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 unevenly when it comes out of the kiln, the present invention proposes a composite Tang Jun glaze with black background mottled and its preparation The craft 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 mottled effect. At the same time, specific ingredients are added to the glaze formula, making The glaze layer splits evenly but is not easy to burst

Embodiment 1

[0033] The process of preparing Jun Porcelain by using the compound Tang Jun Glaze with mottled black background includes the following steps:

[0034] Step 1. Firing the plain tire

[0035] 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. ;

[0036] Step 2. Prepare the black base glaze

[0037] Mix 60 parts of feldspar, 5 parts of quartz stone, 12 parts of calcite, 5 parts of iron ore, 5 parts of black medicine and 0.2 part of iron oxide into the ball mill, add water of equal quality to it, and ball mill it into a material with a fi...

Abstract

The invention provides black-base mottled composite Tang jun glaze and a process for preparing jun porcelain through the black-base mottled composite Tang jun glaze. Firstly, base raw materials are smashed and molded, a plain base is fired, the plain base is immersed in slurry of black-base glaze for glazing, after the slurry of the black-base glaze is attached to the surface of the plain base and the plaint base is aired, slurry of mottled glaze is arranged on part of the surface of the plain base in a spot application mode, the plain base is placed in a kiln to be fired after being aired, and then the black-base mottled composite Tang jun glaze jun porcelain is obtained. According to the black-base mottled composite Tang jun glaze and the process for preparing the jun porcelain through the black-base mottled composite Tang jun glaze, an iron element at a specific ratio is added to the black-base glaze, black glaze which is stable in color generation, uniform in color and luster and rich in jade texture feeling is obtained through high-temperature firing, the mottled glaze is fixed in a secondary glazing mode, an overglaze color or underglaze color coloring process adopted by ordinary mottled porcelain is broken through, the economic value of the jun porcelain is increased through innovation in glaze colors and coatings, the jun porcelain stands for the feature of China and also represents the advanced level of the craftsmanship in China, and the social value of the jun porcelain is increased.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a black-bottom mottled 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 F...
