A:heating the ore and carbon together. Air blast and charcoal (coke): 2C + O2 2CO. Carbon monoxide (CO) is the principal reduction agent. Stage One: 3Fe2 O3 + CO 2Fe3 O4 + CO2 Stage Two: Fe3 O4 + CO 3Fe O + CO2 Stage Three: FeO + CO Fe + CO2 Limestone fluxing chemistry: CaCO3 CaO + CO2 pedia
I don't know about the best kind to buy. I get mine in the camping section of my local store. I use salt and wipe it clean. then I oil it down and heat it. ready for use next time.
I was told that if you need to wash your skillet, you can use mild soap and arm water. But washing isn't necessary if you are pretty much cooking the same thing in it. For example, I have a skillet I use only for bacon. I wipe it down and put it away. The skillets i bought were from a local kitchen store which it probably your best bet verses say like Wal-Mart.
you're not supposed to wash a cast iron skillet in soap and water because it can rust. if you need to rinse it out quick that's ok, but you should clean it with salt and a cloth (the salt will scrub the food off), wipe the salt out, (very quick rinse with water if you need to), add a little bit of oil and rub it all over the pan, and heat it in the oven. once it's heated up then turn the oven off and just leave it in there to cool down. this is the proper cleaning method because it keeps the pan seasoned, so nothing will stick to it. between the salt and the heat, all the germs get killed so you don't have to worry about getting sick. there's many different brands of cast iron cookware, just look for one that feels nice and heavy, not cheap and light. i would look at store websites to see what stores in your area carry them.
