Abstract

The invention discloses a novel sand crystal glaze utilizing mica iron oxide and a preparation process of the sand crystal glaze. The sand crystal glaze contains the mica iron oxide and a sand crystal base glaze. The novel sand crystal glaze utilizing the mica iron oxide can be prepared with fewer raw materials, and the raw materials adopted are rich in resource and low in price; by breaking through the traditional complex firing process of the sand crystal glaze and not requiring a special firing system, the preparation method is high in operability, relatively low in glaze production cost, and advantageous for energy conservation and environmental protection. The novel sand crystal glaze is simple to use; the sand crystal glazes different in color and effect can be fired by adjusting the formula of the glaze material; and rich and diversified colors enable the sand crystal glaze to take the lead in the building and sanitary ceramic industry and to be very popular with customers.

Description

technical field [0001] The invention belongs to the technical field of ceramics, in particular to a novel sand crystal glaze utilizing mica iron oxide and a preparation process thereof. Background technique [0002] Sand crystal glaze is a highly decorative artistic glaze. It enjoys a wide reputation for its unique artistic style and is quite popular among consumers. Sand crystal glaze originated from ancient black glaze. The color of black glaze is mainly because it contains a large amount of iron oxide and the glaze layer is thick, and most mineral raw materials contain a large amount of iron. This is why black glaze was invented as early as the late Han Dynasty. reasons that have arisen. From the Eastern Han Dynasty to the Sui and Tang Dynasties, the porcelain making process continued to develop, and coal was used as a new energy source in the Song Dynasty. At this time, the branch ring refiring technology was invented, and various technological innovations were required...
