Low-temperature kiln-transformed zirconium white glaze without bottom glaze, its preparation and application method

Abstract

The invention belongs to the field of ceramic production and particularly relates to a ground-glaze-free low-temperature transmutation zirconium white glaze formula, a preparation method and a use method thereof. The ground-glaze-free low-temperature transmutation zirconium white glaze formula includes feldspar powder, boric acid, barium borate, limestone, zinc oxide, lead oxide, lead silicate and bentonite. The glaze is low in cost, is convenient to use, is low in sintering temperature and has a unique artistic feel. Glaze surface produced by sintering the ground-glaze-free low-temperature transmutation zirconium white glaze has a zirconium white dark light bottom color, wherein irregular black spots are uniformly distributed on the glaze surface. The size and distribution density of the black spots are changed according to the model of a ceramic product and glaze thickness. The glaze surface has a stone-like appearance and a slight flowing-tendency effect, thereby achieving unique artistic effects. Porcelain produced with the glaze is increased in grade and market price and is high in economic value. The glaze can be produced in large scale, can be popularized quickly and is simple in use, thereby achieving strong market competitiveness.

Description

Technical field [0001] The invention belongs to the field of ceramic manufacturing, and specifically relates to a low-temperature kiln-changing zirconium white glaze material without glaze, preparation and use methods. Background technique [0002] When the kiln becomes glaze, when the utensils are fired in the kiln, because the kiln contains a variety of color elements, after oxidation or reduction, it will show an unexpected glaze color effect after leaving the kiln. The traditional kiln changes the glaze to medium-high temperature firing, the firing temperature is above 1200℃, and the firing time is mostly above 12 hours. The firing temperature is high, the time is long, and the energy consumption is large, resulting in high cost and environmental protection; The glaze effect of the light-weight dolomite kiln glaze is single and the variety is monotonous, which cannot meet the needs of consumers with different personalities. [0003] In order to solve the above problems, the in...

AI Technical Summary

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
