Hey, Just wondering how I would be able to make pyrotechnics suitable for use on an indoor stage. I have done some brief googleing and stuff like silver jets, silver fountains, sparkle pots and flame pots are the look that I am after.
These will be used in combination with a fog machine (liquid, not dry ice based)

Electronic triggering would be best for them.

Well, you outlined the basics, you'll be looking exclusively at low explosives, primarily flash pots and squibs are the best place to start, so you should be reading up on oxidisers and fuels, reaction potentials, ways to speed up or slow down a composition... Then buy some shit and start muckin' around.

Ghost is right, but ill go one further...look into magnesium and potassium nitrate, avoid the organic peroxides,
