The first way they made tetrazole was to pressurize hydrogen cyanide with hydrogen azide. Who wants to try it first?

I believe Angelfire supply much of the Disney corporation with its fireworks!, I think they also devised a compressed air system for launching shells.

Sure, you can make them, but no one really uses them. It's all nitrocellulose or carefully tuned AP compositions. Maybe a little bit of those exotic things to speed up the burn. The other chemical you may want to look into if you're actually interested is guanidine nitrate. The military might use those things, but they don't for civilian fireworks.

Do you have any examples of NC-based star compositions? I've only ever seen NC as a binder or with Chlorides in flame projectors.
There are a few commercial fireworks I believe use NC systems - Kimbolton's 'jumping jellybeans' for example. I always wondered how they formulated the coloured microstars.
If we can make great colours with a NC system I'd be interested to try some out - cost isn't as much of an issue where amateur experimentation is concerned.

yes you are right, i also think they seem to be working in the area of low smoke indoor / theatrical pyro.
nitrocellulose is also mentioned.............i would guess they mean more than coloured flame projecors
