Preparation method for improving firing rate of Nixing pottery
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.
