1, purple sand is characterized by compact structure, close to porcelain, high strength, fine particles and shell-like or stone-like fractures, but it does not have the translucency of porcelain tires.

The teapot contains 8% iron oxide, and the content of silicon, manganese and other elements is also quite high. It also contains metal elements needed by human body, such as calcium, magnesium, sodium and potassium. Therefore, using purple casserole to stew soup is very beneficial to our human body, and it is one of the ways for us to absorb the elements needed by the human body. Moreover, the cooked food is very fragrant and the nutrition is not easy to lose.

Purple casserole does not contain any chemical coating, and is rich in a variety of minerals and trace elements, which are very fragrant whether cooking soup or cooking. However, due to the high price of high-quality purple sand, some black-hearted manufacturers will use the soil dyed with dyes as the raw material of the inner container, so the quality of purple casserole is not easy to grasp. If you buy inferior purple casserole, the harm can not be underestimated.
