Embodiment Construction

[0040]A multicolored decoration method for underglaze bone china, which is characterized in that the method includes raw material preparation, hand-painted or pad-printed patterns, and three or four times of firing; the raw material preparation includes protective layer solvent powder, medium-temperature pigments, and tea leaves for hand-painting Preparation of water temperature pigment aqueous solution, pasty pad printing protective layer glaze material, surface layer frit glaze and foot special glaze, the specific steps are as follows:

[0041] The raw material preparation

[0042] (1) For the preparation of the protective layer solvent powder, prepare the materials according to the following formula ratio (weight ratio):

[0043] Longyan kaolin 9%, Guangxi cooked talc 7%, potassium feldspar powder 30%,

[0044] Albite powder 45%, quartz 9%,

[0045] Wet ball milling for 35 hours, selected material: ball: water=1:1.6:0.4; pass through a 325 mesh sieve after ball milling, t...

Abstract

The invention relates to an under-glaze colored decoration method of bone china. The method includes an under-glaze colored decoration firing process and a pigment preparation technology, which includes transferring figures through pigment paint or labels for porcelain to a biscuit after lower temperature biscuit firing at a temperature of 700-800 DEG C, covering a protective layer, buckling a decorated ware on a profiling kiln furniture, performing firing at a temperature of 1250-1290 DEG C, wherein figure surfaces cannot be bruised, performing polishing on figure bases after firing, spraying fritted glaze slip, and performing glaze firing at a temperature of 1170-1200 DEG C. The figure surfaces are arranged under a glaze layer completely, and the method is a novel color decoration different from bone china over-glaze color figure for in-glaze decoration. Blanks are performed biscuit firing at a low temperature, the figure bases are fired through oxidizing flames at a high temperature (1250-1290 DEG C), and vitreous enamels are fired through oxidizing flames at an intermediate temperature (1170-1200 DEG C). Compared with once-firing of under-glaze color figure through reducing flames at a high temperature, the method is a firing method in which the temperature and the flame property are completely different. Bottoms of high range gift porcelain products are glazed through lowtemperature glazes, and smooth and non-discoloring forever after firing at a temperature of about 800-850 DEG C.

Description

technical field [0001] The invention relates to a method for underglaze multicolored decoration of bone china, which is a new method for decoration of bone china in ceramic products, and relates to a new type of porcelain for underglaze multicolored decoration of ceramic products. Background technique [0002] Bone china is recognized as a high-grade porcelain and ceramic treasure in the world. China developed and produced bone china in 1973. The decoration of bone china painting has always been dominated by overglaze decoration. In recent decades, the inglaze decoration technology developed by foreign countries has added a second new method to bone china painting, which has been quickly promoted and is widely accepted. Consumers welcome. However, in-glaze color cannot be hand-painted, but a method of transferring patterns to white glazed porcelain, and after firing at about 1050-1100°C, the flower surface will dissolve into the glaze. The world-famous Liling underglaze ...
