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 blue-bottomed mottled composite Tang Jun glaze 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

[0032] The process of preparing Jun Porcelain by using Tang Jun Glaze compounded with mottled blue background 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 sl...

[0044] The process of preparing Jun Porcelain by using Tang Jun Glaze compounded with mottled blue background includes the following steps:

[0045] Step 1. Firing the plain tire

[0046] 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 300 meshes; the obtained mud is poured into a plain tire, and the plain tire is placed in a kiln to dry at 880°C for 10 hours, and cooled to room temperature with the furnace, and the fired plain tire is obtained for use;

[0047] Step 2. Prepare the blue base glaze

[0048] Put 37 parts of yellow feldspar, 11 parts of calcite, 11 parts of quartz stone, 12 parts of black medicine soil, 22 parts of copper ore and 0.8 part of cobalt oxide into the ball mill, add water of equal quality to it, and ball mill it into a slurry ...

Abstract

The invention provides a blue background and mottled spot composite Tang jun glaze and a technology for preparing jun porcelain through the same. Firstly, casing body raw materials are smashed and molded, and a prime casing is fired; then, the prime casing is soaked into blue background glaze slurry to be subjected to glazed, and after the blue background glaze slurry attached to the surface of the prime casing is dried, mottled spot glaze slurry is applied to local points on the surface of the prime casing; after the mottled spot glaze slurry attached to the surface of the prime casing is dried, the prime casing is placed in a kiln to be fired, and then the blue background and mottled spot composite Tang jun glaze jun porcelain is obtained. According to the blue background and mottled spot composite Tang jun glaze and the technology for preparing the jun porcelain through the same, due to the fact that iron elements, copper elements and cobalt elements are added in the blue background glaze according to specific proportions and a secondary glazing mode is used, glaze layer hacking is uniform and is not prone to bursting. The technology breaks through the overglaze color or underglaze color coloring technology adopted by a common mottled spot porcelain, the economic value of the jun porcelain is creatively increased on the aspects of glaze colors and a coating, the technology represents the advanced level of the manufacturing technology in China, and the social value of the jun porcelain is improved.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a blue-bottomed 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 ...
