The cooking pot is good or good wrought iron
Pig iron pot is not easy to rust, heat transfer evenly, a trace of iron content will dissolve into the food.
Beneficial to the body. Wrought iron pot is crisp, not easily broken, but easy to rust, heat transfer and heat dissipation are faster. Each has its advantages and disadvantages, but generally speaking, I am inclined to live in the wok, and the conclusion is that the pig iron pot is good.
