What is the difference between wok iron and cast iron?
As long as the non stick pot, the surface of the pot must be non stick material. There are two main types of material, 1, 2, Teflon; ceramic powder. The non stick has been inseparable from smoke-free, so the pot is used for alloy, through the anode hard oxidation technology. This kind of pan is super hard, acid, alkali and corrosion resistant. Teflon, the best in the world not sticky materials, but a considerable gap between the quality, some are not durable. Ceramic powder, this quality is better, see, look at it. There is also the bottom of the pot work, because the new pot bottom has guided magnetic steel bottom.
All non stick pans and smokeless pans are alloy and do not use iron. The reason is that the iron is not very good for heat conduction and soot. As long as it is called non stick or no smoke, it is alloy pot.
Pig iron and cast iron, there is also called "refined iron", only two.
