Problems solved by technology

Black glaze is a bright or matte black glaze. Because the colorant in the black glaze has a strong coverage of other colors, the general black glaze appears as a solid color. In order to add other expressive effects on the basis of black , the black glaze represented by Tianmu glaze is widely used, and its characteristic is that it can present spots of different colors on the black surface. However, Tianmu glaze has high requirements on the firing environment, and the effect of the spots on the control of temperature is extremely high. , so the yield is low, and the light shift effect can also be achieved by adding fluorescent powder to the glaze, but the shape in the daytime is not obvious, and the shape surface is relatively simple. In view of this, this case arises

Abstract

The invention relates to the field of ceramic products and preparation methods thereof, in particular to a black matte glaze ceramic and a preparation method thereof. According to the invention, nanoscale agate powder is added into a cover glaze, so that the roughness of the surface of the cover glaze can be reduced, and the cover glaze shows a black matte ground color; ground glazes on the inner surface and the outer surface of a green body are transparent glazes containing fluorescent powder, a light source is introduced into the green body through an opening in the daytime, light is absorbed, and the fluorescent dot effect observed through the black matte cover glaze and the hollow part of the green body in the daytime is contrasted with the black ground glaze; the ground glaze in the green body absorbs light in the daytime, the large-area ground glaze containing the fluorescent powder plays a role in brightening the hollow-out inner glaze in the dark night, the middle-layer gray glaze forms firewood-fired flames and gray glaze lines, and at night, the fluorescent light decorated in the streamer gray glaze can be observed through the black matte cover glaze and the hollow-out part of the green body, the fluorescent light looks like flow cloud and starlight at night, and unique ornamental value is achieved.

Description

technical field [0001] The invention relates to the field of ceramic products and a preparation method thereof, in particular to black matte glaze ceramics and a preparation method thereof. Background technique [0002] Glaze is an extremely thin layer of material applied to the surface of the ceramic body. It is based on the performance requirements of the body, using natural mineral raw materials and chemical raw materials to be configured in proportion, and melted under the action of high temperature to cover the surface of the body. Glossy vitreous layer. The purpose of glazing is to improve the surface performance of the green body, improve the usability of the product and increase the aesthetic feeling of the product. Black glaze is a bright or matte black glaze. Because the colorant in the black glaze has a strong coverage of other colors, the general black glaze appears as a solid color. In order to add other expressive effects on the basis of black , the black gla...
