# Testing thermite for chemical properties

I'm writing a movie in which a bunch of military explosive ordnance experts destroy a turbine with thermite and the local fire chief has to work out whether it is plain $$\ce{Fe2O3}$$ and aluminium powder thermite or military-grade thermite with other stuff in it.

1. How would he test for these ingredients and better be able to discern between the two?

2. And what sort of language would he use to translate his finding?

• The question is: Is there any military grade thermite ? I could imagine an addition of magnesium, but not sure, if it would make any additional effect. – Poutnik Jun 14 at 8:04
• @Poutnik, if they added magnesium, it would be for the purpose of making it easier to ignite. For all its reputation as a ferocious incendiary, thermite is surprisingly non-flammable. – Mark Jun 14 at 20:08
