Re: Hot and Green?

probably blue, actually.  in pyrotechnics, copper compounds are used
to create blue color in fireworks. when copper sulfate or copper
carbonate are used in mixtures, or as the oxidant, you get a nice blue
color (depending on your recipie).   be sure to avoid having any
sodium in there, though, or having the flame too hot, it will wash out
the blue color.
