Pyrosium is dumb as heck

[atomic1fire]

The only thing I use pyrosium for is a mix of pyrosium and thermite I call "(almost) instant wallremover"

I never bother carrying a lighter or welder because it's just easier to make enough of both in one beaker.

Also I don't think you can spray on walls, otherwise spray bottles of (almost) instant wall remover would be a good traitor marketing gag.
