Problems solved by technology

The formation of the color tone of celadon is mainly caused by a certain amount of iron oxide contained in the glaze, which is roasted in a reducing flame atmosphere. However, some celadon is yellow or yellowish-brown in color due to impure iron content and insufficient reducing atmosphere. Due to the strong fluidity and low yield of celadon, most of the celadon glazes currently produced are made of industrially processed ceramic minerals. Local natural ceramic minerals are rarely used because the content of natural ceramic minerals is unstable. Cannot be mass produced

Abstract

The invention belongs to the technical field of artistic porcelain glaze and particularly relates to artistic celadon glaze as well as a preparation method and a sintering technology thereof. The celadon glaze is prepared from the following raw materials in percentage by weight: 60 to 65 percent of base glaze and 35 to 40 percent of auxiliary glaze, wherein the base glaze is prepared from Guodingmountain feldspar in Pingdingshan College; the auxiliary glaze is prepared from the following raw materials in percentage by weight: 29 percent of calcite, 54 percent of quartz, 14 percent of zinc oxide and 3.0 percent of tin oxide. According to the preparation method disclosed by the invention, the celadon glaze with the regional characteristics of Pingdingshan City is prepared by utilizing localspecial ceramic minerals of Pingdingshan; the preparation method has the advantages of low production cost and suitability for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of artistic celadon glaze, and in particular relates to an artistic celadon glaze, a preparation method and a firing process thereof. Background technique [0002] Celadon is a kind of famous traditional Chinese porcelain. It is made by applying celadon glaze (green glaze with iron as the colorant) on the body and firing in reducing flame. The name "celadon" was first seen in "Baibao Zong "Zhen Ji" (written by Anonymous in the Southern Song Dynasty), in which there is a special item of celadon, in which it is said that the Ru kiln "comes from the new kiln in the north, and the one who repaired the inner division and burned it himself" is an official kiln in the Northern Song Dynasty, and the old kiln should be the firewood kiln. Celadon wares almost ceased to exist in the Southern Song Dynasty. The words "Ru kiln soil veins are charming" and "those with chicken claw patterns are serious" are the characterist...
