LOL! I seem to be getting a lot of replies regarding the gas statement so I will reply to you and do it one time.
Vaporized and gas are different in a major way.
You can certainly vaporize iron with a large amount of heat, but it is forever destroyed and is no longer iron. It cannot be reclaimed.
A spectrometer does this to a iron or steel sample and is a good example of destructive testing.
If a element can be said to be in different forms like a gas or solid, it must remain an element and not be destroyed.
I hope this clarifies what I said. I will put my phaser back in it's holster now.
Some things will break down to their component parts and gases do derive from combustion of some metals. But it is not Fe Gas.
Seems funny replying to a comment that I can barely recall making in 2003.
