example 1

[0017] The weight percentage composition of the cracked glaze of the official kiln imitation:

[0018] Sambo 23% Feldspar 45% Kaolin 5% Quartz 15% Dolomite 5% Lime 5% Zircon 2%. After carefully selecting various glazes according to the requirements of the formula, mix them evenly, with a ball stone: glaze: water ratio of 2:1:0.8, put it into the ball milling equipment and grind to a fineness of 100 mesh after 16 hours of ball milling time, and filter The glaze slurry can be formed.

[0019] The chemical composition of the raw materials of the glaze

Embodiment 1

[0021] Example 1 The ingredient weight percentage composition of imitating official kiln cracked glaze clay: Nangang billet 30%, Sanbao billet 10%, kaolin 30%, remaining dry billet 15%, and Qimen 15%. After beneficiation, beneficiation, crushing, elutriation, sedimentation, stale (slurry) 80 mesh fineness filtration, drainage and other processes, it becomes green mud.

[0024] After forming the cracked porcelain body of the imitation official kiln, it is dried and loaded into the kiln. After 7 hours of low fire, the kiln temperature rises to 880℃ to stop firing, and the green body is discharged out of the kiln after natural coo...

Embodiment 2

[0027] Example The official kiln cracked glaze composition is composed of 20% Sambo, 40% feldspar, 10% kaolin, 10% quartz, 10% dolomite, 7% lime, and 3% zircon by weight. After carefully selecting various glazes according to the requirements of the formula, mix them evenly, with a ball stone: glaze: water ratio of 2:1:0.8, put it into the ball milling equipment and mill it into fine grinding for 16 hours and filter it into a glaze at 100 mesh. Pulp is enough.

[0028] The chemical composition of each raw material of the glaze is the same as in Example 1.

Abstract

The invention discloses a formula of an official kiln imitated crackle glaze material, wherein a small deal of zirconite is introduced to the formula, and through the reasonable matching ratio of all components, the glaze material is wide in adaptability, good in heat stability as well as gentle and jade-like in glazing color. The invention also discloses a method for manufacturing an official kiln imitated crackle glaze ceramic product by using the official kiln imitated crackle glaze material, wherein the ball milling fineness of the glaze material is mastered, and the ceramic blank biscuit firing and glaze firing times, temperature and glaze applying thickness are controlled, so that large official kiln crackle pieces appear after a glazing surface is subjected to thermal expansion and cold shrinkage. The method has the characteristics of science, reasonability, easiness for implementation, high rate of finished products, good ceramic quality, clear, simple, unsophisticated and elegant crackle pieces and uniform glaze layer crackles and can form the visual artistic effect that the jade-like stone is as thick as accumulated fat.

Description

Technical field [0001] The invention belongs to the technical field of ceramic product manufacturing, and specifically relates to a method for manufacturing an official kiln cracked glaze and a method for manufacturing an official kiln cracked glaze ceramic product. Background technique [0002] Jingdezhen, Jiangxi is a famous porcelain capital at home and abroad, and its ceramic products are dazzling. Imitated official kiln products of past dynasties are sought after by collectors. Among them, official kiln cracked glaze ceramics have uniform cracks and rich glaze color. The obtained imitating official kiln cracked finished product has inconsistent thermal expansion coefficients between the green body and the glaze, and the shrinkage coefficient of the green body and the glaze is different during the cooling process, and cracks are generated on the finished glaze surface. The cracks on the glaze of Ge Kiln products are actually a kind of defect, but they are cleverly used as de...
