When purchasing ceramic tableware, it's important to choose a reputable and formal market. Avoid cheap products from unknown manufacturers, as they may not meet safety standards. According to regulations, ceramic tableware should be soaked in 4% acetic acid, with lead content not exceeding 7 mg/L and cadmium not exceeding 0.5 mg/L. Reputable brands typically comply with these requirements. When selecting tableware, pay attention to the color and texture. Check the inner surface by touch to ensure it is smooth and free of rough edges. A smooth finish indicates better quality and less likelihood of harmful substances leaching out. Smell the tableware before buying. If it has an unusual or chemical-like odor, it may contain unsafe materials. This is especially important for items that come into direct contact with food. Avoid brightly colored ceramic dishes. Bright colors often mean more heavy metals are used in the glaze to enhance appearance. The more vibrant the color, the higher the risk of exceeding safety limits. Opt for underglaze ceramics, which have stricter control over raw materials and production processes. These are generally safer and more durable than overglaze or decorated pieces. Before using new ceramic tableware, it’s a good idea to boil it in water for 5 minutes or soak it in vinegar for 2-3 minutes. This helps remove any residual toxic substances that may be present on the surface.
