Abstract
The invention provides a firing craft for Nixing pottery wall hangings. The firing craft comprises the following steps: (1) mixing 58-62 weight parts of soil in the eastern region of the Qinjiang river, 36-44 weight parts of soil in the western region of the Qinjiang river, 0.1-0.3 weight part of charcoal powder and 0.2-0.4 weight part of walnut shell powder till the mixture is uniform to obtain a blank; (2) manufacturing various shapes of soil plates by utilizing the blank; (3) drying the soil plates till the moisture of the soil plates is removed; (4) conducting carved decoration on the surfaces of the dried soil plates; (5) placing the decorated soil plates into a kiln for firing, wherein after the kiln is heated from room temperature to 200 DEG C within 1-1.5 hours, heated to 600 DEG C at a heating rate of 45-55 DEG C per hour, and heated to 1050-1100 DEG C at a heating rate of 65-75 DEG C per hour, heating is stopped for natural cooling, and then the Nixing pottery wall hangings are taken out of the kiln. Through the adoption of the firing craft, both the firing success rate and the glaze color change rate exceed 90%.
Description
Technical field
The present invention relates to the sintering technology of Nixing pottery, be specifically related to a kind of sintering technology of Nixing pottery wall hanging.
Background technology
Nixing pottery wall hanging is that (earth crossing Jiang Yidong is by the emperor himself soft clay with the distinctive eastern mud in Qinzhou Prefecture, color is yellow-white, containing micro-quartz sand, in the production technique of Nixing pottery, play adjustment plasticity-and associativity effect) and western mud (the by the emperor himself earth of region to the west of river, containing a small amount of K
2o, NaO, CaO, MgO, Fe
2o
3, TiO
2, MnO
2, be the purple mudstone that a kind of iron-holder is higher, color is red-purple, and upper layer has a small amount of irony to contaminate, and is flint clay, plasticity-and associativity poor) for raw material is through the ornament be suspended on wall of overmolding, drying, engraving and high-temperature firing.Because Nixing pottery wall hanging decorations are large-scale ornaments, its size more general Nixing pottery utensil (length >=0.8m, wide >=0.6m, thick >=5cm) bigger than normal, fire difficulty higher, very easily hardening crack, the rate of burning till is only 40 ~ 50%.Moreover, the transmutation rate of traditional wall hanging sintering technology is also lower, is only 20 ~ 30%.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of sintering technology burning till the Nixing pottery wall hanging that rate and transmutation rate significantly improve.
Technical scheme provided by the invention is the sintering technology of Nixing pottery wall hanging, comprises the following steps:
1) by eastern mud 58 ~ 62 weight part, western mud 36 ~ 44 weight part, wood charcoal powder 0.1 ~ 0.3 weight part and walnut shell flour 0.2 ~ 0.4 weight part, mixing, obtains blank;
2) blank is made the mud plate of different shape;
3) mud plate is carried out drying treatment, mud plate moisture is got rid of;
4) sculptured ornament is carried out on dried mud plate surface;
5) the mud plate decorated is sent into kiln to fire, from room temperature to 200 DEG C in 1 ~ 1.5 hour, 600 DEG C are risen to again with the speed of intensification per hour 45 ~ 55 DEG C, then 1050 ~ 1100 DEG C are risen to the speed of intensification per hour 65 ~ 75 DEG C, stop heating, naturally cooling, kiln discharge, is Nixing pottery wall hanging.
Above-mentioned steps 1) in, by eastern mud 60 weight part, western mud 39.7 weight part, wood charcoal powder 0.1 weight part and walnut shell flour 0.2 weight part, mixing, obtains blank.
Above-mentioned steps 1) in, the granularity of described walnut shell flour and charcoal is 200 ~ 500 orders.
Above-mentioned steps 5) in, the mud plate decorated is sent into kiln fire, from room temperature to 200 DEG C in 1 hour, 600 DEG C are risen to again with the speed of intensification per hour 50 DEG C, then rise to 1100 DEG C with the speed of intensification per hour 70 DEG C, stop heating, naturally cooling, kiln discharge, is Nixing pottery wall hanging.
The present invention compared with prior art, possesses following beneficial effect:
1) owing to being mixed with walnut shell flour and wood charcoal powder in blank, uniform pore (cavity) can be formed between eastern mud and western mud, can offset or cushion the violent contraction that mud plate produces in sintering procedure, thus prevent mud plate from hardening cracking, greatly improve and burn till rate.In addition, due to the existence of pore, the high temperature viscosity of mud plate can be reduced, reduce the discharge resistance of gas in sintering procedure, avoid mud plate to cause the needle pore defect on mud plate surface because gas cannot get rid of in time.
2) walnut shell flour and wood charcoal powder are mixed in mud intralamellar part, in sintering procedure, incomplete combustion can occur, produce a certain amount of reducing gas at mud intralamellar part, and then increase transmutation probability.
