Crystal ice crack porcelain and preparation method thereof

Abstract

The invention provides crystal ice crack porcelain and a preparation method thereof, and relates to the technical field of ceramics. The crystal ice crack porcelain comprises a blank and glaze, and the glaze comprises the following raw materials in parts by weight: 28-52 parts of potassium feldspar, 28-52 parts of albite, 10-20 parts of limestone, 2-4 parts of Zijin clay, 0.5-1.5 parts of fluorite, 0.5-1.5 parts of zinc oxide and 2-6 parts of barium carbonate. The preparation method comprises the following steps: grinding blank raw materials, adding water for wet grinding, preparing blank mud, drying and molding, and sintering in a kiln to obtain a biscuit firing blank; mixing the raw materials of the glaze, performing wet ball milling on the ballstone, the mixed raw materials of the glaze and water, and grinding to obtain glaze slip; glazing slurry is applied to the cooled biscuit firing blank, and the bottom foot of the biscuit firing blank is scraped and washed; the glazed biscuit firing blank is put into a kiln to be fired, and the crystal ice crack porcelain is obtained after firing. The crystal ice crack porcelain has the advantages of complete and attractive patterns, uniform distribution and high glaze glossiness.

Description

technical field [0001] The present application relates to the technical field of ceramics, and in particular, to a crystal ice cracked porcelain and a preparation method thereof. Background technique [0002] China's porcelain culture has a long history. Celadon is famous for its delicate porcelain, dignified and simple shape, and lustrous and warm color. It has the reputation of "the flower of porcelain". Celadon originated from the primitive porcelain in the Shang Dynasty, and reached its peak in the Song Dynasty. In the course of 3,000 years of development, celadon has grown from birth to maturity. The texture of ice is a symbol of the noble character of the Chinese nation. In the course of the development of Chinese civilization, it is a vivid national cultural symbol. [0003] Ice cracked porcelain is actually a kind of slanted cracked glaze porcelain. The basic principle is that the expansion coefficient of the tire glaze is inconsistent, creating various forms of cra...

AI Technical Summary

Problems solved by technology

However, due to the extremely difficult firing of ice-cracked porcelain, very few ice-cracked porcelains from ancient kilns have been handed down, and its firing technology has been lost since the Southern Song Dynasty.

For many years, many domestic experts have been exploring the firing method of ice cracked porcelain. Although they have made some achievements, there are always various shortcomings. The distribution in the glaze layer is uneven and disorderly. There are few ice cracks on a product and the plum blossom ink pattern is the main pattern and there are many fine grains. Moreover, the size of the air bubbles in the glaze is unevenly distributed, which makes the entire glazed surface of the porcelain obscure and dull. dull
