Problems solved by technology

The picture of finished bone china is not wear-resistant, and the color is not saturated. The biggest disadvantage is that lead and cadmium are dissolved, which cannot meet the standard of daily-use porcelain.
[0003] Although the existing relatively advanced underglaze color process can solve the problems of wear resistance and lead and cadmium dissolution of the picture, but due to the poor ability of the embryo body to adhere to the pigment, there are still difficulties in painting, and it is impossible to repeatedly color at the same position, and the color of the finished product is not saturated. Disadvantages of rough picture
Moreover, due to the constraints of the production process, it is easy to cause decolorization (color fade) after high-temperature biscuit firing

Abstract

The invention relates to a process for producing in-glaze color bone china. The surface of a green blank is applied with a layer of mixed glaze material in the general process, the green blank of which the surface is applied with the mixed glaze material is biscuited at a temperature of between 650 and 800 DEG C, then a pattern is drawn on the surface of a biscuit through high-temperature packagepigments, and then the processes such as high-temperature biscuiting and the like are carried out to generate the surface of the biscuit providing more convenience for drawing. The blank body has strong tinting strength and smudging force to achieve the effect of Chinese painting canvas, and tinting and chapped dyeing can be repeatedly carried out on the same position. Bone china finished products produced and processed by the process have the advantages of brilliant and full color, moist pictures, bright glaze surface and light and thin blank body.

Description

technical field [0001] The invention relates to a production process of bone china, in particular to a production process of in-glaze color bone china. Background technique [0002] Ordinary bone china is mainly decorated with overglaze color and pasting flowers. The picture of finished bone china is not wear-resistant, and the color is not saturated. The biggest disadvantage is that lead and cadmium dissolve, which cannot meet the standard of daily-use porcelain. [0003] Although the existing relatively advanced underglaze color technology can solve the problems of wear resistance and lead and cadmium dissolution of the picture, but due to the poor ability of the embryo body to adhere to the pigment, there are still difficulties in painting, and it is impossible to repeatedly color at the same position, and the color of the finished product is not saturated. The disadvantage of rough picture. Moreover, due to the restriction of the production process, it is easy to cause...
