A kind of in-glaze decoration method that is used for bright red glaze porcelain
Technical field
The invention belongs to the Ceramic glaze color-painting method, be specifically related to a kind of in-glaze decoration method that is used for bright red glaze porcelain.
Background technology
The glaze ceramic pigment of similar redness is too much planted in development on the Chinese history, as the iron oxide red of orange, mauve manganese red, bay copper red etc., and large red colorant truly has only modern artificial synthetic cadmium sulfoselenide (being called for short the selenium cadmium red) a kind of at present, and scientific research personnel and manufacturing enterprise do a lot of work around the application of selenium cadmium red on Production of Ceramics in recent years.
The selenium cadmium red is a kind of pink solid when synthetic, can become the large red glaze if be equipped with suitable parent glaze through firing more than 600 ℃, but its thermostability is bad, promptly begins more than 600 ℃ to decompose, and this has big gap with the glaze temperature that becomes more than 1000 ℃ of producing upward requirement usually.For many years production and scientific research personnel are being devoted to improve the thermostability of selenium cadmium red to make high-temperature red glaze, at present main use warm red glaze (about 1050 ℃ of firing temperature) and high temperature parcel red glaze in slow the decomposition arranged, it is exactly a kind of technology of comparative maturity that high temperature wraps up glaze.This technology is primarily aimed at the labile problem of selenium cadmium red,, and makes the high temperature scarlet glaze as colorant and achieves success improving its thermostability with the zirconium silicate crystal of high temperatures parcel selenium cadmium red.This glaze is not tight to firing the kiln furnitures requirement, and firing temperature reaches 1100 ℃-1300 ℃, but suitability for industrialized production, the smooth exquisiteness of glaze, because the glaze quality height, for good condition has been created in the art processing of carrying out the later stage, as roasting gold, colored drawing on the glaze.
Main at present for the surface working of red glaze product with the over-glaze decoration (or applique) and the two kinds of technologies of painting in gold.Can only use glass gold and low temperature colorant in baking below 600 ℃ with the red glaze that low temperature glaze is fired, the color of picture and adhere firmly degree are all undesirable, withdraw from the market gradually.Warm red glaze and the existing trailing of parcel red glaze glaze are generally colored drawing (applique), retouch, gild in slow the decomposition, burn till about 800 ℃, and rich color adheres to comparatively firm.But owing to be over-glaze decoration, shortcoming such as it is not wear-resisting to exist picture, and the objectionable impurities stripping quantity is big, application is restricted.
In-glaze decoration is a kind of new decoration of porcelain material and the skill and technique that the seventies grows up.Also claim high temperature rapid firing stains.The flux component of pigment is not leaded or few leaded, imposes on the implements glaze by the over-glaze decoration method, and by 1100 ℃-1260 ℃ high temperature sintering, glaze softens fusion, and pigment is infiltrated in the glaze layer, cooling back glaze face closure.Exquisiteness is jade-like stone, moist order all of a sudden carefully, and is anticorrosive, wear-resistant, has the effect of under glazed.And solved the stripping problem of ceramic picture lead.Past in-glaze decoration technology mainly is to be applied in white glaze, the report of also not using on the large red glaze at present.
Make difficult point for bright red overglaze in-glaze decoration two aspects arranged:
The one owing to contain active sulphur, selenium under the high temperature in the red glaze, the high-temperature zone more than 1000 ℃ easily with glaze on other colorant generation chemical reactions of infiltering, the color that can not get expecting also can make defectives such as glaze generation wrinkle, pore under many circumstances.
The 2nd, physical factor because bright red glaze belongs to color glaze, will inevitably produce to a certain degree mixing and covering mutually after other colorants sink to wherein, cause the color development skew.
Therefore will burn out red glaze prizes and must solve following three problems.
1, stop sulphur, selenium in the glazed layer free, to avoid the reaction of itself and in-glaze decoration colorant the high-temperature zone.
2, the in-glaze decoration colorant is screened, observe the quality situation of various colorants after red glaze infiltration.
3, on the basis that solves above two problems, carry out the relation of various coloring material for mixing color developments and firing temperature, time and depth of penetration again.
Summary of the invention
The object of the present invention is to provide a kind of in-glaze decoration method that is used for bright red glaze porcelain.The porcelain surfacing of adopting this method to make is smooth, and wear resistance is good, and lead release is few.
The objective of the invention is to be achieved through the following technical solutions:
A kind of in-glaze decoration method that is used for bright red glaze porcelain may further comprise the steps:
1) take one of the plum vase that the parcel red glaze through 1100-1300 ℃ of high-temperature firing burns till, remove degreasing, dust with the washing composition clean surface, stand-by after 105 ℃ of oven dry;
2) used ceramic pigment powder is determined through observing the quality situation after red glaze infiltration:
