From the brand point of view, Supor, Midea, are better brands of small household appliances, and more good friends will say Midea, but you can compare the materials of Midea and Supor in the shopping mall (this is more intuitive).

Who is safer, purple porcelain or white porcelain?

White porcelain is actually made of clay, but its surface has a layer of glaze. After being heated at high temperature, it will release substances harmful to health. Purple casserole does not contain any chemical coating, and is rich in various minerals and trace elements, which is very fragrant whether it is 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.
