What is the best material for hot pot?

From the health point of view, the iron pot is the best, but it is very easy to rust if it is not maintained regularly.

Stainless steel is the most common and durable. Not easy to stain, corrosion-resistant, and not scratched.

If you want to heat quickly, it must be a copper pot. Now old Beijing instant-boiled mutton still likes to use charcoal copper pot. However, after the copper pot is stopped for a period of time, the inner surface of the pot will react with water and oxygen to form a layer of green copper rust, that is, basic copper acetate or copper sulfate, both of which are toxic. Therefore, before using the copper pot, you must dip the cloth in vinegar, wipe it with some salt, and thoroughly scrub the copper rust before using it.
