Principles For Selecting Ceramic Tableware

When purchasing and using ceramic tableware, the following points should be noted:
1. When purchasing ceramic tableware, it is important to choose a reputable market and avoid buying inferior products without a formal manufacturer for cheap prices. According to national regulations, ceramic tableware should be soaked in 4% acetic acid, and the leaching amount of lead should not exceed 7 milligrams per liter, and the leaching amount of cadmium should not exceed 0.5 milligrams per liter. Most products from legitimate manufacturers can meet this requirement;
2. When purchasing, pay attention to the condition of the tableware, touch the surface of the tableware with your hand to see if the inner wall is smooth;
3. Smell with your nose for any unusual odor;
4. Do not purchase ceramic tableware with overly 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 more likely 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.
