Medical stone non-stick pan is an aluminum alloy pan with special coating, not a non-stick pan 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. So the medical stone pot is coated, not pure medical stone.

In fact, the medical stone pot may be a non-stick pot, not a pot made of natural materials. The pot body is made of aluminum alloy, and then the outermost layer of the pot is coated with medical stone, so that the alloy is isolated from the ingredients to ensure non-sticking, and the pattern and color of the coating are the same as or similar to that of medical stone. Medical stone wok is not so tall, it is a kind of uncoated wok, which is out of touch with medical stone, or it is more suitable to call medical stone pattern non-stick wok.

Skills of purchasing medical stone pot

1. The surface of the pot should be smooth, but not "smooth as a mirror". Due to the casting process, all medical stone pots have irregular shallow lines, which is not a problem.

2. Check whether there are any defects. Defects mainly include small protrusions and small pits. The protruding part of the small protrusion 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.

3, the bottom of the pot is stained with fire, commonly known as the pot bottom, the pot bottom is not good, because it spreads fire slowly. It takes enthusiasm and time.

4, the pot is thick and thin, and the thinner is 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. The louder the pot rings, the greater the vibration, the better.

5, there are rust spots on the pot, which is not necessarily of poor quality, and the brightness and quality of the pot have little effect. Because the substance that brightens the pot is graphite, graphite is used as a refractory coating in casting.
