Manufacturing process and application of Thangka

Abstract

The invention discloses a manufacturing process and application of Thangka, and the manufacturing process comprises the following steps: 1, carrying out impurity removal, shaping, airing and fine trimming processes on a kaolin raw material, and then carrying out first bisque firing and second firing to form a white body high-temperature porcelain plate; 2, fixing lines; 3, coloring for the first time, and firing for the fourth time; 4, coloring for the second time, and firing for the fifth time; 5, coloring again, balancing chromatic aberration, and checking leakage points; and firing for thesixth time; 6, firing at high temperature for the seventh time; 7, drawing gold and drawing by using pure gold powder; and finally, firing the fixed gold powder for the eighth time; and 8, after firing is completed, carrying out polishing and glaze sealing treatment on sea sand and agate tools; and finally detecting a framed finished product. According to the high-temperature pink ceramic preparedby the method disclosed by the invention, the pigment is fused into the ceramic under the action of high temperature, the color is developed in the ceramic, the color contains the ceramic, the colorand the ceramic are integrated, and the Thangka has the advantages of underglaze, in-glaze and pink decoration, and is corrosion-resistant and fadeless.

Description

technical field [0001] The invention relates to the technical field of ceramic surface decoration, in particular to a production process and application of Thangka. Background technique [0002] Pastel porcelain is a kind of overglaze color, one of the four famous porcelains in China, also called "soft color", which is based on the use of powder and rendering techniques in Chinese painting. A layer of glass white is applied, then painted with colored materials, and baked in the oven. In terms of color preparation, we also borrowed the multi-color preparation technique of franc color to create a new variety of porcelain with low-temperature overglaze color. These ceramics are rich in color, exquisite and beautiful. Because a painting material containing lead, silicon, and arsenic must be used on the glaze of ceramics, commonly known as glass white, it mainly acts as a flux. After that, it becomes white glass, with the characteristics of opacity and bright surface. Pastel p...

Problems solved by technology

[0003] The overglaze color and underglaze color of pastel ceramics made by the current technology have different colors due to different temperatures, do not blend, the color is not bright enough, easy to fade, and the content of heavy metals is high, which is harmful to human health.
