Problems solved by technology

[0004] Bone china is good in decoration, which is an inherent characteristic that other porcelains cannot match. At present, high-grade bone china colored porcelain is made by the decoration method of pasting in-glaze colored flower paper on white bone china products. Melted into the glaze layer during the firing process; Chinese red and imperial yellow low-temperature colored glaze decorations have been widely used in bone china, and the decoration process is complex and diverse
Due to technical reasons, low-temperature matte glaze has low glaze hardness, poor stain resistance, poor acid and alkali corrosion resistance, etc., and matte glaze has not been used in the decoration of bone china products.

Abstract

The invention relates to bone matte glaze. The bone matte glaze comprises, by weight, 100 parts of frits, 3-8 parts of clay, 2-12 parts of aedelforsite, 3-6 parts of aluminum oxide, 6-15 parts of zinc oxide and 6 parts of stannic oxide. The frits comprise, by weight, 16-24 parts of quartz, 28-38 parts of potash feldspar, 12-18 parts of borax, 0-7 parts of boric acid, 0-5 parts of strontium carbonate, 0-8 parts of lithium carbonate, 0-10 parts of zinc oxide, 0-3 parts of talcum, 0-12 parts of calcite and 0-0.5 part of zirconium silicate. The glaze surface of a product using the glaze is fine, smooth, resistant to pollution, resistant to acid and alkali, easy to wash and suitable for the decoration means such as decal. The invention further provides a method for manufacturing the bone china product by using the bone matte glaze. The method is simple in firing process, stable in production and good in benefit.

Description

technical field [0001] The invention relates to a bone matt glaze and a method for making bone china products with the glaze. Background technique [0002] Bone china is called bone china for short, and its scientific name is bone china. It is a kind of porcelain made of animal bone carbon, clay, feldspar and quartz as the main raw materials, which are fired twice after high-temperature plain firing and low-temperature glaze firing. The national standard for bone china contains more than 30% tricalcium phosphate from animal bones, and the finished product has light transmission, so it can become bone china, while the American standard must reach at least 25%. [0003] Bone china has beautiful appearance, delicate and transparent porcelain, high regularity, elegant and beautiful shape, moist and bright glaze, strong decoration, colorful flower surface, high mechanical strength, good impact resistance, and can be made into thin tire products. Bone China was originally produ...
