Re: safe chemicals to color flames?

That is pretty cool. I mixed up some borax with some %90 ethanol, I had
to substitute a couple drops of muriatic acid and it worked! A light
green flame.

I'll try making some copper salts later.

I don't know about potassium nitrate though, I would probably have to
get some potash lye or is their an easier way to make it?
