Problems solved by technology

[0005] However, if the traditional Linglong glaze is used on bone china, the residual air bubbles in the porous glass body of bone china Linglong products are difficult to eliminate, and opacification is easy to occur; and because the expansion coefficients of traditional Linglong glaze and bone china do not match, Poor thermal shock resistance during use, prone to crack defects

Embodiment 1

[0020] This embodiment discloses a bone china exquisite glaze, which includes the following components and parts by weight: 20.5 parts of quartz, 34 parts of potassium feldspar, 18 parts of borax, 11 parts of barium carbonate, 4.5 parts of strontium carbonate, lithium carbonate 2 parts, 2 parts of zinc oxide, 4.5 parts of aluminum hydroxide, 3 parts of talc, 0.5 part of zirconium silicate.

[0021] Take the above raw materials and stir them evenly, melt them into a frit at 1340°C, put the water-quenched frit into a ball mill, add water with a mass percentage of 26% based on the total mass, wet ball mill for 48 hours, and fineness million-hole sieve For the remaining 0.08%, add 0.1% xanthan gum and 0.3% sugar syrup, grind for 2 hours and pass through a 200-mesh sieve for later use; after the bone china body has been repaired, it is fired at 650°C, and the plastic film that has been hollowed out according to the design is pasted , use a sandblasting machine to sandblast and dril...

Embodiment 2

[0024] This embodiment discloses a bone china exquisite glaze, which includes the following components and parts by weight: 16 parts of quartz, 28 parts of potassium feldspar, 17 parts of borax, 6 parts of barium carbonate, 3 parts of strontium carbonate, lithium carbonate 4 parts, zinc oxide 6 parts, aluminum hydroxide 5 parts, talc 3 parts, zirconium silicate 1 part, calcite 12 parts.

[0025] Take the above raw materials and proportioning, weigh the required raw materials and stir them evenly, melt them into a frit at 1350°C, put the water-quenched frit into a ball mill, add water with a mass percentage of 28% based on the total mass, and wet Ball mill for 48 hours, fineness 0.05% of 10,000-hole sieve, add 0.1% xanthan gum, 0.3% sugar syrup, grind for 2 hours and pass through 250-mesh sieve for later use; after trimming the bone china body, biscuit at 750°C, Paste the plastic film that has been hollowed out according to the design, sandblast and drill holes with a sandblast...

Abstract

The invention relates to a bone-china exquisite glaze. The glaze comprises the following components in parts by weight: 16-24 parts of silica, 0-8 parts of clay, 28-38 parts of feldspar, 12-18 parts of borax, 0-7 parts of boric acid, 10-17 parts of barium carbonate, 0-5 parts of strontium carbonate, 0-8 parts of lithium carbonate, 2-12 parts of zinc oxide, 0-6 parts of aluminum hydroxide, 0-3 parts of talc, 0-12 parts of calcite and 0-1 part zirconium silicate. The glaze has the advantages of good transmittance and no opaque phenomenon and is exquisitely carved and glittering and translucent like jewels; the invention also provides a method for fabricating bone-china exquisite products from bone-china exquisite glaze, according to the method, residual bubbles can be eliminated, at the same time, the expansion coefficients of the glaze and the bone china are matched, quick heating and cooling resistance of products are improved and the cracking problem is avoided.

Description

technical field [0001] The invention relates to a bone china exquisite glaze and a method for making bone china exquisite products with the glaze. Background technique [0002] Linglong porcelain started from the end of the Northern Dynasties to the beginning of the Sui Dynasty. It was not seen in the Tang, Song, and Yuan Dynasties. In the Yongle period of the Ming Dynasty, Jingdezhen kilns produced sweet white glazed Linglong. After that, they reappeared in the Qianlong period of the Qing Dynasty, but the number was very small. As for the Yongle period Linglong porcelain is rarely handed down, and it is not easy to see. [0003] The production of Linglong porcelain stems from product defects. In Jingdezhen porcelain in the Song Dynasty, there was a product called smoked furnace. The furnace cover was decorated with hollows. During the firing process, due to the high temperature fluidity of the glaze and the poor control of the firing temperature, the temperature in the kil...
