A carbon-absorbing crack glaze for firewood-fired pottery, its preparation method, its prepared ceramics, and its preparation method

Abstract

The invention relates to the field of pottery clay, a pottery clay preparation method, ceramic and a ceramic preparation method and in particular relates to a carbon-adsorption crack glaze material for firewood fired pottery and a preparation method thereof as well as ceramic prepared from the carbon-adsorption crack glaze material and the ceramic preparation method. The glaze material is preparedfrom the following components in parts by weight: 35 to 42 parts of kaolin, 16 to 22 parts of sodium carbonate, 10 to 13 parts of ball clay, 1 to 3 parts of salt, 7 to 10 parts of orthoclase, 5 to 7parts of zirconium silicate, 1 to 2 parts of cryolite and 1 to 2 parts of cellulose gum. Sodium carbonate in the glaze material adsorbs a lot of elemental carbon in a reduction atmosphere of a firewood firing kiln; a glaze surface is cracked through the salt and the kaolin; the ceramic glaze surface prepared from the carbon-adsorption crack glaze material forms carbon-adsorption and crack characteristics so that the ceramic has unique aesthetic value.

Description

technical field [0001] The invention relates to the fields of pottery clay, a preparation method of pottery clay, ceramics and ceramic preparation methods, in particular to a carbon-absorbing crack glaze for firewood-fired pottery, a preparation method thereof, ceramics prepared therefrom, and a ceramic preparation method. Background technique [0002] Firewood firing is an ancient firing method. Wood is the main fuel of the kiln. When firing pottery, the porcelain body is covered to isolate the wood ash from the fire and avoid direct contact with it, so that the glaze color of the product remains consistent. The traces of ash falling on the glaze or fire on the carcass are not appreciated in the orthodox porcelain making standards of ancient Chinese society as long as the technology allows it, and are regarded as "flaws". However, under the conditions of modern porcelain making and firing technology being extremely successful, a modern ceramic art creation "firing concept" ...

Problems solved by technology

The color and shape of the surface of the existing firewood pottery are relatively single, and it is impossible to express the artistic beauty of porcelain through rich colors
