Ceramic tableware can be divided into three types based on ceramic floral decoration, namely overglaze color, underglaze color, and underglaze color. Among them, overglaze color has the simplest craftsmanship and the cheapest price. But cheap doesn't necessarily mean good goods. When choosing, one should be cautious and consider all aspects of ceramic performance comprehensively. When purchasing ceramic tableware, it is necessary to go to a legitimate market and avoid buying inferior products without manufacturers. In general, when ceramic tableware is soaked in acetic acid, the lead leaching amount should be less than 7mg/L and the cadmium leaching amount should be less than 0.5mg/L.

In addition, when purchasing, it is also important to pay attention to the color of the tableware. Touch the surface of the tableware with your hands to see if the inner wall is smooth, and smell for any odors. It is best not to purchase ceramic tableware with overly bright colors. Usually, the brighter the color of tableware, the more likely heavy metals are to exceed the standard. It is recommended to purchase high-quality underglaze and underglaze colored tableware.

When choosing ceramic tableware, it is also necessary to check whether the appearance of the tableware is neat and whether there are any damaged spots. If it is gold ceramic, wipe it with your hand and it will not fade, which is considered high-quality. It is best to lightly tap a few times when purchasing. If the sound is crisp and of good quality, but if the sound is dull, it is often a low-quality product. After buying it, soak it in vinegar before use to remove harmful substances from the ceramics.
