When purchasing ceramic tableware, it's important to choose a reputable and formal market rather than opting for cheap, low-quality products from unknown manufacturers. According to national regulations, ceramic tableware should be soaked in 4% acetic acid, and the amount of lead that dissolves should not exceed 7 mg per liter, while cadmium should not exceed 0.5 mg per liter. Most products from regular manufacturers generally meet these safety standards. When selecting ceramic dishes, pay attention to the color and texture. Run your fingers over the inner surface to check if it feels smooth and free of roughness. A rough or uneven surface may indicate poor quality or improper manufacturing. Also, take a moment to smell the dish—any strong or chemical-like odors could be a sign of harmful substances. Avoid buying ceramic tableware with overly bright colors. These vibrant hues are often achieved by adding heavy metals to the glaze, which can increase the risk of exceeding safety limits. The brighter the color, the higher the chance of harmful substances being present. Opt for underglaze ceramic tableware, as it is typically made with stricter control over raw materials and production processes. This type of tableware is less likely to release harmful substances during use. Before using new ceramic dishes, it's a good idea to boil them in water for about five minutes or soak them in vinegar for two to three minutes. This helps to remove any residual toxic substances that may still be present on the surface.
