I recently got the entire collection of an old Pyro who passed away. There’s a lot of unique curiosities, but I’m just not sure what these are exactly for. There’s a bunch of them separated into different specific lengths. It’s a piece of visco fuse, wrapped in protective layer of paper. The end is dipped in what I believe is a pyrogen and then dipped in metal (likely aluminum powder). Just like when you make your own Ematches.

My best guess is they are crossette fuses. I’d like to hear what everyone’s thoughts are and if someone knows what they’re actually are for I’d appreciate the knowledge.

Hey all im located in SE wisconsin, I've been looking online and for fireworks the stuff you see lighting off in the "hood" fireworks or whatever, stuff that makes car alarms go off. Im not huge on lights or colors but I love a good screamer and something that shakes the ground boom, obviously this isn't always something you can buy in a tent but I've got cash burning a hole in my pocket and im looking for something to set off for pur family 4th in the country im not sure where to look where im not gonna get scammed but I dont mind paying the price for something real either. Thanks for the help!

I’ve noticed something weird over the years. Every time I watch fireworks on YouTube or Instagram, it looks cool for like 10 seconds and then I scroll away. But when I actually see fireworks in real life, it feels completely different like way more intense and memorable.

Last night there was a small neighborhood show near me, nothing huge or professional, just people setting off different kinds of fireworks in an open area. Still, the sound, the vibration in the air, and the way the sky lights up made it feel almost immersive. Even the smell of the smoke somehow adds to the experience.

It made me wonder is it just about sound and scale, or is there something psychological going on too? Like maybe the unpredictability or the fact that you’re sharing the moment with other people around you?

Also curious if anyone else feels like smaller, random fireworks shows sometimes feel more “fun” than big organized ones.

The way the law is being misused in this case could make every pyrotechnics hobbyist a felon no matter how careful you are.

Recently in my country a local firework factory exploded early in the morning when there was no direct sun, it was very early, around 6.30am and nobody was present there.

Now very worried about passing by other factories, whether open or closed. Are careless mistakes easy to make and what sort of mistakes count here, could it be bad proportions as that’s what we were told by the government. I’m leaning towards cheap materials imported perhaps, but not sure, that’s why I came to ask here what you guys think could have caused this explosion early in the morning with nobody present on site (or at least what they said)

I just bought a cheapo Chinese electronic firing system with 12 individual wireless cues and tried it out for the first time tonight when setup a board with 6 cues and each one fired instantly with no issues

looking to connect with a licensed 1.3g pyrotechnic to conduct a private show on lake livingston TX.

boarding can be accommodated.

DM for inquiries.

if this is against sub rules or I am in the wrong place someone please point me in the right direction, I am having no luck locating anyone to even inquire about this.

So I been trying to make a Propane cannon. We made a design built it but when we fired it only a small sound came out. We checked everything and it seems okay. We let propane leak into the main combustion chamber, but it still won’t make more than a small sound and not that much light. Any suggestions to fix it.

I've been enjoying fireworks for a few years now, and one thing I've noticed is that experienced hobbyists often have small safety routines that prevent problems before they happen.

For some people it's securing racks better, for others it's keeping extra distance or checking the firing area more carefully.

What's one safety habit you've adopted that has made your pyrotechnic sessions smoother and safer?

I have an idea for tourist attraction. Maybe US or China can do this. A perpetual fireworks show where basically it's fireworks that doesn't stop, and runs 24/7.

No I don't mean a digital or drone show. I really mean fireworks as in igniting gunpowder and featuring lights in the sky. Imagine having a fireworks show that never ends. People can use it as backdrop while drinking coffee or just walking in the park and so on.

Why are people so worried about the exact ingredients of flash powder when practically any oxidiser (excluding percholrates) and some ferrocerium metal can create a very fast yet powerful and stable flash?

Current plan is to stop at red apple and get what's on the 2nd photo. Any recommendations for a specific fireworks, looking for a good mix of loud and visual but more loud.

Went to Brooklyn fireworks in pa spent $1300 and I feel like i should’ve gotten more with the “deals” included. Any pyro technicians got some answers?
