what chemical is rainbow flame crystals made of?

Question

It's a salt, but I dont know which one, can someone help me out?

Answer 1

It is probably a mixture of several different salts. I use NaCl, KCl, SrCl2, CaCl2 and CuCl2. I like to soak pine cones in solutions of these chemicals then allow them to dry. I toss them on a campfire for a burst of color.
