A special transparent raw material glaze for Nixing pottery

Abstract

The invention discloses transparent raw glaze special for nixing pottery. The raw glaze is formed by calcium borate, quartz, feldspar, limestone, florisil, talc and nixing argil through the steps of mixing, water adding for ball milling, sieving and decaying. After being sintered, the glaze is transparent in texture, and large in adhesion force to a nixing pottery blank, the content of lead compounds and cadmium compounds is extremely low, the pottery feature of the nixing pottery and the protecting function of the glaze are retained in the decorating effect, and practicality and the decoration property are organically combined.

Description

technical field [0001] The invention relates to a ceramic glaze, in particular to a glaze of Nixing pottery. 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 concept of Nixing pottery's health...

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.
