How to choose lead-free ceramic tableware?

How to choose lead-free ceramic tableware? 1. When choosing ceramic tableware, you must choose a formal tableware market, and don't be greedy for petty cheapness and be fooled by unscrupulous merchants. 2. When purchasing, you can touch the surface of the tableware to see if there is any unevenness on the surface, and to see whether the pattern on the surface of the tableware is different in height. If there is, the ceramic tableware is glazed, because The baking temperature does not melt the glaze layer, so the tableware may have excessive lead, so it is not recommended to buy. 3. If the surface of the ceramic tile tableware has glossiness, and looks smooth and cannot touch the uneven pattern, then this is underglaze. Underglaze is that the pigment melts into the glaze by burning during the burning process. When white porcelin dinnerware touches our food, it will not remain in the food, so such tableware is safe and lead-free. 4. Most of the ceramic tableware we usually encounter in the supermarket are printed on the outside of the uranium. At this time, we must carefully touch the edge of the pattern with our hands. Because the pigment of the pattern needs to use heavy metals, it needs the protection of the uranium layer. In order to prevent the ceramic tableware from emitting harmful substances to the human body under the action of high temperature.
