Problems solved by technology

Because the color formation mechanism of Ru porcelain is that the feo3 element contained in the glaze produces a single blue glaze under a reducing atmosphere, which leads to the single glaze color of Ru porcelain
A single glaze color is difficult to meet the multicultural aesthetic needs of people, which narrows the choice of Ru porcelain collectors, thus limiting the value of Ru porcelain collectors

Embodiment 1

[0020] A firing method for painted Ru porcelain, comprising the following steps:

[0021] 1) Make the biscuit, then apply glaze on the biscuit and reserve the unglazed painted area, the biscuit is made of mud and obtained after firing at 700°C for 4.5 hours;

[0022] 2) Sinter the bisque with the unglazed painted area reserved in step 1) at 1260°C for 16 hours to obtain the matrix, and set aside;

[0023] 3) Use low-temperature pigments to paint in the painted area on the substrate. After painting, burn at 600°C for 5 hours and cool to get the finished product.

Embodiment 2

[0025] A firing method for painted Ru porcelain, comprising the following steps:

[0026] 1) Make the biscuit, then apply glaze on the biscuit and reserve the painted area without glazing. The biscuit is made of mud and obtained after firing at 900°C for 3.5 hours;

[0027] 2) Sinter the bisque with the unglazed painted area reserved in step 1) at 1280°C for 15 hours to obtain the matrix, and set aside;

[0028] 3) Use low-temperature pigments to paint in the painted area on the substrate. After the painting is completed, fire at 800°C for 4 hours and then cool to obtain the finished product.

Embodiment 3

[0030] A firing method for painted Ru porcelain, comprising the following steps:

[0031] 1) Make the biscuit, then apply glaze on the biscuit and reserve the unglazed painted area, the biscuit is made of clay after firing at 800°C for 4 hours;

[0032] 2) After glazing the body with the reserved painted area, sinter it at 1270°C for 15.5 hours to obtain the matrix and set it aside;

[0033] 3) Use low-temperature pigments to paint in the painted area on the substrate. After the painting is completed, fire at 700°C for 4.5 hours and then cool to obtain the finished product.

[0034] The above is the basic implementation of the present invention. In order to prevent the painting layer of the painted area from wearing and falling off, before step 3 of the above embodiment is used for painting with low-temperature pigments, the auxiliary agent is evenly applied to the painted area in advance. The auxiliary agent is 60-80 A mixture of purpose rosin powder, 60-80 purpose iron oxid...

Abstract

The invention provides a method for firing painted Ru porcelain. The method comprises the steps of firstly making a biscuit, then glazing on the biscuit and reserving a colored drawing region, sintering the glazed biscuit reserved with the colored drawing region for 15-16 hours at 1260-1280 DEG C to obtain a matrix, painting in the colored drawing region on the matrix by using low temperature pigment, sintering the matrix for 4-5 hours at 600-800 DEG C after painting, and cooling to obtain a finished product. According to the method provided by the invention, a porcelain surface is painted by pigment and is then sintered and cured to form a painting on the Ru porcelain surface, thereby not only improving the aesthetic level of the Ru porcelain, but also greatly enhancing the collection and exhibition values of the Ru porcelain; meanwhile, in order to prevent the drop and attrition of the painting layer, a layer of additive is firstly brushed before painting, and the additive can carry pigment to react with components in the porcelain during high temperature sintering, so as to cure the pigment on the porcelain surface to prevent the drop and attrition of the painting layer.

Description

technical field [0001] The invention relates to the firing field of ceramics, in particular to a firing method of painted Ru porcelain. Background technique [0002] Ru Porcelain is one of the five famous porcelains in my country. Its manufacturing process was lost for a time, but after hard research by technicians, production has now resumed. The current production process of Ru porcelain is generally to make clay body, biscuit firing, glaze firing after glazing, cooling and then exiting the kiln to obtain the product. Because the color formation mechanism of Ru porcelain is that the feo3 element contained in the glaze produces a single blue glaze under a reducing atmosphere, which leads to the single glaze color of Ru porcelain. A single glaze color is difficult to meet the multicultural aesthetic needs of people, which narrows the choice of Ru porcelain collectors, thus limiting the value of Ru porcelain collectors. Contents of the invention [0003] In order to solve...
