AI Technical Summary

Problems solved by technology

Therefore, bone china is a medium-temperature ceramic with weak density.
Therefore, when bone china meets blue and white pigments, because the density of bone china products is low, and the pigments containing cobalt and chromium have high permeability, the result often causes the blue and white pigments on the fired bone china to penetrate into the bone. In the porcelain body of high-quality porcelain, the edges of the blue and white patterns tend to spread, resulting in blurred patterns and colored flowers, and it is difficult to achieve the general effect of blue and white porcelain, thus limiting the application of high-permeability pigments in bone china products

Abstract

The invention relates to shaping glaze and a firing technology of bone china containing a high-permeability pigment. The shaping glaze consists of the high-permeability pigment and ingredients comprising components in percentage by weight as follows: 30% to 45% of potash feldspar, 5% to 12% of kaolinite, 20% to 40% of quartz, 2% to 6% of fired talc and 10% to 20% of lead-and-cadmium free fritted glaze. According to the firing technology, the shaping glaze is introduced, and three firing technologies of color baking, shaping glaze coating and surface layer glaze coating are used. According to the shaping glaze and the firing technology of the bone china containing the high-permeability pigment, the shaping glaze is introduced, and three firing technologies are used, so that conventional two times of high-temperature firing are broken through, the pigment containing cobalt and chromium is in the charge of the shaping glaze, the pigment is prevented from spreading and permeating, the problem that high-permeability pigments cannot be applied to a bone china product is fundamentally solved, and the color system of the bone china product is enriched.

Description

technical field [0001] The invention belongs to the field of ceramic materials, in particular to a component of a shaping glaze for bone china and a firing process of a bone china embryo containing high permeability pigments using the shaping glaze. [0002] Background technique [0003] Nowadays, among household porcelains, bone china products are favored by people because of their thin and translucent characteristics, but the colors are less than those of traditional Chinese ceramics. Especially the unique Chinese porcelain with blue and white patterns is very popular in the world. If the traditional blue and white patterns are applied to Bone china will have a huge impact. However, the traditional Chinese blue and white pattern is made of cobalt-containing and chromium-containing high-penetration pigments and other compositions in a certain proportion and then painted on the white porcelain embryo. Due to the traditional Chinese ceramic firing process and bone china Dep...
