Abstract

The invention discloses a preparation method for improving firing rate of Nixing pottery, comprising the steps: 1, preparing a preform made from 50-60 parts of Eastern clay, 30-40 parts of Western clay, 6-8 parts of quartz, 2-4 parts of wollastonite, 1-3 parts of illite, 1-3 parts of diopside, and 2-4 parts of calcined talcum powder; 2, performing forming; 3, performing dressing; 4, performing drying; 5, performing decorating; and 6, performing firing: a, firing a decorated preform in a kiln, heating the inside of the kiln to 70-80 DEG C at a temperature rise rate: 30-40 DEG C / h, and holding the temperature for 7-9 h; b, increasing the temperature to 100-120 DEG C at a rate: 40-50 DEG C / h, and holding the temperature or 1-3 h; c, increasing the temperature to 1120-1160 DEG C at a rate: 70-90 DEG C / h, and holding the temperature for 0.7-0.9 h. By modifying a firing process and changing composition of the preform, shrinkage rate and fission rate of the preform are decreased, and the firing rate is increased.

Description

technical field [0001] The invention relates to a preparation method capable of increasing the firing rate of Nixing pottery, belonging to the technical field of pottery manufacture. Background technique [0002] Nixing pottery, whose scientific name is purple clay pottery, is listed as the four famous pottery in China, together with Yixing purple sand pottery in Jiangsu, Jianshui pottery in Yunnan, and Rongchang pottery in Chongqing. The biggest feature of Nixing pottery is that it makes use of the occasional kiln changes during firing to make it appear in different colors, increasing its aesthetic value and practical value. Therefore, Nixing Pottery's "kiln transformation" art enjoys the reputation of "China's unique" in the domestic ceramic industry. The preparation process of Nixing pottery mainly includes the following steps: 1) Preparing blanks: mixing 40-60% of the east clay and 40-60% of the west clay (the east clay is mainly distributed in the area east of the Qinj...
