Does fire, actually make metal Shiny? I mean, technically it should burn off all imperfections right? So, Metal should be shiny while in a fire.

Im sure that different metals react to fire/high temperatures differently.
Some metals burn, covering them in a black carbon type material.

But who knows, I never took much interest in that sort of science.
Im more of a biology man :)

That'd be a flame that isn't burning properly if it's getting black and sooty. A Impure flame of sorts.

Ever heard of flame polishing? It works on glass but I'm not too sure about metals. The metal could burn turning into a black carbon or it could be because of impurities in the flame. I'm going to go research this now, if I find anything interesting I'll edit my post.

Edit: It seems that it only works with glass and acrylic (plastic), I'm not sure that if this is because the metal doesn't get hot enough or because the metal is too porous. I have a friend who works in a welding shop later today I'll ask him his thoughts on it.

OOOOHHHH.... I thought you meant the music type. Flame Polishing man, just make sure the temp and metal work well together.

So if I was to throw a T-800 made of chrome into a fire, it'd be all shiny? Awesome! Thanks for the replies, now I just gotta research if Chrome in fire actually does become shiny.

I'm quite sure it doesn't work that way... Terminator is not your preffered source of info regarding physics [or anything actually]

You can use 'Temperature Programmed Desorption' to remove an adsorbate from a surface slowly, or you can use 'Flash Desorption' to just remove all the adsorbate at once. This works because as temperature increases, entropic effects become more important. Unfortunately, all this must be done in a vacuum, otherwise you will just succeed in oxidising the surface, which is a process that cannot be reversed by simple heating. So no, heating in a fire would just oxidise the metal. Ionic compounds containing metal ions are generally coloured because of electronic transitions that are caused by heating.

The question is, does Metal become Shiny if it's in fire. The answer is yes, Flame Polishing. Now my next question is, which I'm researching. At what temperature, does Flame Polishing work on Chrome.

Im assuming your not talking about fire when you suggest this method?

Nope; fire would just cause surface oxidation.

That and you cant have fire in a vacuum due to the whole lack of oxygen thing.

Well, you could have a molecular beam of oxygen that collides with... no. That would be overthinking it. Yes, the lack of oxygen would mean fire was out of the question. You'd just use a wire with electricity going through it as the source of heat (the resistance causes heat due to the current).
