Problems solved by technology

[0003] In the production of Jun porcelain, although the current technology has made great progress, there are still some defects. In the production process of Jun porcelain, from the selection of materials to the firing of finished products, there are dozens of production processes. Shen will also cause all previous efforts to be wasted, which is why the output of Jun porcelain has been extremely low all the time.
[0004] The traditional firing process of Jun porcelain includes pre-firing, firing in an oxidizing atmosphere, firing in a reducing atmosphere, and the final cooling process. The glaze color of fired Jun porcelain tends to be dark and not bright, which affects the aesthetics

Embodiment 2

[0038] The process of preparing Jun porcelain using Tianmu sauce gold glaze includes the following steps:

[0039] Step 1. Firing the plain tire

[0040] 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 meshes; the obtained mud is hand-drawn to make a plain tire, and the plain tire is put into 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. ;

[0041] Step 2. Prepare the glaze

[0042] Mix 22 parts of yellow feldspar, 12 parts of albite, 0.8 part of quartz, 0.6 part of kaolin, 0.5 part of soda stone, 0.8 part of talc, 1.4 parts of bone ash and 0.8 part of iron ore into a ball mill, add water of equal quality to it and ball mill first Make a slurry with a fineness of 350 me...

Abstract

The invention discloses a process for firing jun porcelain by the aid of temmoku brown golden glaze. The method includes four steps of pre-firing plain bodies with the temmoku brown golden glaze in a kiln; firing the plain bodies in oxidizing atmosphere; firing the plain bodies in reducing atmosphere; cooling the plain bodies to obtain the jun porcelain with the temmoku brown golden glaze. A step of preserving heat is further carried out between the step of firing the plain bodies in the reducing atmosphere and the step of cooling the plain bodies. The step of preserving the heat includes reducing the internal temperature of the kiln from the original 1280 DEG C to 1260-1270 DEG C within 5 min; preserving the heat for 1 h. The process for firing the jun porcelain by the aid of the temmoku brown golden glaze has the advantages that iron elements and sodium elements in the glaze interact with one another, the step of preserving the heat is additionally carried out in a firing procedure, accordingly, glaze colors of fine golden temmoku patterns appear on deep red ground colors, the glaze and the process are greatly innovated, and an economic benefit of the jun porcelain can be increased; the advanced level of manufacturing processes in China are represented by the jun porcelain which is a characteristic of China, and social value of the jun porcelain can be increased.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a process for firing Jun porcelain with Tianmu sauce golden glaze. 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 Famous Porcelains". [0003] In the pro...
