From Xinxiang Ceramic Mug Manufacturer,At present, according to the different decoration methods, the ceramic coffee mugs on the market can be divided into three kinds: glaze color, under-glaze color and in-glaze color. Because glazed cups are directly in contact with food, it is easy to bring heavy metals such as lead and cadmium into food, thus causing harm to human body. Cadmium mainly damages human urinary system, kidney, bone and so on, while lead affects human hematopoietic system.



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.
