Embodiment 1
[0031] The specific implementation steps are as follows:
[0032] (1) Mix 5g feldspar powder, 2.5g quartz powder, 0.5g kaolin powder, 5g glaze fruit powder, 2.5g waste concrete powder and glass powder 1:1 mixture, 2g talcum powder and 0.5g zinc oxide powder, and stir well .
[0033] (2) Heat the mixture in step (1) to 1160° C. in a heating furnace and keep it for 60 min.
[0034] (3) Then, the temperature is lowered and cooled in a heating furnace.
[0035] (4) Detect basic properties such as whiteness, Mohs hardness and water absorption of the prepared ceramic glaze.
[0036] The ceramic glaze prepared according to the present invention is compared with the ceramic glaze prepared by the original formula. The formulas of the examples are compared with the original formula as shown in Table 1, and the comparison of basic properties is shown in Table 2.
