How to choose ceramic tableware wholesale?2

How to choose ceramic tableware 1. To buy ceramic tableware, you must choose a regular market and store. Don't buy cheap products of inferior products from non-wholesale dinnerware suppliers. According to national regulations, when ceramic tableware is soaked in 4% acetic acid, the leaching amount of lead shall not exceed 7 mg/L, and the leaching amount of cadmium shall not exceed 0.5 mg/L. 2. Pay attention to the color of the tableware when buying, and touch it with your hands. Check the surface of the tableware to see if the inner wall is clean. 3. Smell whether there is a peculiar smell. 4. Do not buy ceramic tableware that is too bright in color. Generally, the brighter the color of the tableware, the easier it is for heavy metals to exceed the standard. 5. In-glaze and under-glaze white porcelin dinnerware with strict control of raw materials and technology should be purchased. 6. Before using the ceramic tableware, boil it in boiling water for 5 minutes, or soak it in vinegar for 2-3 minutes.
