1. When the new medical stone pot is used for the first time, put it in cold water to boil, then rinse it. When the medical stone pot is dry, coat it with a layer of cooking oil, and then clean it after 2 hours.

2. The new medical stone pot is actually a non-stick pot. Compared with the ordinary iron pan, the non-stick pan only has an extra layer of PTFE. Tetrafluoroethylene is an anti-sticking coating with high temperature resistance. It should be coated on metal surfaces such as aluminum and iron plate, and the service temperature should be limited below 250℃. Generally speaking, when we cook, the temperature is below 200 degrees, and our health is still guaranteed.

3. It should be noted that the life of the non-stick pan is very long, because the tetrafluoroethylene coating will decompose little by little under the condition of friction heating. In fact, compared with iron pans, ordinary iron pans are more hygienic.
