Is the glass on the tableware harmful to human body?
When buying ceramic tableware, it is easy to be attracted by the beautiful painted patterns on the tableware, but I don't know that it is this beautiful painted pattern that will cause harm to the human body. The drawing is colored glaze, which contains a variety of heavy metals. The brighter the glaze color, the more heavy metals it contains. It is best not to choose ceramic tableware with too bright color. At the same time, ceramic tableware is best soaked in mature vinegar before use.

Precautions:
1, choose ceramic tableware instead of glazed decoration, especially the inner wall of ceramic tableware should not be painted. You can choose underglaze or underglaze decoration. For example, blue and white is a kind of ceramics that people like to decorate with underglaze colors.
2, buy back the ceramic tableware, first soaked in 4 vinegar water to boil, so as to remove most of the toxic substances, greatly reducing the potential harm of ceramic tableware to human body.
3. Don't use ceramic tableware to store acidic foods and drinks such as juice, wine and coffee for a long time. Because the longer the ceramic tableware holds acidic food or drink and the higher the temperature, the easier it is to dissolve lead, which is equivalent to aggravating the toxic and side effects of lead dissolution.
4, whether the shape is geometric, whether there is damage, spots, bubbles, smooth. Ceramic products with prickly, mottled and even cracked surfaces are easy to overflow lead in their glazes and are not suitable for tableware.
