Some time ago, my family wanted to buy a rice cooker. I went to the physical store and bought a beautiful one. I also learned about my concerns on the Internet. It can be clearly told that ceramic rice cookers are not poisonous.

Because it is high-temperature fired clay, as long as it is not collected in areas with high heavy metal content and high radiation, there is no problem, but some ceramics should be colored before firing. The general coloring raw materials are all chemical raw materials, which are unsafe. It is best to buy white or white ceramics.

Some ceramic utensils are harmful to human health because they are decorated with glazed colors. Glaze contains harmful metals such as lead. People who ingest a certain amount of lead will have symptoms such as vomiting, nausea and abdominal pain. Lead can affect the functions of hematopoietic, nerve, kidney, blood vessels and other organs. Therefore, ceramics are used

Pay attention to the following questions when using: 1.

Don't use glazed decoration when choosing ceramic tableware, especially don't paint the inner wall of ceramic tableware. You can choose to decorate with underglaze or underglaze. For example, blue and white is a kind of ceramics that people like to decorate with underglaze colors.

2.

The bought ceramic tableware is soaked in water containing 4% vinegar and then boiled, which can remove most toxic substances and greatly reduce the potential harm of ceramic tableware to human body.

3.

Do not 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.
