In fact, in the words of merchants selling electric purple casseroles, other casseroles are glazed, and the glaze contains lead and is toxic. But the purple casserole is not glazed, so it is non-toxic.
As a kind of pottery, electric purple casserole is more sanitary and safer than other metal and organic products. Proper addition of iron oxide, manganese oxide and nickel oxide to produce ceramic products is a stable and mature production process, and qualified products will not endanger human health. Moreover, purple sand has been used in cooking and drinking utensils for more than 1000 years, so it does not contain any elements harmful to human body.
According to Compendium of Materia Medica, it is proved that natural high-quality five-color stone grease is one of the important raw materials for high-quality purple sand mud and purple sand mine.
The efficacy of five-color stone grease determines the health care function of purple sand products, and the quality of five-color stone grease determines the quality of purple sand products. Modern research shows that trace elements such as iron, iodine, copper, manganese, zinc, cobalt, chromium, selenium, fluorine, silicon, tin and vanadium 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.
As can be seen from the above, the electric purple casserole is non-toxic and has no harm to human health. What's more, the real purple casserole has many benefits to the human body, which is beneficial to people's health and worth choosing.
