Cast iron pans are cooking tools currently used by many households. There is a point about cast iron pans that the bottom of a cast iron pan is very fragile. If you use a metal spatula, it is easy to put some things under your arm. It is best to use wood or silicone spatula. However, is this really the case?
In fact, the bottom of the cast iron pan is actually elastic. It is not glued to the surface like tape, it is already integrated with the metal inside. It is very difficult to scrape the bottom of the pot with a metal spatula unless you are very hard. But sometimes you will find some debris when cooking, which is actually due to the carbonization of some substances in the bottom of the pot.
