Thermite

"Burns as hot as the devil's asshole, and can melt just about anything."

- Troike

 is a quest item in Fallout: New Vegas.

Characteristics
Thermite is a metallic composition of aluminum powder and iron oxide, which produces an exothermic oxidation-reduction reaction known as a thermite reaction, used to burn through metals and demolition.

In the quests How Little We Know or For the Republic, Part 2, Troike mentions he made some Thermite, enough to destroy the entire Omerta weapons stockpile with the tampered light in the basement of Gomorrah.
