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 background and white spots and uses it to prepare Jun porcelain. In the process of porcelain, the specific glaze color is fired by fixing the formula of the glaze, and the position of the white spot effect is fixed by the way of secondary glazing. At the same time, specific ingredients are added to the formula of the glaze, so that the glaze layer Open slices evenly but not easy to burst

Embodiment 1

[0032] The process of preparing Jun porcelain with blue and white white composite Tang Jun glaze includes the following steps:

[0033] Step 1. Firing the plain tire

[0034] Mix 65 parts of kaolin, 20 parts of soda stone, 8 parts of Mujie clay and 7 parts of quartz sand evenly, and stir with water at a mass ratio of 1:1 to obtain a mixture; grind the mixture into a slurry with a ball mill, and finely grind it for 80 minutes. The fineness reaches 250 mesh; the obtained mud is hand-drawn to make a plain tire, and the plain tire is put into a kiln to dry at 860°C for 10 hours, and then cooled to room temperature with the furnace, and the fired plain tire is obtained. ;

[0035] Step 2. Prepare the blue base glaze

[0036] Put 35 parts of yellow feldspar, 10 parts of calcite, 10 parts of quartz stone, 10 parts of black medicine soil, 18 parts of copper ore and 0.2 parts of cobalt oxide into the ball mill, add water of equal quality to it, and ball mill it into a slurry with a f...

Abstract

The invention discloses a complex tang-dynasty jun glaze with white spots in blue 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 blue for glazing; applying slurry of the glaze with white spots in surface points of the plain carcass after the slurry of the glaze in blue 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 white spots is dried, thereby obtaining the complex Tang-dynasty jun glaze with white spots in blue. According to the Tang-dynasty jun glaze with white spots in blue 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 a glaze material of glaze in blue, and the position of the glaze with white 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 blue white white 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". It is a unique national treasure porcelain in Huangdao Town, Pingdingshan City, Henan Province. Simple shapes, exquisite craftsmanship, complex glaze matching, the magical kiln transformation of "one color in the kiln, and thousands of colors in the kiln", lakes and mountains, clouds and mist, human beings, animals, flowers, birds, insects and fish, etc. The graphic colors and wonderful charm are endlessly changing. The first of the "Five Famou...
