In addition to metal materials and chemical coatings harmful to human health, purple casserole is made of high-quality natural purple sand and fine-grained ceramic liner, which is absolutely safe and harmless to human body. Purple sand is a kind of clayey siltstone containing iron, which is composed of hydromica, kaolin, Yingshi, mica and iron. The main chemical components are iron oxide, silicon oxide, calcium oxide, magnesium oxide, manganese oxide, potassium oxide and sodium oxide. Purple sand has been used in cooking and drinking utensils for more than 1000 years. Modern scientific detection and analysis have proved that it does not contain any harmful elements.
On the contrary, purple sand is rich in various elements needed by human body and has health care function. Trace elements such as iron, iodine, copper, manganese, zinc, cobalt, chromium, selenium, fluorine, silicon, tin and vanadium in human body are closely related to the life activities of the body, and their importance exceeds that of vitamins. In purple sand, the content of iron oxide can reach about 8%, and the content of trace elements such as silicon and manganese is also relatively high. Other elements such as calcium, magnesium, sodium and potassium are also important elements needed by human body. Therefore, the inner container of purple clay pot, like medical stone, is a mineralized environment to help the human body absorb important elements.
If it is soup, purple sand soup pot should be the first choice.
