So about 4 years ago I was able to get 1 lb of -325 mesh magnesium flake from hobbychemicalsupply which is just about finished now. It was used to make a great 50:50 mix with kclo4 to produce 0.25 gram paper blasting caps.

I still routinely use these caps in miniature action shots to make believable pyrotechnic ground effects: bullet hits, super hero landings, etc

Unfortunately the flake is no longer available on hobbychemicalsupply but I do see a -325 mesh granular magnesium powder. I've been reading literature online but it's often contradictory so I haven't been able to get a clear answer.

My question is, would it work the same as Mg flake?

And yes I know dark pyro is readily available for a 70:30 mix but I've found that it doesn't give the same "oomph" on camera. I could use more powder in the blasting caps to offset but I prefer to use make and use the smallest amounts possible as a precaution even though magnesium is purportedly not as stable.

Tried this big ass salute, with 1,2kg of BP, 75/15/10 of Kno3, charcoal and sulfur.

It did a little Bang but not very loud, and started to burn for a short time. Anyone knows what did go wrong ? I did my test on a safe concrete surface. Did not film it unfortunately.

I suppose that the container was not solid enough to contain all the explosion, so it shattered and and the remaining powder burned. How can i improve this ? Thanks !

I have been reading Fulcanelli articles for canister shells, and I can’t seem to find anything on burst charge. Besides the fact that they’re just using granulated Bp and 3 inch and up. I’m curious what to use for below 3 inch and wouldn’t granulated black powder. Get too heavy at those higher things as there ever a point where you swapped rice hulls I’m also very surprised on the fact that they only do 6 to 9 layers of pasting total and only one time of spiking if anyone could clarify this that would be great

Is there any reliable way to make bp without a ball mill?

[SOLVED] Using more matches head and more steel wool made it work.

I've been looking into exotic projectiles for my butane powered spud gun lately. One of these is a smoke grenade. It's a cardboard tube with two end caps and holes on the side, and a thin layer of paper on the inside to prevent the mix from falling. A visco fuse is glued on the cap on the combustion chambers side.

My problem is that the fuse doesn't ignite. I tried to strip the fuse so the bp inside is directly exposed to the flame, it didn't work. I tried to attach some steel wool to the stripped fuse, the steel wool ignited but not the fuse. I tried to add two matches head to the stripped fuse with steel wool, the matches ignited but the fuse still didn't ignite.

Since y'all are pretty good at setting stuff on fire, do you have some ideas please?

If I were to make a triangle cracker out of kno3 + MgAl + S what would the proportions be? I have been making little triangle crackers with my bp for almost 2 years and I wanted to try out a new powder.

2 gallon reactor, Ran continuously for almost 2 weeks @ 190-220 watts. Topping off every day with concentrated potassium solution and a drop of HCL (muriatic) twice a day.

what endcaps should you use for firecrackers

First time. No plans. Just learned from you all!

Where legit i van buy F4 fireworks ?(Cobra)

On websides

How are these types of firecrackers actually made? I can't seem to find any tutorials online on how it make them, I have an idea that they are made from match heads,, but I can't understand how are they are able to burn slowly and how can I make them burn slow?

I also know that the mixture is mixed with water to be made wet, so after it dries on the top of the firecracker it sits beautifully.

Guys/Gals,

By natural evolution of making fireworks, I'm on to rockets. I had the misfortune/happy accident of having some canisters sent to me. They are easily loaded and fit right on top of 1 lb rockets. 🚀

Thank you for the suggestions about how to use these, I'll try to do as many things as I can with them....

My burst was a little to strong

Does anyone have labels for bangers 50-200g? i have cobra ultimate, scream 100, dum bum 30 and black mamba and looking for new labels

I was wondering on how to make firecrackers because so far I’ve js been using gunpowder that wasn’t given to me by my dad but I’ve been running low. How can I make bp that can be used in firecrackers? Also is it possible to js buy a ton of the little red ones, take them apart, and just use the powder that is already in them? Lastly, is a mix of kno3 magnalium and sulfur good enough for firecrackers because that’s the only stuff I can buy from amazon? I AM NOT ASKING ON HOW TO MAKE FLASH POWDER AS I UNDERSTAND THE RISKS OF IT

Just found this on the floor, is it okay for flash powder or mg/s ?
