Ceramic jade white glaze and glaze application method

Abstract

The invention discloses ceramic jade white glaze. The comprises the following ingredients, by weight, 48-52 parts of albite, 5-8 parts of calcium carbonate, 7-9 parts of kaolin, 33-36 parts of quartz, 5-7 parts of barium carbonate, 0.4-0.6 part of calcium borate, 1-3 parts of strontium carbonate, 0.5-1.5 parts of bentonite and 0.01-0.02 part of methyl cellulose. Glazing modes comprise glaze soaking and glaze spraying twice. The sintering curve comprises four stages of 1 DEG C-300 DEG C, 300 DEG C-600 DEG C, 600 DEG C -1000 DEG C and 600 DEG C-1330 DEG C. The ceramic jade white glaze has a low cost and a wide adaptability, the saying is changed that Dehua ceramic whiteware only depends on good porcelain clay in history, a ceramic product made from the provided ceramic jade white glaze and through the glaze application method is oily and fleshy like Hetian jade and is ivory, and a layer of brightness appears on the glaze surface. Especially, when thickening is carried out during glaze application of a green body especially, the glaze flows vertically when high temperature sintering and when the glaze fluid flows and deposits, the Hetian jade texture is strong and the lightspot is shown.

Description

technical field [0001] The invention relates to the fields of daily-use ceramics and technical ceramics, in particular to a ceramic jade white glaze and a glaze application method thereof. Background technique [0002] China white porcelain, referred to as "China white", has a long history in China. The discovery of white porcelain in the Northern Wei Dynasty brought the earliest appearance of white porcelain from the Northern Qi Dynasty to the Northern Wei Dynasty, rewriting the history of Chinese ceramics. Ivory white is White porcelain with pure transparent glaze from the Dehua Kiln of the Ming Dynasty. Because the content of ferric oxide in the glaze is very low, but the content of potassium oxide is not particularly high, and the neutral atmosphere is used for firing, so the color is very pure. From the appearance, the color is smooth and bright; under the light, pink or milky white appears in the glaze, so it is called lard white and ivory white. Europeans also call ...

AI Technical Summary

Problems solved by technology

[0006] (3) From the perspective of the transparency of the combination of porcelain and glaze, Dehua white porcelain has been said to be "thin body and thin glaze" since ancient times. In addition, the transparency of Dehua porcelain clay is good, making it particularly crystal clear, but the glaze color is not Thick feeling, not oily enough, not attractive enough

[0007] However, Dehua's "China White" has always relied on the quality of selected porcelain clay to develop its color from ancient times to the present. Therefore, there is no way for Dehua white porcelain to talk about changes in glaze art with other kilns, only to talk about the quality of porcelain clay.
