Heh. I never have good luck doing bacon in the cast iron, I always end up with a bunch of crumble that stick to the bottom. I'll use bacon grease in my cast iron any day of the week, though.

Note that stainless steel DOES rust. It is a common misconception that it doesn't. Stainless steel doesn't STAIN (very easily). That being said, some grades of SS rust faster than others. Aluminum doesn't rust. Many SS pots have an aluminum or chromium oxide finish (i.e. a nonrusting metal blend; also good for heat transfer),
The only metals that do not oxidize (Rust) are platinum and gold. All other metals do oxidize, including Aluminum... Stainless steel has a VERY low oxidation coefficient. I tried to find a graph of the SS corrosion coefficient; however, i couldn't... The SS graph looks like the graph of a cube root. Under normal conditions, it will develop a thin layer a oxidation, and stop oxidizing. This layer of oxidization does not look like rust.. Chromium, is one of the elements that are used to create stainless steel.... If you would like to take the time to read the below article it has a lot of good information in it. http://www.apv.com/pdf/catalogs/apv_corrosion_handbook_1035_01_08_2008_us.pdf

Ken, get one of these.. http://www.surlatable.com/product/PRO-890731/Le-Creuset-Flame-Cast-Iron-SkilletI have a different Sur la Table cast iron pans.. They are quite expensive, but worth every freaking penny....

Don't confuse rust with oxidation. Rust is a laymen term for metals, typically with iron content, that fall apart (become oxide dust) following the oxidation process. Some metals as you correctly mention, gain a layer of surface oxidation but that layer then protects the underlying metal from further exposure to oxygen. This process is not "rusting" as the term is used.

Ya, and good example of oxidation without rust is copper. Turns a nice shade of green. Aluminum that has been in the elements for a while is a real bitch to weld. That crap leaches out no matter how much you grind it down to get out of the oxidized layer.

Next on the Axiom Metallurgy Corner - Practical conductivity differences between gold, silver and copper.
Just relax and let it dissolve under your tungsten.

And kids, never try to clean carbon steel with acid. Just saying... Sounds like a science experiment to me. Mark. Buy some acid and report back. Don't forget to wear a helmet though. Safety first...

Since we're now in chemistry class, it can be noted that "oxidation" doesn't necessarily involve a reaction with oxygen, although that's how it originally got that name. It's actually the loss of electrons from the oxidized atom to the other "reduced" atom, which may be oxygen, but also others such as chlorine.
Copper when oxidized by oxygen shows the colors exhibited by progressively older pennies, from the reddish-brown cuprous oxide(Cu(2)O)to the almost black cupric oxide(CuO). A greenish color on copper is the result of oxidation by chlorine to the chloride in the presence of moisture.
