Embodiment 1
[0028] The raw matte glaze described in Example 1 is prepared from the following raw materials by weight percentage:
[0029] Feldspar 64.0%, alumina 4.5%, zinc oxide 8.0%, limestone 14.0%, calcined talc 1.5%, titanium dioxide 1.0%, zirconium silicate 1.5%, barium carbonate 1.5%, and Suzhou soil 4.0%.
[0030] Firstly, various raw materials are weighed according to the above-mentioned ratio; secondly, they are added into a ball mill at the ratio of batch material: ball stone: water=1:2:1, and then 0.05% of the dispersant CMC is added to make a glaze slurry. The size of the glaze slurry is controlled to be less than 10 μm. The particles with a particle size of 80 to 87% are made into a slurry that is aged for 48 hours for use.
[0031] The prepared glaze slurry is applied to the unfired bone china greenware and fired at a temperature of 1120-1150°C to obtain a high-quality matte bone china product. The porcelain surface of the product is as polished as wax, and it has a smooth, delic...
Embodiment 2
[0033] The raw matte glaze described in Example 2 is prepared from the following raw materials by weight percentage:
[0034] Feldspar 64.5%, alumina 4.0%, zinc oxide 9.0%, limestone 14.0%, calcined talc 1.0%, titanium dioxide 1.0%, zirconium silicate 1.0%, barium carbonate 1.0%, and Suzhou soil 4.5%.
[0035] Firstly, various raw materials are weighed according to the above-mentioned ratio; secondly, they are added into a ball mill at the ratio of batch material: ball stone: water=1:2:1, and then 0.05% of the dispersant CMC is added to make a glaze slurry. The size of the glaze slurry is controlled to be less than 10 μm. The particles with a particle size of 80 to 87% are made into a slurry that is aged for 48 hours for use.
[0036] The prepared glaze slurry is applied to the unfired bone china greenware and fired at a temperature of 1130-1170°C to obtain a high-quality matte bone china product. The porcelain surface of the product is as polished as wax, and it has a smooth, delic...
Embodiment 3
[0038] The raw material matte glaze described in Example 3 is prepared from the following raw materials by weight percentage:
[0039] Feldspar 65.0%, alumina 4.0%, zinc oxide 10.0%, limestone 13.5%, calcined talc 1.0%, titanium dioxide 0.5%, zirconium silicate 0.5%, barium carbonate 0.5%, Suzhou soil 5.0%.
[0040] Firstly, various raw materials are weighed according to the above-mentioned ratio; secondly, they are added into a ball mill at the ratio of batch material: ball stone: water=1:2:1, and then 0.05% of the dispersant CMC is added to make a glaze slurry. The size of the glaze slurry is controlled to be less than 10 μm. The particles with a particle size of 80 to 87% are made into a slurry that is aged for 48 hours for use.
[0041] The prepared glaze slurry is applied to the unfired bone china greenware and fired at a temperature of 1140-1180°C to obtain a high-quality matte bone china product. The porcelain surface of the product is as polished as wax, and it has a smooth,...
