Method for increasing kiln transformation ratio of Nixing pottery large vessels
The invention provides a method for increasing kiln transformation ratio of Nixing pottery large vessels. The method comprises the following steps: 1) preparing blanks, namely producing the blanks from 50-60 parts by weight of east mud, 30-40 parts by weight of west mud and 8-15 parts by weight of iron oxide red; 2) blank forming, namely forming the blanks into various large vessels of different shapes; 3) shaping the blanks; 4) drying the blanks; and 5) firing the blanks, namely gradually increasing the temperature to the range of 500-750 DEG C at a temperature rise rate of 30-50 DEG C per hour, adding a kiln transformation material at the temperature and sealing the air holes of the kiln, and then increasing the temperature to the range of 1000-1050 DEG C at a temperature rise rate of 200-250 DEG C per hour, preserving heat at the temperature and firing for 0.5-1 hour, naturally cooling and taking out of the kiln, thereby obtaining the finished products large Nixing pottery vessels.
