Black gold sand glaze porcelain, and preparation method thereof

Abstract

The invention belongs to the field of ceramic glaze material, and more specifically relates to a black gold sand glaze porcelain widely applied to the fields of art ceramic or household ceramic, and a preparation method thereof. According to the preparation method, black gold sand effects of the black gold sand glaze porcelain are realized via combination of bottom glaze and surface glaze, the black gold sand glaze porcelain obtained via firing possesses black bottom color, and the black bottom color is covered with golden gold sand particles; under a microscope, the gold sand particles are polygonal particles, light-reflecting effect of the gold sand particles is excellent, striking contrast effect and unique artistic effect are achieved via combination of the black bottom color with the gold sand particles; the bottom glaze and the surface glaze of the black gold sand glaze porcelain are combined firmly; and service life is long. The invention also provides the preparation method of the black gold sand glaze porcelain; the glaze surface effect can be achieved via adjusting the formula and thickness of bottom glaze with surface glaze; black gold sand glaze porcelain finished product ratio is high; firing temperature is low; energy is saved; the preparation method is friendly to the environment; and energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of ceramic glazes, and in particular relates to a black gold sand glazed porcelain widely applicable to art ceramics or household ceramics and a manufacturing process thereof. Background technique [0002] With the continuous improvement of people's living standards, people's living standards are getting higher and higher, and consumers have higher and higher aesthetic requirements for ceramic products. However, the key material that plays a decorative effect on ceramic products is glaze. [0003] Jinsha glazed porcelain is made of numerous tiny metal iron oxide crystals obtained under the control of high temperature and firing with a high amount of iron. These crystals are not formed on the surface of the glaze, but suspended in the glaze layer. When light shines, they can reflect The light is very similar to the placer gold in nature, so it is called "golden sand glaze". The existing golden sand glaze is to introdu...

AI Technical Summary

Problems solved by technology

[0004] There are the following problems in the effect and preparation of the existing Jinsha glazed porcelain. In effect, the background color of the existing Jinsha glaze is mostly gray or brown, and the gold sand is mostly yellow or brown. And the artistry is not strong, and because the gold sand particles are suspended in the glaze layer, its reflective effect is also affected; in terms of preparation, the gold sand in the glaze of the existing gold sand glaze is randomly generated during firing, so the glaze of the gold sand layer The surface effect is random, it is not easy to control, and the firing rate and good product rate are low. In addition, in order to fire Jinsha, the firing temperature of the existing Jinsha glaze must be above 1280, which has high firing temperature and high energy consumption. Therefore, The existing golden sand glaze needs to be further improved both in terms of effect and production process
