Five, buying skills

According to the national regulations, when ceramic tableware is soaked in 4% acetic acid, the dissolution of lead should not be greater than 7 mg/L, and the dissolution of cadmium should not be greater than 0.5 mg/L. The products of regular manufacturers can basically meet this requirement.
2. Pay attention to the color of tableware when buying, and touch the surface of tableware with your hands to see if the inner wall is smooth.
