Embodiment

[0028] The specific steps for firing colorless jadeite glazed Ru porcelain with the modern firing process of Ru porcelain are as follows:

[0029] 1. Raw material processing

[0030] First crush the white agate stone and pass through a 100-mesh sieve to obtain the white agate powder. Weigh 0.15 parts by weight of the white agate powder, and weigh equimolar amounts of sodium silicate and aluminum silicate. The total weight is 2 parts by weight.

[0031] 2. Raw material melting

[0032] Put 1 / 2 weight part of sodium silicate and 1 / 2 weight part of aluminum silicate into a high-temperature furnace for sintering after ball milling, where the sintering heating rate is 5°C / min, heat up to 1400°C for 2 hours, and take it out after cooling The sample was ground and passed through a 100-mesh sieve to obtain raw material frit powder.

[0033] 3. Glaze slurry

[0034] Put 1 part by weight of high-purity water in the constant temperature glaze slurry tank, set the temperature of the co...

Abstract

The invention discloses a jadeite vitreous glaze and a glazing method, and belongs to the technical field of modern ceramic preparation. According to the technical scheme, the selected raw materials of the glaze comprise: sodium silicate, aluminum silicate, white agate, a chromogenic ionic oxide and the like, wherein the main materials Na2SiO3 and Al2O3SiO2 react to generate jadeite (NaAl(Si2O6))vitreous matter. According to the invention, the main materials select Na2SiO3 and Al2O3.SiO2, the two components react to generate a colorless jadeite (NaAl(Si2O6)) vitreous new glaze species, and the colorless jadeite (NaAl(Si2O6)) vitreous new glaze species is as clear and transparent as glass and crystal; and the colorless jadeite vitreous new glaze can be added with a chromogenic ionic oxideaccording to a target to prepare various glaze colors.

Description

technical field [0001] The invention belongs to the technical field of modern ceramic preparation, and in particular relates to an emerald vitreous glaze and a glaze application method. Background technique [0002] my country's ceramics have a long history and have a glorious history and unique achievements in the world. They are the witness of the brilliant civilization of the Chinese nation. Porcelain comes from pottery. According to the kiln mouth of porcelain, there are as many as 25 kinds in China. Among them, glaze color is also an important criterion for classifying porcelain, which can be divided into two categories: single-color glaze and colored glaze porcelain. In the development of ceramics, it has experienced the process from single-color glaze to multi-color glaze (color glaze). Monochromatic glazes include green glazes (pink blue, sky blue, bean green, etc.), white glazes (sweet white, blue white), red glazes (ji red, ox blood red, cowpea red, etc.), blue gla...
