Manufacturing method of decorative porcelain

Abstract

The invention provides a manufacturing method of decorative porcelain. The method comprises the following steps: (1) preparing at least two kinds of colored clay with different colors; sequentially or randomly laminating the at least two kinds of colored clay with different colors to a preset height; (3) cutting the laminated colored clay, putting the colored clay into a mold, rolling, drying or airing, and demolding; (4) putting the demolded clay body into a fine trimming machine, and carrying out fine trimming; (5) drying or airing the clay body subjected to fine trimming, applying transparent glaze, and airing; (6) putting the glazed clay body into a kiln, and firing; and (7) after finishing firing, shutting down the kiln, and cooling to obtain the decorative porcelain. According to the method, the body stain is directly added into the raw material porcelain clay to prepare different kinds of colored clay with different colors, and the at least two types of colored clay are laminated together to manufacture the porcelain with various patterns.

Description

technical field [0001] The invention relates to the field of porcelain production, in particular to a method for producing colorful porcelain. Background technique [0002] Ceramics is the general term for pottery and porcelain. The Chinese invented pottery as early as about 8000-2000 BC (Neolithic Age). Ceramic materials are mostly oxides, nitrides, borides and carbides. Common ceramic materials are clay, alumina, kaolin and so on. Ceramic materials generally have higher hardness, but poor plasticity. In addition to the use of tableware and decoration, it also plays an important role in the development of science and technology. The raw material of ceramics is obtained by quenching the earth's original large resource clay. The nature of clay is tough, it can be molded when exposed to water at room temperature, it can be carved when it is slightly dry, and it can be ground when it is completely dry; it can be made into pottery and can hold water when it is fired to 700 ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the different colors formed on the inner and outer walls of the porcelain are applied to the porcelain by spraying, brushing or immersing the colors, and after being calcined, they become colored glazed porcelain, but the process of spraying, brushing or immersing is due to the It is easy to flow and needs to be stacked several times to accumulate a certain thickness of coating. The operation process is time-consuming and labor-intensive, and it is impossible to shape the required three-dimensional shape on the surface layer again.

During the calcination process of porcelain, the coating will still flow after the glaze layer is vitrified, so it is difficult to form a large area of ​​thick and uniform color coating on the surface of the porcelain, especially for porcelain made by high-temperature calcination, the surface color of the fired porcelain is more difficult to be uniform , greatly increasing the difficulty and workload of the manufacturing process
