This comp is amazing to say the least.
Mixing it was wild, I haven't done anything that exhilarating in a while.
Between dealing with its sensitivity and making sure none got on or in me the whole process took at least two hours.
I tried two comps, the first was definitely inferior
so I settled with this:
Pb304 70
Black CuO 12.5
Mg/Al 17.5
Al 200m(atom +5
The first batch I tried was screened and was rather week. After switching to the above comp I also switched to cutting. The end product was cubes that ranged from 2-4mm3.
When I lit one of these to test them, Ignition took a moment but when it finally went, this thing didn't crackle or pop, it exploded! does anyone know the chemistry of this comp?
I could tell by the red mark left in the middle of the blast burn and the equally loud pop from cubes half as small, that my bigger cubes weren't fully reacting(not sure of the right term)?
so I primed them my bigger cubes with this:
Micro star prime Best of AFN III
Kn03 57.4
c 11.4
s 11.4
Al(dark) 5.7
silicon 11.4
dextrin 2.9
I didn't have silicon but something I had been planing on trying was filings pulled from dirt with a magnet. Previously I tried these for spark effects but they only molted up and glowed for a while. this is the purpose silicon serves in this prime, so I thought id give it a go. Like I said I have never used silicon nor did I try plain meal but this worked fine for this purpose.
The primed eggs going off sounded more like a salute than anything else. After the prime burned up and stopped glowing the egg began to glow then BOOM!
I screened and granulated some of this comp and put some in my newly acquired glitter and pressed some comets. For my primed eggs, I rolled a few in some extra firefly comp I had, and plan to shoot them in a mine once dry.
This is some interesting stuff, so many applications.
When they dry, I will post results of crackling comets and exploding firefly stars.
