Problems solved by technology

[0004] Among the existing porcelain glazes, the glazes suitable for the firing temperature of pottery are generally low-temperature frit glazes. Due to the low firing temperature, most of the frits used contain some toxic compounds, such as lead compounds and cadmium compounds. etc. Although the toxins of these compounds are effectively controlled to a certain extent after they are made into frits, the precipitation of harmful substances is unavoidable, and the use of them on Nixing pottery is contrary to the product concept of Nixing pottery's health and environmental protection; in addition, some The coverage of the frit is not strong enough to completely cover the inherent iron red of Nixing pottery with high iron content, so some colors are poor in color rendering, such as blue series, green series, etc.
Moreover, the glaze layer of this kind of glaze is relatively thick, and the glaze layer is bright and smooth, which covers the unique surface effect of pottery and cannot highlight the beauty of pottery texture.

Abstract

The invention relates to the technical field of raw glaze, in particular to a glossy grass-green raw glaze special for Nixing pottery and a preparation method thereof. The lustrous grass green raw material glaze for Nixing pottery is composed of raw materials such as zirconium silicate, cerium oxide, calcium borate, calcite, feldspar, zinc oxide, veloci, quartz, apple green material, and malachite green material; the preparation method of the present invention The method includes weighing raw materials, ball milling, detecting fineness, sieving, and stale for use. The present invention is non-toxic and harmless in raw materials, which is consistent with the environmental protection concept of Nixing pottery as a green product, and completely abandons the non-environmental protection link of waxing, and has the decorative color effect of glaze; the preparation method of the present invention is simple, easy to Large-scale production.

Description

technical field [0001] The invention relates to the technical field, in particular to a special lustrous grass-green raw material glaze for Nixing pottery and a preparation method thereof. Background technique [0002] The glaze of ceramics is obtained through various physical and chemical reactions under the action of fire. It is a glassy substance formed by complex physical and chemical reactions of various mineral raw materials and inorganic chemical materials under high temperature conditions. The enamel imparts a non-porous waterproof coating to the final product, an aesthetic finish (glossy, matte, satin, etc.), color (background), opaque uniform interface on a clay support by screen printing, decoration itself (by silk Screen printing design) and effects (brilliance, metallization) and wear resistance of surface decoration, etc. [0003] Nixing pottery belongs to fine pottery with high iron content, and the color of its body is generally iron red. The iron element in...
