Mixed ash glaze, preparation process and pottery firing method thereof

Abstract

The invention belongs to the technical field of pottery processing equipment, and particularly discloses a mixed ash glaze which comprises the following components in parts by weight: 35-40 parts of pine ash, 30-35 parts of Chinese chestnut bud ash, 15-25 parts of slaked lime, 5-10 parts of silicon dioxide and 3-5 parts of ferric oxide. The raw materials of the glaze comprise the pine ash, the Chinese chestnut bud ash, the slaked lime and the like which are low in price and easy to obtain, the pine ash and the Chinese chestnut buds are wastes, the environment-friendly value is better, and the glaze is sintered in an electric kiln or an air kiln at medium temperature, so that the sintering energy consumption and the sintering time can be effectively reduced, meanwhile, the production cost of the material is greatly reduced, and the economic benefit and the market competitiveness are improved.

Description

technical field [0001] The invention relates to the technical field of pottery processing, in particular to a mixed gray glaze, a preparation process and a firing method for pottery. Background technique [0002] my country has a long history of pottery making. Ancient Chinese kiln workers discovered that the glassy substance formed by melting plant ashes and clay at high temperature was called "kiln sweat" at that time, which is the origin of glaze. On this basis, our ancestors began to add various natural seasonings, blended ever-changing pottery glazes, and produced simple and natural pottery products, but most of these glaze recipes have been lost. Over a thousand years ago, Wujin glaze represented by Fujian Jianyang kiln in Song Dynasty, white glaze mainly composed of northern Ding kiln in Sui Dynasty, and Longquan green glaze developed on the basis of northern Ru kiln were formed. a famous representative. [0003] Glazed pottery, formed by burning plants and falling ...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no technology at home and abroad to use pine ash mixed with chestnut bract ash to make pottery glaze. It is reported that there are artists in Taiwan, China, who imitated the ancients when they fired pottery and dropped plant ash on pottery to form ash glaze, but it was not configured well. Gray glaze, and the type and proportion of plant ash used have not been disclosed. It can be seen that the key technical content of the gray glaze with the simple natural artistic effect of ancient pottery is still not seen in relevant reports and technical disclosures in my country at present by using plant ash to fire , and the patented technology of the present invention can effectively fill this gap
