Abstract

The invention discloses a copper red glaze and a preparation method of the copper red glaze. The copper red glaze is prepared from the following raw materials in parts by weight: 5 to 9 parts of kaolin, 15 to 20 parts of rice husk ash, 18 to 22 parts of wollastonite, 35 to 45 parts of a glazed fruit, 1 to 2 parts of talc, 0.5 to 1 part of added copper oxide, 1 to 2 parts of bovine bone ash and 2 to 4 parts of tin oxide; the preparation method of the copper red glaze comprises the following steps: preparing materials, carrying out ball milling, rotting, dipping the glaze, drying, firing and forming porcelain and a finished product. The preparation method of the copper red glaze disclosed by the invention has the beneficial effects of using the wollastonite to replace lime-fly ash and the rice husk ash containing a certain amount of unburned carbon and capable of being used as a high-temperature reducing agent to replace quartz; compared with the lime-fly ash, the wollastonite is stablein content of calcium, higher in mature temperature and not decomposed, thereby being beneficial to avoiding generation of pinholes and the like, and the talc is added to prevent the glaze from absorbing smoke during the firing process, and therefore, the glaze is more stable in color and good in product appearance.

Description

technical field [0001] The invention relates to the technical field of preparation of ceramic materials, in particular to a copper red glaze and a preparation method thereof. Background technique [0002] Copper red glaze is a red glaze fired with copper-containing substances as a colorant by reducing flames. According to archaeological data, the Tang Dynasty in my country has begun to use copper to burn red. In the Song Dynasty, Jun Kiln in Yuxian County, Henan Province had already fired a large number of copper-red spot Jun glaze porcelains; Xuande's bright red (also known as "Ji Hong", "Ji Hong") is the most famous. Copper red glaze was once lost in the mid-Ming Dynasty, and it was restored in the Kangxi Dynasty of Qing Dynasty, and it was fired into Langyaohong, cowpea red and other precious varieties. Since ancient times, this kind of bright red firing has been extremely rare and has been treasured by the world. The coloring of copper in glaze is not only related to t...
