Method of Removing Toxic Substances from Ceramic Coffee Cups
Glazed enamel can be easily identified by visual inspection and hand touch. If the picture is not as bright as the glaze, the hand feel is not smooth, and even the edge of the picture has a protruding feeling, it should be carefully purchased. If you buy a poor quality ceramic cup carelessly, you can boil the cup for 5 minutes with boiling water before use, or soak it in vinegar for 2 to 3 minutes to dissolve the toxic substances in the cup.
