Plasma cutter for cast iron?
I guess that you would get a lot of
soot in the cloud of vaporized iron.
I'm guessing not. The amount of carbon is still small enough that, when
heated to that temperature, it would likely combine with atmospheric oxygen
just about a quickly as it came into contact with the air.
You might also get some carbides as products of heating the metal and
carbon that hot.
