Thermate

[Crazy Chainsaw]

I hate to stem the flow of vitriol, but surely we're all - in ~enigma~'s words - 'big boy'*, and don't need to break off from calculations to insult eachother.

* Or girls, but I'd have hated to break the rhythm of my sentence.

It is not about calculations or insults it all eventually boils down to the truth, the best way to handle a Cter is to beat him senseless with the actual truth.
Worthless calculations without data can never stand, Guesstimates are useless.
The whole Idea is using thermite induced steel cutting, that does not imply thermite is the only absolute fuel or oxidation source, it is bulky and heavy there are better ways to do it than large amounts of thermite, one is use the energy in the steel to heat and cut the steel itself.
To do that all you need do is use enough thermite to start the process, then apply an oxygen source to the heated steel.

Those who propose huge amounts of thermite to melt steel have lost the argument from the start that they opened their mouths.

Go down to the graph "metal temperature by color"

Thanks for the charts. So, are these charts saying that any metals will appear these colors at these specific temperatures? My lack of knowledge about metals is showing, sorry.

Also, is it true that MIT said that the molten metal flowing out of the South tower is aluminum?

I don't think it's really possible to say too much about the nature of molten metals based on their appearance in pictures taken with standard cameras, especially when you don't know the precise settings and response characteristics of the cameras used. That's the kind of thing you need spectral imagers for.
