[0002] The current Crystal Linglong glaze is used in white porcelain. Since white porcelain is low-temperature plain-fired and high-temperature glaze-fired, the body of Linglong and white porcelain can be fired at one time; and if the Linglong glaze used for white porcelain is used for bone In terms of quality porcelain, when the bone china is fired at high temperature and glazed at low temperature, if the Linglong glaze used for white porcelain is still used, then the fired bone china Linglong products will have poor transparency and high cracking rate.
In addition, the conventional method of pouring Linglong glaze for Linglong products is to use a glue dispenser or other methods of water glaze pouring. The pouring efficiency is low and leaks are prone to leaks. If traditional bamboo or wooden tools are used, the baked color will be better. Linglong products are prone to color and pattern dirty, and after glaze firing, Linglong products are prone to quality problems such as glaze leakage

[0031] Step A: Mix the mixed total weight with water in a ratio of 6:4;
[0032] Step B: After the mixture is put into a quick ball milljar and ground to fineness, pass through a 250-mesh sieve to get fine powdery ingredients.
[0033] Step C: Send the fine powder ingredients obtained in step B into a calcining vacuum kiln, calcining at 1200-1600° C. for 16-30 hours, and cooling naturally to obtain a transparent and smooth crystalfrit.
[0036] Step A: Mix the mixed total weight with water in a ratio of 4:6;
[0037] Step B: After the mixture is put into a quick ball milljar and ground to fineness, pass through a 250-mesh sieve to get fine powdery ingredients.
[0038] Step C: Send the fine powder ingredients obtained in step B into a calcining vacuum kiln, calcining at 1200-1600° C. for 16-30 hours, and cooling naturally to obtain a transparent but slightly rough crystalfrit with pores.
[0041] Step A: mix the mixed total weight with water in a ratio of 5:5;
[0042] Step B: After the mixture is put into a quick ball milljar and ground to fineness, pass through a 250-mesh sieve to get fine powdery ingredients.
[0043] Step C: Send the fine powder ingredients obtained in step B into a calcining vacuum kiln, calcining at 1400-1600° C. for 16-30 hours, and cooling naturally to obtain a transparent but slightly rough crystal frit with pores.

[0045]
[0046] As shown in Table 2, the crystal frit prepared by the present invention has good light transmittance and reduces bubbles in Linglong glaze. This is because the amount of quartz will affect the refractoriness of the mixture. If the proportion of quartz is too high, the refractorines...

Abstract
The invention provides a method for firing bone-china exquisite products. The method comprises the following steps of: 1, firing crude blanks of to-be-fired exquisite products at high temperature to 850-870 DEG C and preserving the temperature between 860-1000 DEG C for 0.5-2 hours; 2, heating to 1200 DEG C and preserving the temperature between 1200-1300 DEG C for 1-2 hours; 3, heating to 1400 DEG C and preserving the constant temperature between 1400-1500 DEG C for 3-5 hours; 4, cooling to 900 DEG C and preserving the temperature between 900-1080 DEG C for 1-2 hours; and 5, cooling to 500-600 DEG C, preserving the temperature for 1-2 hours, slowly cooling, taking out of the kiln and obtaining the products. The method provided by the invention has the beneficial effects that crystal and exquisite glazes fired by adopting the method are incapable of cracking and leaking; and the cracking of the blank body is reduced through the combination and the matching of the exquisite glazes, the blank and blank glazes.
