Embodiment 1
[0026] Example 1 Preparation of Easy-to-Clean Ceramic Glaze
[0027] 1. Yijie ceramic glaze is composed of the following raw materials calculated by weight percentage: potassium feldspar 33-35%, kaolin 10-12%, calcium oxide 13-15%, magnesium oxide 8-10%, zinc oxide 6-8% , Quartz 24-26%.
[0028] 2. The preparation method of the above-mentioned easy-to-clean ceramic glaze comprises the following steps:
[0029] S1. According to the formula ratio, mix and pulverize each raw material, and perform wet ball milling to obtain glaze slurry;
[0030] S2. Remove iron from the glaze slurry in a 18000 Gauss iron remover;
[0031] S3. Pass the glaze slurry after iron removal through a 250-mesh sieve, and the sieve residue is less than 0.02%;
[0032] S4. Stale the sieved glaze slurry for 24-26 hours, and set aside;
[0033] S5. Prepare a ceramic glaze according to a conventional method.

Embodiment 3
[0068] Example 3 Optimization of aging time of glaze slurry
[0069] 1. The raw material formula of Yijie ceramic glaze is as follows: potassium feldspar 35%, kaolin 10%, calcium oxide 13%, magnesium oxide 10%, zinc oxide 6%, quartz 26%.
[0070] 2. Preparation steps:
[0071] (1) The preparation steps of Group 1 are as follows:
[0072] S1. Mix and pulverize the raw materials of Yijie daily-use ceramic glaze according to the proportion of the component formula, and perform wet ball milling. The wet ball mill is carried out according to material: stone: water = 1:1.8:1, and glaze slurry is obtained;
[0073] S2. The above-mentioned glaze slurry is deironed in a 18000 Gauss iron remover;
[0074] S3. Sieve the glaze slurry after iron removal, the fineness of the sieve is 250 mesh, and the sieve residue is less than 0.02%;
[0075] S4. Stale the sieved glaze slurry for 21 hours and set aside;
[0076] S5. Prepare a ceramic glaze according to a conventional method.
