Ceramic tableware is very popular in modern times. Most household tableware is made of ceramics. With the progress of the times and the development of technology, the styles of ceramic tableware are more colorful. At the same time, we need to pay special attention to the selection of ceramic tableware. After all, there will be some unqualified ceramics on the market. Long-term use of glaze color containing lead and other metals will cause certain harm to human health. So how to choose ceramic tableware?
1. The plastic imitation porcelain bowl may be toxic, and the porcelain tableware with poor quality of hairy crab may contain harmful substances such as heavy metals, so it is not recommended to buy. In addition, it is best not to buy tableware with patterns inside the food.
2. Some ceramic tableware are bright in color, probably because the inner wall is coated with a layer of glaze. When these tableware are filled with boiling water or acidic or highly alkaline drinks, lead, cadmium and other heavy metal elements in the glaze are easy to precipitate into the solution, causing harm to human health. If discoloration is found, it is best not to use it for food.
3. Do not put the ceramic tableware inlaid with gold edge in the microwave oven for heating, otherwise it will easily lead to the melting of gold powder and pollute the food. Now many people will buy a disinfection cabinet to disinfect the colored porcelain at home, but it is not recommended to often use the disinfection cabinet to disinfect the colored porcelain, because the internal temperature of the disinfection cabinet can be as high as 200 ℃, and the colored porcelain tableware contains lead, cadmium and other heavy metal elements, which are usually stable, but easy to precipitate under high temperature.
4. When purchasing ceramic tableware, you should be able to see the color with your hands and feel whether the inner wall is smooth and clean; You can also smell it with your nose. Don't buy it if it smells. You can also listen to the sound of ceramics. If the sound is clear and pleasant, it means that the ceramic has no crack, no damage and good quality.
