[TheForge] why doesn't cast iron oxidize and burn in the same way?(was: oil/wax finish, blackened steel)

[Andy Gladish]

It ain't all the tree's fault. I often compare my mind to a very small 
table- or any horizontal surface in my shop- it's completely full of stuff 
so when you put something on one side you automatically push something off 
the other side.
I still don't really "get" what's going on with the torch cutting, is it 
correct to think of it as a hyper-fast rusting process? It seems very 
different, since rust doesn't produce anything much like slag..

...Funny how someone with a decent size chunk of gray matter turned to rust
remembers the darndest things. This bit came right to mind when you asked
Andy but I can't recall one of my niece's name for nothing. Damn TREE!
