Abstract

The invention discloses an antique matte glaze with delicate texture. The antique matte glaze with the delicate texture consists of a frit and raw materials, wherein the mass ratio of the frit to the raw materials is 1-1.5: 1. The invention also discloses a preparation method of the antique matte glaze with the delicate texture. The preparation method comprises the following steps of: applying a layer of base glaze on the surface of a brick blank, and applying a layer of the matte glaze; and sintering the brick blank at the temperature of 1150-1250 degrees centigrade to obtain a final product. The matte glaze provided by the invention consists of the frit with good high temperature fluidity and part of the raw materials, so that the glaze surface can flow levelly at high temperature quickly; through matching of different materials, the matte, smooth and delicate effects of the glaze surface are ensured; through the composition design of half raw material and half frit, the compositionis more stable and is applicable to different technical conditions and furnace temperatures; and the sintering temperature and the matte degree of the matte glaze are regulated by regulating the adding amount of aluminum oxide.

Description

technical field [0001] The invention relates to an antique matte glaze with delicate texture and a using 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. [0003] Matte glaze is a microcrystalline glaze of the matte glaze system, which is induced by very fine-grained crystals produced during the firing cycle. As a result of the crystallization, the glaze surface has a matte appearance. Adding elements that can cause a matte effect, in a certain firing temperature and a proper cooling rate, countless tiny single crystals are generated, and these countless tiny single crystals refract light, thereby producing a matte effect. Matte glaze is a high-grade decorative glaze for modern ceramics. It is the ...
