Complex Tang-dynasty jun glaze with blue spots in white 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 white 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 white for glazing; applying slurry of the glaze with blue spots in surface points of the plain carcass after the slurry of the glaze in white 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 white. According to the Tang-dynasty jun glaze with blue spots in white and the process for preparing jun porcelain by use of the complex Tang-dynasty jun glaze disclosed by the invention, milky white glaze is presented in the process of firing by adding zircon into a formula of the glaze in white; 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 composite Tang Jun glaze with blue spots on a white background and a process for preparing Jun porcelain using the same. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty and is one of the five famous kiln porcelains in the Song Dynasty. It is a treasure of the traditional porcelain making of the Han nationality and is called a national treasure. Known all over the world for its unique art of kiln transformation, it is known as "gold is priceless" and "a family is worthless, not as good as a piece of Jun porcelain". It is a unique national treasure porcelain in Huangdao Town, Pingdingshan City, Henan Province. The quaint shapes, exquisite craftsmanship, complex glazes, the magical kiln change of "one color in the kiln and the kiln out of the kiln", lakes and mountains, clouds and mists, people, animals, flowers, birds, insects, and other endlessly...

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 composite Tang Jun glaze with blue spots on a white background and its preparation. The craftsmanship of Jun Porcelain uses a fixed glaze formula to produce a specific glaze color, and uses the method of secondary glazing to fix the position of the blue spot effect. At the same time, specific ingredients are added to the glaze formula, so that The glaze layer splits evenly but is not easy to burst
