Is burning copper dangerous?
I am asking because I was camping and tossed some copper dust in the
fire to make the flames colorful. The flames were really nice, but
some drunken guy in the next camp was having a fit about it, saying
that burning copper emits dangerous fumes that when breathed are toxic
and of course, according to him, ALL the smoke was going his
direction.

The stuff is sol commercially with no particular warnings. OTOH, inhaling
any smoke is not good as it contains particulates.
