1. The best soup pot is made of stainless steel, which will neither rust nor stick to the pot, with fast thermal conductivity, high heat transfer, strong material and durability; However, it is easy to be heated unevenly, resulting in nutrient loss and poor heat preservation performance, and it is not suitable for storing food for a long time.

2, aluminum pot: strong thermal conductivity, low price, light and easy to use; The material is soft, easy to deform and easy to change chemically with food.

3. Non-stick pan: easy to clean. If the coating of non-stick pan is damaged, harmful components will decompose, which will affect human health.

4. Copper pot: Good thermal conductivity, uniform heating, rapid temperature rise and drop; However, the price is relatively high and the maintenance is very laborious.
