Gradual change type peacock blue glaze ceramic and preparation process thereof

Abstract

The present invention relates to gradual change type peacock blue glaze ceramic and a preparation process thereof. The gradual change type peacock blue glaze ceramic comprises light-colored glaze on the surface of a ceramic blank body, and dark-colored glaze on the local part of the light-colored glaze. For the gradual change type peacock blue glaze ceramic, the surface of the light-colored glaze is thin and transparent, and has glassy luster; manganese oxide, iron hydroxide, and cobalt are introduced as color agents, so that the light-colored glaze displays slightly light blue; the dark-colored glaze is arranged in the surface of light-colored glaze, is bright, and has a strong glassy texture, the overall ceramic is blue-green; the combined degree of the light-colored glaze and the dark-colored glaze is high; the combined part is smooth, and free of cracking; and the overall color of the ceramic can be adjusted according to the thickness of the dark-colored glaze, from shallow to deep, to form a variety of lines, thus forming a unique artistic effect. The gradual change type peacock blue glaze ceramic is stable in effect, can be produced in a large quantity, increases the yield, reduces the production cost of materials, and improve the economic efficiency and market competitiveness.

Description

technical field [0001] The invention belongs to the field of ceramic products, and in particular relates to a gradient peacock blue glazed ceramic and a preparation process. Background technique [0002] Among the color glazes, peacock blue glaze is also called malachite green glaze or turquoise blue, which is a kind of medium temperature glaze with copper as the colorant.

Problems solved by technology

[0004] The above two kinds of peacock blues have their own characteristics in terms of performance effects, but in terms of production technology, they all belong to the artistic effect produced by the kiln transformation process. As we all know, the kiln transformation effect and the firing results are all random and uncontrollable. The development of a peacock blue glazed ceramic with stable effect and gradient can not only meet the aesthetic needs of consumers, but also provide a brand-new ceramic product, which has positive significance for promoting the development of ceramic products
