Sapphire blue glaze porcelain with gold-thread and iron-wire crackle network and preparation method of sapphire blue glaze porcelain

Abstract

The invention provides sapphire blue glaze porcelain with a gold-thread and iron-wire crackle network and a preparation method of the sapphire blue glaze porcelain. According to the sapphire blue glaze porcelain with the gold-thread and iron-wire crackle network, a preform body of the sapphire blue glaze porcelain with the gold-thread and iron-wire crackle network is prepared from red earth, waste glass, dolomite, sodium tripolyphosphate, wollastonite, feldspar and pyrophyllite; a glaze material is prepared from expansive soil, feldspar, quartz, copper carbonate, lithium carbonate and yellow soil. According to the sapphire blue glaze porcelain with the gold-thread and iron-wire crackle network, formulae of the preform body and the glaze material are changed respectively, a unique firing method is combined, so that the porcelain obtained after firing has a very high decorative effect different from a traditional glaze effect and is particularly suitable for being used as a home decorative ornament and artware, and a prepared product has a unique artistic effect and a high additional value; besides, compared with traditional cracked glaze, the sapphire blue glaze porcelain with the gold-thread and iron-wire crackle network has the advantage that the preform body and the glaze material both utilize low-price raw materials, is fired at low temperature, fuel-saving, energy-saving and environment-friendly and has positive social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a sapphire blue gold wire iron wire glazed porcelain and a preparation method thereof. Background technique [0002] Crackle glaze refers to the fine cracks on the glaze layer of ceramic products, which makes ceramic products have specific artistic effects and is favored by people. There are two reasons for the cracking of the glaze surface: one is that the body mud extends along a certain direction during molding, which affects the arrangement of molecules; Cracking was originally a shortcoming in porcelain firing at first, but the crackle glaze produced by people mastering the law of cracking has become a special decoration of porcelain. The Ru, Guan, and Ge kilns in the Song Dynasty all had this kind of product. The cracked glazes of Ru, Guan, and Ge kilns had obvious characteristics. The colors include eel blood, gold wire and iron wire, light yellow caviar pa...

AI Technical Summary

Problems solved by technology

[0003] The traditional cracked glaze has high firing temperature, unstable glaze effect, and single glaze effect, which cannot meet the needs of consumers with different personalities; in addition, most existing cracked glazes have long firing time and high firing temperature, and the production It consumes more fuel, the production efficiency is relatively low, and the production cost is high

In order to solve the above problems, the invention patent application with the application publication number of CN 105060938A discloses a cracked glaze and its production method. The cracked glaze reduces the glaze firing temperature to 1150-1200°C through the adjustment of the glaze components, and through the color Penetrate into the cracks to color the cracks, but this kind of cracked glaze is fired at a medium temperature, and the firing temperature can be further reduced, and only the color of the cracks will be changed, and the overall effect on the glaze surface will not be changed significantly.
