The Selection And Purchase Of Ceramic Tableware

When purchasing and using ceramic tableware, pay attention to the following points:
1. When purchasing ceramic tableware, it is important to choose a reputable market and not buy inferior products without a formal manufacturer at a low price. According to national regulations, when ceramic tableware is soaked in 4% acetic acid, the leaching amount of lead shall not exceed 7 milligrams per liter, and the leaching amount of cadmium shall not exceed 0.5 milligrams per liter. The products of legitimate manufacturers can basically meet this requirement;
2. When purchasing, pay attention to the condition of the tableware, touch the surface of the tableware with your hands, and check if the inner wall is smooth;
3. Smell for any odor with your nose;
4. Do not purchase ceramic tableware with excessively bright colors. To make the colors bright, manufacturers will add some heavy metal additives to the glaze. Therefore, the brighter the color of the tableware, the easier it is for heavy metals to exceed the standard;
5. We should purchase underglaze and underglaze colored tableware with strict control over raw materials and processes.
