Some of it is black powder, esp in rockets. Some is coarse grains, some fine.
Some is Armstrongs explosive, which if I remember correctly is BP and pottassium chlorate(Very sensitive!). If you want BP, I strongly suggest that you just buy it.
Trying to "harvest" it from fireworks could result in having to learn to tie your shoes with no fingers!

This is best answered with another question.
Do you have a video camera and tripod?
The stuff in firecrackers could be anything. Experiment at your peril. Take video, so folks know what happened when they find you.
Bad Idea!

It is mostly bp but alot more expensive than in a can bout from any sporting good reatailer.
I've heard of guys making their own firecrackers with black powder. If this is what you're after, I suggest searching the web. BE VERY, VERY, CAREFUL! KD
You have no idea, how course the black powder is, therefore no idea of the burning rate of that particular powder or the pressures generated. Its kind of like playing russian roulette with 6 chambers loaded. Something will happen, depending on the amount of powder used, the question is; will you and the firearm survive?

Firecrackers also have additional chemicals added to make different colours. There are a couple of documentaries on Discovery Channel about the making of fireworks (and one on History channel about the fireworks factory explosion in the Netherlands?).
Everything is tightly controlled and non-metallic, in separate buildings away from everything else. They are the trained professionals, I'm sure I wouldn't want to engineer or reverse engineer a firework (aka controlled bomb).

When I was 14 back in "Jolie olde" I made a cannon out of 1" mild steel in metal shop, about 7" long,3/8" bore. dumped the contents of a "Brock's Cannon" banger (Fire-cracker) in it and a large split shot paper wadded. Used my gym bag as a catcher to see if the projectile would penetrate or dent it. Upon firing the cannon blew back about 30 feet, the split shot killed my bag, went through my gym shorts and set them smouldering travelled into my math text book about 3" edge-wise in 2 pieces ruining the book. This first firing was in a stone-bridge under-pass to get max echo, our ears rang for a helluva time, didn't even hear the broad #####ing at us for awhile. So I guess it's like BP, for firecrackers just use Pyrodex it makes a good bang in heat shrink tube which is re-usable.

Ok. I'm probably one of the bigger risk takers here. Some write me off as plain crazy, so when I say don't.....don't.
Leave the fireworks for the long weekend in May.
There are some that contain pressure sensitive (in small quantities, but enough to be dangerous when combined with the rest of the firework) compounds.
If you want a small sample of what can hapen, take a .22 cartridge apart and dump the powder. Now gently try and scrape the primer compound out from around the rim with a paperclip. It's not enough to do any damage, but don't be holding it up to your eye while doing this. Better yet, don't do it at all. You'll get through a few, and then one will go off without warning with about the force of 5 cap gun caps. You're doing the exact same operation as the first four. You did nothing different at all and BANG!
Fireworks are great fun but aren't great for lab experiments.
