Blue-and-white pigment used in bone china and fabricating technology for blue-and-white bone china

Abstract

The invention relates to a blue-and-white pigment used in a bone china and a fabricating technology for the blue-and-white bone china. The blue-and-white pigment used in the bone china is prepared by mixing following components in percentage by weight: 30%-70% of the pigment, 10%-30% of a bone china blank, 10%-40% of glaze and 1%-3% of methylcellulose. The fabricating technology of the blue-and-white bone china comprises the steps that a bone biscuit which is subjected to biscuit firing is coated with the blue-and-white pigment which is prepared in a ratio and used in the bone china, and then the bon biscuit is placed in a kiln for color baking. According to the invention, the pigment is matched with the bone china blank and the glaze for usage, a mixture with the pigment is drawn on the biscuit and subjected to high temperature color baking, and the combination degree of bone china blank components in the mixture and the bone china biscuit is good, so that the pigment in the mixture is attached to the bone china biscuit excellently; meanwhile, contained components of the glaze enhance the fusion degree with sizing glaze; and consequently, the defect of permeation of the blue-and-white on the bone china in conventional processing and formulas is overcome excellently.

Description

technical field [0001] The invention belongs to the field of ceramic materials, in particular to a component of a blue and white color material for bone china and a process for making blue and white bone china using the blue and white color material for bone china. Background technique [0002] As a unique pattern on traditional Chinese porcelain, blue and white occupies an important place in the field of porcelain. Traditional Chinese blue and white is often formed by drawing ultramarine blue and cobalt blue materials and other components on white porcelain through a specific ratio, showing smooth and distinct chrome green and cobalt blue, and is loved by the world. The components of the existing blue and white color material are cobalt blue color material, ultramarine blue color material, methyl cellulose and cosolvent. Existing blue and white technology is only applied on white porcelain. Because the density of white porcelain is relatively high, it is not easy to sprea...

Problems solved by technology

[0006] In order to solve the problem in the prior art that it is difficult to burn smooth and uniform blue-and-white patterns on bone china due to the penetration of pigments, the present invention proposes a method that can solve the defect of blue-and-white penetration on bone china, so that it can be painted on bone china. The blue-and-white pattern on the porcelain is smooth and uniform, and the blue-and-white coloring material used for bone china and the blue-and-white bone china manufacturing process using the blue-and-white coloring material
