How to choose ceramic tableware?

Ceramic tableware is divided into three types according to the decoration of ceramic flower surface, namely on-glaze color, in-glaze color and under-glaze color, among which on-glaze color is the simplest and cheapest. But cheap is not necessarily a good product, you should be careful when purchasing, and comprehensively consider the performance of all aspects of ceramics. Buying ceramic tableware must be purchased in the regular market, and do not buy inferior products that are not produced by manufacturers. Under normal circumstances, when the ceramic tableware is soaked in acetic acid, the dissolution of lead should be less than 7mg/L, and the dissolution of cadmium should be less than 0.5mg/L.

In addition, pay attention to the color of the tableware when purchasing, touch the surface of the tableware with your hand to see if the inner wall is smooth and clean, and smell whether there is any odor. It is best not to buy ceramic tableware that is too bright in color. Usually, the brighter the color of the tableware, the easier it is for heavy metals to exceed the standard. It is recommended to buy underglaze and underglaze tableware with good raw materials.

The selection of ceramic tableware also depends on whether the shape of the tableware is straight and whether there are damaged spots. If it is gold ceramics, wipe it with your hands and it will not fade. It is best to tap a few times when buying. If the sound is crisp and good quality, if the sound is dull, it is mostly inferior. After buying it, soak it in vinegar before using it to remove the harmful substances in the ceramics.
