Abstract

The invention relates to the technical field of porcelain processing and particularly relates to a method for preparing a multicolored jade-carved ceramic. The method comprises the following steps: a, preparing a ceramic green body; b, preparing glaze water; c, preparing colored glaze water; d, applying the glaze water obtained in the step b on the green body to obtain a green body with a transparent glaze; e, applying the colored glaze obtained in the step c to the green body with the transparent glaze to obtain a green body with the colored glaze; f, carrying out enclosed oxidization firing on the green body with the colored glaze in the step e, firstly firing at a temperature of 300-1290 DEG C for 6-8 hours, then firing at a constant temperature of 1290 DEG C for 40 minutes and finally naturally cooling to obtain the final product ceramic. The method disclosed by the invention has the following beneficial effects: by virtue of adding pigment in a glazing slurry, multicolored patterns present after the green body is fired and no lead cadmium in the glaze and no toxic effect are achieved; since the colored ceramic is obtained by virtue of a single firing process, decorative processing steps such as decal and colored painting are omitted and the firing step is reduced, so that the processing efficiency is greatly improved and the cost is saved by up to 20%.

Description

technical field [0001] The invention relates to the technical field of porcelain processing, in particular to a method for preparing multi-color carved jade porcelain. Background technique [0002] At present, the processing method of painted porcelain is mainly realized through the following steps in turn: A embryo making: beating the porcelain clay, and making green embryos according to conventional methods; B bisque firing: bisque firing the raw embryos according to conventional methods, that is Firing at a temperature of 780 degrees for 4 to 5 hours; C ceramic decoration: decorate the plain embryo with various patterns, such as decals and colored paintings on the plain embryo; D glazing: glaze the decorated green embryo according to the conventional method ; E glaze firing: the glazed raw embryos are sealed in a kiln and fired at a temperature of 1270-1310 degrees for 8-11 hours, and then cooled naturally to form finished porcelain. [0003] Generally, the colored porce...
