3 Answers
I am intersted in finding out what is used to produce the colors in indoor fireworks. It seems that lots of addatived used for outdoor fireworks would produce toxic fumes ..... are these at low enough levels for indoors or are other chemicals used?
Don't worry I'm not planning on making any!

This thread is very ancient, but I have only just seen it. Barium salts are used for green (in small amounts), generally the most common colour is red as it is based on Lithium salts for indoor work (and has low toxicity), or Strontium salts in normal fireworks (Lithium is somewhat expensive). Titanium is most often used for white/silver sparks as it has cool fallout compared to aluminium. Magensium is rarely used in indoor work as it is very reactive with moisture, although Magnalium a magnesium/aluminium alloy produces a crackling effect.
The black snakes rely on a nitrated asphalt or pitch. White snakes aren't seen much now as they used to be based of mercuric Thiocyanate. Not a pleasant compound
