Abstract
The invention discloses a method for preparing underglaze bone china, which comprises the following production steps: preparing a bone china material into a blank; performing high temperature biscuit firing on the blank, wherein the temperature of the biscuit firing is between 1,250 and 1,280 DEG C; performing color painting on a product after the biscuit firing, wherein the pigment used by the color painting is prepared from the following compositions by weight percentage: 65 to 75 percent of colorradical and 25 to 35 percent of glaze; performing high temperature color firing on the product after the color painting, and the temperature of the color firing is between 1,200 and 1,250 DEG C; and glazing the product after the high temperature color firing with the same glaze in the pigment, and performing medium temperature glaze firing to prepare a finished product, wherein the temperature of the glaze firing is between 1,050 and 1,150 DEG C. The underglaze bone china prepared by the method has clear color painting patterns, strong stereovision, and rich, fresh and bright color of the color painting patterns, smooth, neat and delicate glaze and high firing rate.
Description
Technical field
The present invention relates to the working method of pottery, specifically is preparing underglaze bone china.
Background technology
The sclerotin porcelain is universally acknowledged high-grade porcelain kind.The sclerotin porcelain is creamy white, and is translucent, and product is extremely slim and graceful, and the glaze bright and clean is lubricated, and device shape regularity is very good, and entire body has no flaw, and lines are accurately attractive in appearance, the bright-coloured gracefulness of picture.It is main production traditional technology with the onglazed that present sclerotin porcelain mainly adopts decoration, and underglaze bone china is because the burning techniques more complicated is difficult to burn out the underglaze bone china that has good quality.
The Chinese patent publication number is CN101121601A, and open day is on February 13rd, 2008, and the name of innovation and creation is called sclerotin ceramic under-glaze decoration technique, and this application discloses a kind of sclerotin ceramic under-glaze decoration technique.The technology of this application discloses through adding glaze biscuiting (700～750 ℃), high warm colour burning (1180～1250 ℃) and medium temperature glaze burns the method that (1100～1180 ℃) three firing process are processed the sclerotin ceramic under-glaze decoration product.This technology is made the sclerotin porcelain through on plain embryo, executing starved glaze, is similar to in-glaze decoration and paints technology, and can form the glaze layer after adding the glaze biscuiting, and be unfavorable for drawing, and the clear patterns degree of its product is undesirable, and the colored drawing pattern gradation sense is not strong.
Summary of the invention
The invention provides the preparing underglaze bone china of strong, bright in luster bright, the smooth exquisiteness of glaze of a kind of clear patterns, gradation sense.
Preparing underglaze bone china of the present invention comprises following production stage:
(1), processes base substrate with the sclerotin ceramic material;
(2), above-mentioned base substrate is carried out the high temperature biscuiting, the biscuiting temperature is 1250～1280 ℃;
(3), on the product after the biscuiting, carry out colored drawing, the used colorant of colored drawing is processed by following component by weight percentage: color base (being shades of colour) 65～75%, glaze 25～35%;
(4), the product behind the colored drawing carried out high warm colour burn, it is 1200～1250 ℃ that look burns temperature;
(5), carry out the medium temperature glaze burning after the same glaze glazing in above-mentioned colorant on the product after high warm colour burns, temperature of glaze firing is 1050～1150 ℃, makes finished product.
Colorant described in the step (3) is preferably processed by color base 70%, glaze 30% by weight percentage.
The present invention at first carries out the high temperature biscuiting to base substrate through adopting three firing process, after the product that burns till is carried out colored drawing with colorant, carries out high warm colour again and burns, and makes colorant carry out physical and chemical reaction, is completely fixed; At last the product after the glazing is carried out medium temperature glaze and burn, make finished product.This firing process makes base substrate complete in the biscuiting post shrinkage owing to when biscuiting, adopt high temperature to burn till, and when look burns, adopts same high temperature to burn till, and has guaranteed that the shrinking percentage when base substrate carries out the look burning with colorant is consistent, and paint-coated pattern is clear, bright in look burning back; And be direct biscuiting, need not add glaze, both provided cost savings like this, also be convenient to the colored drawing of colorant, be pure under glazed; In colorant, add the used glaze of glazing, the sintering of colorant and glaze when being convenient to glaze firing, the sintering effect of glaze layer is good.
The colored drawing pattern of the underglaze bone china that the present invention processes is clear, gradation sense is strong, color is abundant and bright in luster bright, glaze smooth, exquisiteness, the rate of the burning till height of product.
Embodiment
Below through embodiment the present invention is carried out detailed explanation.
Process base substrate with the sclerotin ceramic material; Above-mentioned base substrate is carried out the high temperature biscuiting, and the biscuiting temperature is 1260 ℃; On the product after the biscuiting, carry out colored drawing, the used colorant of colored drawing is processed by 70% color base and 30% glaze by weight percentage; Product behind the colored drawing is carried out high warm colour burn, it is 1220 ℃ that look burns temperature; Carry out the medium temperature glaze burning after with above-mentioned same glaze glazing on the product after high warm colour burns, temperature of glaze firing is 1100 ℃, makes sclerotin porcelain finished product.
Claims (2)
1. a preparing underglaze bone china is characterized in that, comprises following production stage:
(1), processes base substrate with the sclerotin ceramic material;
(2), above-mentioned base substrate is carried out the high temperature biscuiting, the biscuiting temperature is 1250～1280 ℃;
(3), on the product after the biscuiting, carry out colored drawing, the used colorant of colored drawing is processed by following component by weight percentage: color base 65～75%, glaze 25～35%;
(4), the product behind the colored drawing carried out high warm colour burn, it is 1200～1250 ℃ that look burns temperature;
(5), carry out the medium temperature glaze burning after the same glaze glazing in above-mentioned colorant on the product after high warm colour burns, temperature of glaze firing is 1050～1150 ℃, makes finished product.
2. according to the said preparing underglaze bone china of claim 1, it is characterized in that colorant described in the step (3) is processed by color base 70%, glaze 30% by weight percentage.
