Complex Tang-dynasty jun glaze with blue spots in black and process for preparing jun porcelain by use of complex Tang-dynasty jun glaze

Abstract

The invention discloses a complex tang-dynasty jun glaze with blue spots in black and a process for preparing jun porcelain by use of the complex Tang-dynasty jun glaze. The process comprises: firstly crushing and molding carcass raw materials, and firing the carcass raw materials into plain carcass; then, immersing the plain carcass into slurry of glaze in black for glazing; applying slurry of the glaze with blue spots in surface points of the plain carcass after the slurry of the glaze in black adhered on the surface of the plain carcass is dried in air; and putting the plain carcass into a kiln for firing after the slurry of the glaze with blue spots is dried, thereby obtaining the complex Tang-dynasty jun glaze with blue spots in black. According to the Tang-dynasty jun glaze with blue spots in black and the process for preparing jun porcelain by use of the complex Tang-dynasty jun glaze disclosed by the invention, an iron element, a copper element and a cobalt element in special proportion are added into glaze in black, are fired at a high temperature to form black glaze which is stable in color generation, uniform in color and luster and full of a jade texture, and the position of the glaze with blue spots is fixed by use of a secondary glazing mode. A coloring process of overglaze color or underglaze color adopted by general piebald porcelains is broken through; economic value of the jun porcelain is increased through innovation in glazing color and coating; and the jun porcelain, which is a Chinese characteristic, also represents advanced level of the production process in China, thereby increasing the social value of the jun porcelain.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a black-bottom blue-spot composite Tang Jun glaze and a process for preparing Jun porcelain using the same. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. Famous for its unique kiln transformation art, it has the reputation of "gold is priceless and Jun porcelain is priceless" and "a family is rich, not as good as a piece of Jun porcelain".

Problems solved by technology

[0004] In order to solve the problems that the glaze color and pattern are difficult to control during the firing process of Jun porcelain, and the glaze layer is easy to burst and crack uneven when Jun porcelain comes out of the kiln, the present invention proposes a black-bottomed blue-spot composite Tang Jun glaze and its application. The process of preparing Jun porcelain uses a fixed glaze formula to fire a specific glaze color, and uses the method of secondary glazing to fix the position of the blue spot effect, and at the same time adds specific ingredients to the glaze formula , so that the glaze layer splits evenly but is not easy to burst
