Abstract

The invention discloses a preparation method for reducing the firing temperature of Nixing ceramics. A blank is prepared from the following raw materials in parts by weight: 45 to 55 parts of east clay, 25 to 35 parts of west clay, 1 to 2 parts of bentonite, 1 to 3 parts of wollastonite, 0.1 to 0.3 parts of tremolite, 0.2 to 0.4 parts of powder quartz and 1 to 3 parts of aluminum oxide. The preparation method comprises the following steps: (a) heating to 70 to 90 DEG C at the speed of 25 to 35 DEG C / h, and keeping the temperature for 6 to 8 hours; (b) heating to 120 to 150 DEG C at the speed of 35 to 45 DEG C / h, and keeping the temperature for 2 to 4 hours; (c) heating to 400 to 500 DEG C at the speed of 60 to 80 DEG C / h, and keeping the temperature for 0.2 to 0.4 hours; (d) heating to 700 to 800 DEG C at the speed of 60 to 80 DEG C / h, and keeping the temperature for 0.1 to 0.3 hours; (e) heating to 1,040 to 1,060 DEG C at the speed of 80 to 100 DEG C / h, and keeping the temperature for 0.6 to 0.8 hours.

Description

technical field [0001] The invention relates to a preparation method for reducing the firing temperature of Nixing pottery, belonging to the technical field of pottery manufacture. Background technique [0002] Nixing pottery, scientific name Zini pottery, is a pottery with a long history and Qinzhou characteristics. It is also known as the four famous pottery in China together with Yixing pottery in Jiangsu, Jianshui pottery in Yunnan, and Rongchang pottery in Sichuan. The biggest feature of Nixing pottery in Qinzhou is its non-glazed finish. The burnt and polished pottery presents an endless variety of "kiln-changing" colors. The artistic taste is extremely high, and it is known as "a must in China". [0003] Although Nixing pottery is well-known overseas, its development is slow compared to the development of my country's pottery industry. This is because Nixing pottery is mainly based on ornamental and collection value to expand the market, and it is difficult to form a ...
