Furnacetransmutation method for large Nixing pottery products
The invention provides a furnace transmutation method for large Nixing pottery products. The furnace transmutation method for large Nixing potteryproducts comprises the following steps: 1) preparation of blank material: using 55-65 parts by weight of east mud, 30-40 parts by weight of west mud and 5-10 parts by weight of iron ore powder to prepare the blank material; 2) shaping of blanks: making the blank material into various shapes of large vessels; 3) drying the blanks and 4) firing the blanks: loading the dried vessel blanks into a furnace and raising the temperaturegradually; specifically, raising the temperature to 500-750 DEG C at a speed of 30-50 DEG C/h, adding furnace transmutation material at 500-750 DEG C and sealing vent holes of the furnace; then, raising the temperature to 1000-1050 DEG C at a speed of 200-250 DEG C/h and firing at the constant temperature of 1000-1050 DEG C for 0.5-1h; naturally cooling and taking out of the furnace, thus obtaining finished large Nixing pottery products. The furnace transmutation method for large Nixing potteryproducts is capable of improving the furnace transmutation rate while ensuring the firing yield oflarge Nixing pottery products.
