The medical stone pot is coated, not pure medical stone. Medical stone pot is an aluminum alloy pot with special coating, not a non-stick pot made of natural materials. Because its surface pattern is similar to medical stone, it is called "medical stone pot" and can be used directly on an open flame.
Medical stone pot has a very good refrigeration function, which can keep the dishes bright after stewing. Due to the unique function of medical stone, it can prolong the shelf life and prolong the cold storage time of dishes.
The choice of medical stone pot;
There are two kinds of defects: small bumps and pits. The raised part of the small bump is generally iron, which has little effect on the quality of the pot. If the bulge is on the concave surface of the pot, it can be removed with a grinding wheel to avoid blocking the spatula.
Pots are thick and thin, and thinner ones are better. Some medical stone pots may be thick on one side and thin on the other, which is caused by the dislocation of the model. This pot with uneven thickness is not good. When buying, you can turn the bottom of the pot upside down, put your finger against the concave center of the pot and knock it with a hard object.
