Problems solved by technology

[0003] 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 being made into frits, the precipitation of harmful substances is inevitable, and the use of them on Nixing pottery is contrary to the product concept of Nixing pottery's health and environmental protection; some frits The coverage 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 discloses a matt light brown raw material glaze specially used for Nixing pottery. Composed of calcium borate, the glaze achieves a matte light brown color effect after firing, has strong adhesion to the Nixing pottery body, and has extremely low content of lead compounds and cadmium compounds, which is consistent with the environmental protection of Nixing pottery as a green product. The concepts match. The invention also discloses a preparation method of matt light brown raw material glaze special for Nixing pottery, including weighing the raw material, ball milling, detecting fineness, sieving, and stale for use. The preparation method of the invention is simple and easy for large-scale production.

Description

technical field [0001] The invention relates to a ceramic glaze, in particular to a Nixing pottery glaze and a preparation method thereof. Background technique [0002] Nixing pottery belongs to fine pottery with high iron content, and the color of its body is generally iron red. The iron element in the body of this kind of pottery itself is already a colorant, and its inherent color has a strong influence on other colorants. Colorants are not easy to cover. [0003] 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 being made into frits, the precipitation of harmful substances is inevitable, and the use of them on Nixing pottery is contrary to the product conc...
