[0052] The present invention also provides a preparation method of enamel cookware, comprising the following steps:
[0053] 1) Preparation of glaze slurry: put black glaze and white glaze into a ball mill, add 50 to 200 parts of water alcohol at the same time, and ball mill for 10 to 24 hours to obtain glaze slurry; the weight ratio of water and alcohol is 1:1;
[0054] 2) Cookware body pretreatment: preheat the cooker body at a high temperature of 500-800°C;
[0055] 3) Preparation of enamel cookware: uniformly spray the glaze slurry prepared in step 1) on the preheated cookware body in step 2) to prepare enamel cookware.
[0056] In the present invention, the purpose of adding black glaze, white glaze, and water alcohol to a ball mill for ball milling is to obtain a homogeneous glaze slurry; in the embodiments of the present invention, the ball milling time is 10 to 24 hours; in other embodiments , the ball milling time is 15 to 18 hours.
[0057] In the present invention...
