Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of existing crystal glazes that have high requirements on firing conditions, require long firing time and holding time, and cannot be used for daily-use ceramics, and provide a firing system that is comparable to ordinary high-temperature reduction in large-scale production. The product is the same, no special kiln is required for firing, and it is suitable for large-scale production. At the same time, its thermal stability, lead and cadmium dissolution and other physical and chemical properties meet the relevant standards of national daily-use ceramics.

Abstract

The invention discloses high-temperature crystalline glaze. The high-temperature crystalline glaze is prepared from the following components in percentage by weight: 7-10% of spodumene, 45-48% of wollastonite powder, 4-5% of Guizhou clay, 6.5-10% of quartz powder, 4-6% of Longyan clay, 28-30% of barium carbonate and 0.5-1% of a toner. The glaze mainly contains the wollastonite and the barium carbonate, the wollastonite is supersaturated in the glaze to generate crystallization so as to generate wollastonite crystals, the excessive barium carbonate is introduced to form wollastonite-barium carbonate composite crystals, the crystals are uniform, fine and smooth and are spread on the surface of a glaze layer, so that the effect that the crystals float on the transparent glaze layer is achieved, the heat stability of obtained crystalline glaze products reach the national domestic ceramic standard, the lead-cadmium release reaches the national domestic ceramic standard, and auxiliary products can be stably produced in a large scale; and a product firing system, as large-scale production of the ordinary products, has no special requirements, the products do not need to be fired by a specific kiln, and the high-temperature crystalline glaze is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, and in particular relates to a high-temperature crystalline glaze and a preparation method thereof. Background technique [0002] Crystalline glaze is a kind of artificial crystal flower glaze developed on the basis of ancient glaze in my country. It is characterized in that crystal flowers of various shapes are precipitated in the glaze or on the surface of the glaze. These crystal flowers are made of crystal-forming substances in the glaze melt. In the supersaturated state, it is formed naturally by cooling and proper heat preservation. But existing crystalline glaze is a kind of high-grade ceramic art glaze, gives the person with strong artistic effect, is mainly used in making artistic pottery such as vase. At present, in the field of daily-use ceramics, the application of crystalline glaze is not very extensive. The main reason is that the crystalline glaze made of existing raw materi...
