Technical Field

The invention relates to the field of ceramic glaze, in particular to a ceramic glaze with metal texture and a preparation method and application thereof.

Background

The metal glaze is a special artistic glaze in glaze materials in the ceramic industry, and is mainly applied to archaized brick tiles, and also applied to bottles and cans, vases or artistic porcelain for daily furnishing porcelain. The surface of the ceramic tile with the metal glaze presents metallic luster, and can present various colors, such as red, yellow, silver, blue, black and the like. However, in order to obtain a glaze surface with better gloss, a lead-containing fritted glaze is generally used in the prior art, but a large amount of lead-containing fritted glaze not only brings great safety hazards to the health of production workers, but also brings potential hazards to the health and safety of consumers because the prepared ceramic product still contains lead, so that the development of a ceramic glaze material is needed, and the ceramic glaze material with better glaze surface gloss and metal texture can be obtained without adding the lead-containing fritted glaze, so that the requirement of practical production is met.
