I gotta say, that comet was something! I've watched that vid more times than I'll admit. Thanks for sharing that. 👍👍

Beautiful! What size shell is this? 5inch?

Glad to see you here again..!!

I have only really used this forum for research for the past decade or so. This Forum has been a remarkable resource for my pyrotechnics adventures. I put the ball mill away about 5 years ago and mixed my first 10 lbs. this past weekend. Good to be back.

Is there any use at all for copper shavings and byproduct at all ?

It may still have a little moisture(the bigger sample) Yes I ball mill my BP very fine.

I’m a big fan of creating that “pause” between tail and burst as well. It looks so much cleaner to have the tail end before the break on rockets, shells with rising tails, bombettes, etc in my opinion. Straight BP works but burns fast… I’m thinking I might switch entirely to captive-visco clay bulkheads. No more fiddling with passfire holes, and a built-in delay between tail and burst!

Sorry firend i dont have any composition only know little chemistry behind perhaps you can try above mentioned compostion . Thank you enjoy and be safe.

It is dried well? Granules size varies according to purpose, do you ball mill your BP? Also just put a piece of visco or bm to save your hand getting burned when you lit.

No spam, Kindly discuss only Pyrotechnic activities here.

This is my first and second batches of Bp that I have granulated, one is not the cleanest burn. I feel that it is good enough for anything I’d put it up against I just like to share my progress. IMG_6313.MOV IMG_6312.MOV

In those countries where there are retail pyro chemical suppliers buy the chemicals from a known good supplier. If a chemical is not available then look for a way round that absence. In places where there is no retail supplier then you have to try to substitute chems from available sources, or do DIY manufacture. As a beginner it's unsafe to make random substitutions as there are some incompatibilities to avoid. Sometimes it's necessary to make your own chems but that adds extra risk and hazards to the hobby which you need to control carefully. Any experiments should start really small to minimise any harm.

Congratulations for successfully firing shell on first time, you can now improve step by step.

Yes sir , way to get around😁

Eh..the metal is of kinda limited use. But at the price of copper, sell 25 pounds and you can buy the better forms of it

I have availability to some copper scraps and was wondering if it can be abrasively removed into a powder or drilled to produce the byproduct shavings. Then, mix it into a star comp Copper, I've read, can produce blue flames, though I do not have copper chloride or copper carbonate, just plain copper If this is worth trying, I will incorporate it into my ariel shells.

Hello all, This is my first ariel shell success. I have finally done something right My decently hot, granulated BP is suitable for lifting my shells, as you see in the video The burst is BP layered with a sprinkle of flash for enhancement, and my "effect" is pieces of Visco cut up and placed on the walls of the shell. I also shot two others, one that did not have enough lift, and the other went cato in the pipe. I hope the video works. Here is the yt link-----

Thank you very much!! And thank you for encouraging everyone with your helpful attitude.

Nice rocket BengalFlair...!!

Honestly, my work is not so tight as yours I wouldn't notice the small 'defect'. Also, my shells are 4" at the smallest, so the effect wouldn't be as noticeableAs you suggested, a longer delay might help. One thing I like to do is to use straight BP in the last increment so the tail from the delay fades before the burst. So many nice burst pictures an videos have a big streak through them from the rocket tail. For the nozzled BP motors I guess plain scratch mix would be better as the last increment. Just spit-balling here. I should be asking how that one was made

Thanks! Any tips for making them even better? I’m thinking of trying a win 39J delay… this one had a variation of the Westech Roman candle delay, which has good length and hang but is rather dim.

Please swimming red composition please sir

That was a very nice rocket and shell!
