oxide. The kiln-changing erythema glaze formula glaze has low cost, is convenient to use, has a low firing temperature and has a unique artistic sense. The glaze effect produced by this kind of kiln-change erythema glaze has a red or copper-red background color, and irregular black spots are evenly distributed on the background color. The size and density of the black spots depend on the type of ceramic and the glaze The thickness varies, with a unique artistic effect. Porcelain made with this kind of glaze improves the product grade and sales price, and has high economic value; in addition, this kind of glaze can be mass-produced industrially, can be popularized quickly, is easy to use, and has strong competitiveness in the market.

Description

technical field [0001] The invention belongs to the field of ceramic manufacturing, and in particular relates to a kiln-transformed glaze for firing light porcelain, a preparation method and a use method. Background technique [0002] Kiln-changing glaze means that when the utensils are fired in the kiln, due to the oxidation or reduction of various color elements in the kiln, they will show unexpected glaze color effects after they come out of the kiln. The traditional kiln-changing glaze is fired at medium and high temperature, the firing temperature is above 1200°C, and the firing time is mostly more than 12 hours. The high firing temperature, long time, and large energy consumption lead to high cost and are not environmentally friendly; There are light-weight Baiyun pottery kiln-changing glazes with a single glaze effect and monotonous varieties, which cannot cater to the needs of consumers with different personalities. [0003] In order to solve the above problems, the...
