What are the ways to identify whether bone china tableware is toxic?

There are 7 ways to distinguish whether bone china tableware is poisonous: 1. Choose bone china tableware, try to choose the ones that contact the food are without patterns or decorated with gold. Of course, high-temperature underglaze is the first choice for supermarkets. 2. Bone china tableware bought back can be soaked and boiled in vinegar water first to remove some toxic substances. If the color of the tableware changes obviously or the color of the white porcelin dinnerware is directly touched, it is recommended to give up directly. 3. Do not use bone china white porcelin dinnerware for a long time to contain acidic beverages or foods, such as fruit juice, wine, coffee or acidic dishes. The porcelain will react in a long time and dissolve more harmful substances such as lead and cadmium. 4. When choosing bone china tableware, you can see whether the shape of the utensils is correct (without deformation), whether there are breakages, bubbles, pinholes, thorns, cracks, etc. The vitreous glaze layer on the surface of the porcelain is to place the inner body of the porcelain, painting materials, etc. in contact with food. Cracks will make it contact and easily dissolve materials such as lead and cadmium. Therefore, cracked porcelain tableware is not suitable for use. 5. decorated with gold and silver patterns should not fade when wiped by hand. It is better to not fade. If you prefer this type, you can choose utensils that will not touch your lips and food, and should not be placed in a microwave oven. 6. The light and crisp sound of porcelain tableware is completely fired. This type of porcelain is better. The dull or dull sound indicates that the porcelain has not been burnt well. Maybe the type of porcelain is not correct, so it is not suitable to choose. 7. When choosing a set of tableware, look at the type and color of the utensils based on the above.
