Metal heating experiment

[Java Man]

yes. fire melts aluminum.

how is steel made? by melting iron and other elements...using very hot FIRES.

Actually fire is used generally with the ore and electricity with the steel.

Hmm. So then how about trying to melt a mix of common low-melt metals that were available, and get it up the high point of the fire temperature and seeing what color it pours at, in similar lighting conditions?

For what purpose? I'm going to assume you are on the "molten steel falling from the towers" rail-road.

The biggest problem you have is you are letting the tail wag the dog.

In order to know the temperature at which a material begins to exhibit a certain colour, in a certain light, you must first know

a) the composition of the material i.e. what it is. (saying aluminium or steel or iron isn't really good enough)

b) the temperature.

We don't know either.

Now, since no one can know what the composition of the material seen coming from the towers is, then no one can tell what temperature it is by looking at the colour. And vice a versa.

Your experiment isn't a very good one because there would be hundreds of different compositions of alloy produced by "mixing" low MP metals.

Yes, but it would be very hard for you to prove that something red hot is lead at say 280º C (below its melting point). Or aluminum for that matter. So while the composition can not be determined exactly we can certainly rule out elements.

Yes, the 2010 F150's use boron steel for part of the body, and some of the frame. Lighter than regular steel, (like 30% lighter) but something like 60% stronger. So do some of the 2010 model Focuses and Fusions. ALL of the 2011 Fiestas do to. And your friend is right. They do make a HELL of a mess.

My buddy found out by accident with an oxy-acetylene torch. He was quite pissed that no-one warned him when he first ran into it a few years ago (not in a Ford, I'll have to ask him). He thought it should have had a warning sticker or something. He said it almost cooked him.

Um, make that "Buick."

I don't think Packard made an engine that small past 1903.

eta: Except maybe a racer.

Yup, Rovers are Buicks.

But if some "random" combination (since that's what you're gonna get with fires and everything all mashed up) of low-MP metals _that would be likely to occur in significant quantities there_ heated up to 1000C glows yellow under (somewhat shaded?) daylight, then that's all that's needed to refute the idea it "must" be iron. It doesn't matter whether or not that specific combination occurred -- if any old random mix can do that, then there's utterly no reason whatsoever to assume it must be iron. As that's all that needs to be shown: that a random mix that would occur in the chaotic environment of the fire could glow the necessary color.

Why stop at metals? Why not glass as well? It satisfies the scenario too.
