I'm trying to get a variety of colored flames by dissolving salt and methanol (after the fashion of this YouTube video et al.: http://www.youtube.com/watch?v=eRNLqTfIjQo"). I'm doing halfway alright with strontium chloride solution and boric acid solution, but having some trouble: the boric acid solution burns green for a little while but then turns yellow; the strontium solution is a bit dodgy, giving only intermittent red flames. Both solutions bubble and hiss: the boric acid solution hisses when the flame is yellow; the strontium solution hisses all the way through. Worse, I'm not having luck with sodium chloride or potassium chloride or cupric chloride. Regarding NaCl and KCl, I can't really get either to dissolve in methanol. As a consequence, I just get the clear/blue methanol flame, not yellow nor purple. Anyone have any advice? As for cupric chloride, I get a green flame, not the blue one from the video (starts out looking rather green, seems pretty blue after a little while).
