1. Material: Fine iron pots are made of high-purity pig iron, while cast iron pots are made of pig iron, scrap steel, recycled materials and other raw materials mixed and melted.
2. Density: Comparatively speaking, cast iron pans are denser and better able to withstand different temperature fluctuations than fine iron pans.
3. Weight: Since fine iron pans are not as thick as their cousins, they are relatively easier to maneuver.
4. Maintenance: Because of the different production processes, the surface of fine iron pots is not coated with paint or polished, and care needs to be taken to prevent rust during use; while cast iron pots are usually coated with a surface layer of grease to prevent oxidization, but after a certain period of time, they may become dull and need to be cared for and polished frequently.
5. Thermal conductivity: Fine iron pots transfer heat faster than their cousins, so if you need to cook food quickly at high temperatures, a delicate compact model may be your first choice; if you need to simmer or steam food slowly, a cast iron pot is more suitable for you.
All in all, the type of iron skillet you choose depends on your taste, cooking needs and budget. Due to its longevity and durability, you should focus on credentials and quality when choosing one and take good care of it regularly.
