1. comparison of features: the cast iron pan is made of pig iron or iron alloy. The main features of cast iron pan are heavy weight, high density, uniform heat dissipation and stable temperature. The cast iron pot also has good wear resistance and corrosion resistance. Cast iron pans rust easily and need special care and maintenance. It is easier to use and maintain than a cast iron pan, and the effect of stewing or frying food with a cast iron pan is better.

2. Comparison in use: When the temperature of the fire exceeds 200℃, the cast iron pot will control the temperature transmitted to the food at 230℃ by emitting certain heat energy, while the thin iron pot will directly transmit the temperature of the fire to the food. For ordinary families, it is better to use cast iron pan, because cast iron pan has the advantage of less fine iron impurities, so the heat transfer is relatively uniform and it is not easy to appear.
