Material name	Quartzy	Feldspar	Loess	Lime stone	Datong District's soil	Zinc oxide
							Proportioning %	21-22.5	30-32.5	30-32	10-13	4-4.8	1.5-2

Titanium fancy glaze prescription:

Material name	Quartzy	Record glass	Lime stone	The red lead	Titanium dioxide
						Proportioning %	13.5-14.5	41-43.3	13.5-14.3	12-14	14-16

It is at high temperature melt and dissolved that fancy glaze is actually two-layer glaze, flow into a kind of very natural magnificent color, that a kind of tone also depends on the composition of the metal oxide that adds in the cover-coat enamel, as a kind of whiting of desire system, the fancy glaze of yellow black tune, the prescription of its cover-coat enamel is to go up table, a kind of black glaze that contains cobalt, manganese that ground-coat enamel still makes with the basis of loess, and the prescription of black glaze:

Material name	Loess	Lime stone	Manganese oxide	Cobalt oxide
					Proportioning %	75-79	11-13	5-6	3-5

The present invention is owing to use unique production method, extension dish production efficiency is improved greatly, and image content can arbitraryly change, and increases, artistic effect is more rich and varied, makes sculptor and artist's intelligence and wisdom coil the performance that obtains in this world incisively and vividly at extension.Can make sculpture enter into huge numbers of families, embossment can be made great man's picture, the name portrait, and the religion idol, zoomorphism, the subject matter that sculpture can be done all can be made the subject matter of extension dish, and it is beautiful in ice, effect uniqueness to burn till after image.

(summary)

The specific embodiment

To produce celadon extension dish is example

At first, select materials based on Dongshan earthenware, require totally free from admixture, no mountain skin soil, no organic matter, ball milling sieves then, deironing, promptly make blank, plate is made with pulling wheel, and embossment is to use the mould manufacturing, after dish base and embossment base make, just can go into the kiln biscuiting, the biscuiting temperature is the 850-900 degree, can distinguish glazing, concentration of glaze slip specific gravity control 1.73 after biscuiting is good, the glaze layer thickness is controlled at 1.8 millimeters, blue or green glaze on the dish base, formulation by weight is: quartz: feldspar: loess: lime stone: Datong District's soil: zinc oxide=22: 32: 30: 11: 4.8: 0.2, titanium fancy glaze on the embossment base, the glaze weight proportion is: quartz: record glass: lime stone: red lead: titanium dioxide=14: 42: 14: 15: 15, with plate and embossment drying, recombinant is promptly gone into kiln and is burnt till at 1310-1320 degree high temperature to together then, plate glaze and embossment glaze at high temperature bond together naturally, burn till below the attention some: the 1. little fire stage.Heat up and want slow, allow the interior made-up article of kiln fully discharge moisture, unsuitable too fast, be approximately 300 degree.2. oxidation stage.The 300-1040 degree requires in the combustion chamber coal to grill thoroughly before each coal, stove fire is limpid.To changeing before fire is put is that the 1000-1040 degree carries out the moderate heat insulation, dwindles upper and lower temperature difference, lays a solid foundation for changing reduction over to.3. reduction phase, reducing flame is inadequate at air, under the inadequate situation of burning, a kind of flame of generation.Press how many strong reduction of branch again of content of CO, weak reduction, generally the oxidation stage from 1040 degree changes the reinforcement reduction over to, adds the smokestack pulling force after 6-8 hour gradually to change weak reduction gradually over to, until truce.Note the coal amount in making a fire, the combustion chamber remains girdle, must guard against grate and the hole occurs and advance cold wind and cause the product sootiness.4. last key is to cease fire; after having fallen, the pyrometric cone of 1310 degree also should be incubated 2-3 hour; to draw even kiln temperature, dwindle the temperature difference, and in conjunction with the fire handleless cup; the several aspects of perusal and experience are in conjunction with deciding the truce time; the back of ceasing fire slowly is cooled to naturally, prevents that product from bursting, at last kiln discharge just; pick has been packed.
