FlaMtnBkr Posted June 12, 2014 Posted June 12, 2014 Just a dumb acronym meaning "insane black powder". It's basically black powder and flash.Mind sharing the formula and some construction info? Those do take off like a bullet. Is it basically BP with dark aluminum added?
boostedmx3 Posted June 12, 2014 Author Posted June 12, 2014 made my first batch of 50/50 kno3 and sugar mixed up a pound of each.. not quite as thick as i would like and burned a lil fast but it worked.. next batch will get some baking soda added to slow it down a bit.. any tips on making the smoke thicker?

FlaMtnBkr Posted June 12, 2014 Posted June 12, 2014 Thanks! Boosted, try adding wax to the mix to get it thicker. Somehow it got the name legendary smoke mix if you want to look up the ratios. You can also try adding a central core and even some narrower cores around the central core. This will get more of the comp burnt in less amount of time. So it makes the smoke thicker because it's pumping out the smoke faster.

Fla, http://www.amateurpyro.com/forums/topic/679-please-post-videos-if-you-got-em/?p=119821 no problem.. been on the forums for a long time with cars and what not.

I prepared the tubes before hand by pounding some bent. in the bottom. after filling them each up i put fuses in, half red visco and half green crackling fish fuse. after inserting the fuse most of them sank in a lil and i was able to top off with more comp. still waiting on them to fully dry as the one i lit was about 30 min after i made it and it was still wet also what do you mean by adding a core?? have a link or what should i search?

boostedmx3 Posted June 14, 2014 Author Posted June 14, 2014 just made my first batch of BP.. used pyrochem source sulfur and charcoal and the KNO3 came from a forum member. weighed it all.. mixed in a tub and through a food strainer from walmart a few times.. i then added a lil dextrin and water to get it to bind.. i think i may have made it too wet as it was hard to then screen will it be ok if i just let it dry?? its still clumpy just a lil glistining
BurritoBandito Posted June 14, 2014 Posted June 14, 2014 You may need to remill it and granulate it again. The problem is when the water evaporates away you're going to be left with recrystalized KNO3. Try to just add enough water to where it will form a coherent mass when squeezed. Add water in very small increments till you get the right consistency.
boostedmx3 Posted June 14, 2014 Author Posted June 14, 2014 (edited) it was def. holding together as a ball.. but when i squeezed it through the screen it was more sticking to it like mud then pushing through it.. just did a couple test burns.. i let my BP dry overnight first put a tiny bit of BP from a wolf pack commercial shell - this went poof real quick and gone then approx the same amount of my fine BP -approx the size of my kno3 - this stuff burned popped/sparked more then anything and one of the bigger nuggets that clumped up after screening. - about 1/8" in diamater - this peice lit and burned for a second or two both my BP's left some slag looking stuff in the metal bottle cap i was using to light them in Edited June 14, 2014 by boostedmx3
FlaMtnBkr Posted June 14, 2014 Posted June 14, 2014 (edited) It sounds like you didn't ball mill it. BP is fairly slow if not milled, especially if the chems are not very fine and not screened a couple times. The "BP" I made as a kid with BBQ charcoal barely burned at all. If you follow a good tutorial or read a bunch of threads, use a ball mill, and good hot charcoal, then it is fairly easy to make BP that is faster than the commercial stuff. Just follow the advise given in the many threads here and you will have some good stuff. But if trying without a mill or good charcoal then you will likely only end up disappointed. Edit: a core is a hole basically. It increases the surface area so more can burn at the same time. Edited June 14, 2014 by FlaMtnBkr
Mumbles Posted June 14, 2014 Posted June 14, 2014 What you have made is called polverone. It's granulated, un-milled, powder. Basically it's a flammable filler, but little more under most normal circumstances. Also, the generic charcoal from most pyro suppliers is going to be crap as far as speed goes. If you want to make BP capable of lifting or breaking shells, you'll need to mill the mixture and use a different charcoal.
boostedmx3 Posted June 15, 2014 Author Posted June 15, 2014 ya i keep hearing this mill stuff lol.. i guess i cant take any shortcuts.. and this will have to do for fountain stuff.. i mixed the hell out of it tho thought i would get a lil better result then i did
BurritoBandito Posted June 15, 2014 Posted June 15, 2014 You'd be surprised how big of a difference milling makes. It doesn't just mix the components up, but actually grinds them together resulting in a much more intimate mixture. I'd invest in a cheap rock tumbler I'd I were you. It's not a luxury for pyro, it's a necessity.
nater Posted June 15, 2014 Posted June 15, 2014 Slow BP will do just fine in a fountain with a little (15-20%) metal added for effect.
BurritoBandito Posted June 15, 2014 Posted June 15, 2014 Yes, Nater it will. I hope my last message didn't read as me saying it won't. Greenmix is fine for making gerbs, but for making good BP a ballmill is a must. Currently, the Harbor Freight Dual Drum Rotary Rock Tumbler is on sale link. It is a 6 lb tumbler, and is only 54 bucks right now.

Doing things the right way might seem tedious, but it will help you immensely. When you actually know what you're doing, then you can see if shortcuts will be okay.
boostedmx3 Posted June 22, 2014 Author Posted June 22, 2014 (edited) Used my first batch of weak home made BP about 3 grams and made a fish mine out of it.. Well I tried. Last week I took the BP from a shell that had the fuse fall out last year packed the BP in the bottom and put a bunch of lil fish fuse prices on top with a small piece of tissue paper between them. Then put more paper on top.. That worked pretty fricken awesome for what it was.. This one not so much did the same thing as last time Cept with my BP.. Well it was more like a fountain then a mine and none of the fish fuse even lit.. I has even primed them this time in the same BP I was using to lift. Except the BP shot the tissue paper and fuse out without lighting a single one WTH.. I guess it's just not hot enough.. However I still got a nice 10ft high shower of sparks Trying to upload a video from my iphone5s idk if it's working or not Edited June 22, 2014 by boostedmx3
