1. When purchasing ceramic water mugs, you must choose a regular market, and you must not be greedy for cheap products that do not have official manufacturers. According to national regulations, soak ceramic water mugs in 4% acetic acid, the dissolved amount of lead shall not exceed 7 mg/L, and the dissolved amount of cadmium shall not exceed 0.5 mg/L.
2. Pay attention to the color of the water glass when purchasing, and touch the surface of the water glass with your hands to see if the inner wall is smooth.
3. Smell whether there is any peculiar smell.
4. Do not buy ceramic water glasses with too bright colors. Usually the brighter the color of the water glass, the easier it is for heavy metals to exceed the standard.
5. In-glaze and under-glaze water mugs with strict raw materials and process control should be purchased.
6. Boil the water mug for 5 minutes or soak it in vinegar for 2-3 minutes before use to dissolve toxic substances.
