Description

A kind of burning process of under-glaze red porcelain
Technical field
The present invention relates to porcelain burning techniques fields, and in particular to a kind of burning process of under-glaze red porcelain.
Background technology
Under-glaze red porcelain is that a kind of color under glaze in high temp paints porcelain, since this red requirement to firing environment and temperature is omited Be worse than it is blue and white, so successfully under-glaze red porcelain be phoenix feathers and unicorn horns.According to the creativity and innovation of biography under-glaze red porcelain also because of primary Accidental coincidence says to be Yuan Dynasty coppersmith round the apron for being stained with copper scale, when looking for the skill craftsman chat for drawing porcelain to kiln factory, copper scale Shake off on the not dry base face of molding porcelain, because copper scale powder particle is subtle, it is difficult to visually observe to obtain, so when dipping in glaze water Also do not found and handled by craftsman, after while enter kiln through 1350 degree high-temperature firing blue and white porcelain, glued copper scale vessel position and also Primordial Qi atmosphere is fired into scattered red of swooning, fortunately this copper to be reduced into red temperature requirement almost with it is blue and white Unanimously, through investigating, caused by finding the copper scale on this red as coppersmith's apron, like this, a kind of new product of underglaze colour porcelain Kind-" under-glaze red " appearance like this.Xuande period is arrived, under-glaze red porcelain has come into the maturity period, it thoroughly breaks away from First that dark red, pink dark and gloomy tone of end.It grasps preferably moreover, Xuande period makes technology to the burning of rough flambe, is referred to as " ruby red ".Xuande under-glaze red is handed down from ancient times few, and pure white carcass is matched with bright and beautiful under-glaze red, has reached under-glaze red technique Rise to more graceful boundary.At present since blank is different from colored glaze material property, be susceptible to under-glaze red colorant it is crimson, black And blue and white colorant colour generation is uneven, or even glaze generate pin hole can bubble, it is serious to reduce porcelain quality.
Invention content
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of burning process of under-glaze red porcelain, in the glaze fired Red porcelain carcass is fine and smooth, decorative pattern is clear, and color and luster is popular in gorgeous, has high ornamental and reserve value.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of burning process of under-glaze red porcelain, includes the following steps：
(1) blank, colored glaze material are prepared：
The blank is made of the raw material of following parts by weight：SiO2 100-150、Al2O3 50-70、CaO 20-40、 K2O 10-30、FeO 8-15、Na2O 1-6、Na2CO310-20, MgO5-15, black earth 2-10；
The colored glaze material is made of the raw material of following parts by weight：SiO2 80-120、Al2O3 20-45、CuO 5-9、K2O 3-8、Sr O 2-10、ZnO 5-10、SnO21.5-3.5、SiC 1-1.8；
(2) by blank grinding and sieving, except iron, pugging, aging, refining, mud is added water into, then mud is poured into mold In be pressed into porcelain body, porcelain body is placed in 8-12 DEG C of storehouse and is dried in the shade naturally, polished after drying in the shade and carry out biscuiting again three times；
(3) porcelain body is carried out to biscuiting at 950-1050 DEG C, the biscuiting residence time is 20-40min；
(4) it is first finally dried with covering upper clear frit again after colored glaze material glazing；
(5) porcelain body after glazing is placed in pushed bat kiln and is fired by glaze with oxidizing flame, temperature of glaze firing is 1200-1250 at the beginning DEG C, after being fired by glaze 30-40min, it is warming up to 1300-1360 DEG C, after being fired by glaze 4-6h, with the greenhouse cooling kiln discharge of 40-50 DEG C/min, i.e., Finished product can be obtained.
Preferably, blank crushes the sieve for crossing 80 mesh, 200 mesh and 400 mesh three times and respectively in step (2).
Preferably, the time aging in step (2) is 10-15d.
Preferably, the vacuum degree in step (2) when refining is 0.1-0.2MPa.
Preferably, the humidity of storehouse is 30-50% in step (2).
Preferably, drying temperature is 80-100 DEG C after glazing in step (4).
(3) advantageous effect
The present invention provides a kind of burning process of under-glaze red porcelain, have the advantages that：
A certain amount of SiC is added in colored glaze material as reducing agent, is fired by glaze with oxidizing flame, does not have to additional control also Former atmosphere, glaze firing process are easier to control, and the scarlet stabilization of glaze colours being burnt into；It is fired by glaze using two sections of heatings, phase It is preheated when in glaze layer, avoids being warming up to 1250 DEG C or more suddenly, copper coin biscuiting is caused to lose, occurring swooning dissipates, is crimson, favorably In improving yield rate, using under-glaze red porcelain colour generation stable and uniform made from present invention process, gorgeous, without crimson, do not black, have There is high ornamental and reserve value.
