pyrojig Posted November 7, 2021 Posted November 7, 2021 I have in past disassembled a commercial areal 2.5" salute shell . Interesting assembly and simple method used. The time fuse heavily primed in NC/bp slurry 2.5 sec. Delay. Into a shell with what appears to be seed or a type of rice hulls coated with a comp. Which I assume is perchlorate, charcoal, and metal (either ti of al. Fine maybe 100mesh or a tad coarser ) Like bp hulls with fine metal 5-10%ish of comp. This takes up half of the shell as a filler. The other half is obviously flash powder in a folded rice paper bag( to separate it from mingling with the hulls)The effect is a short spark effect similar to just adding large grapenuts ti sponge to a areal flash salute. .. just a interesting tid bit i thought would be interesting to share . If anyone has any idea of what they use (comp) to coat the hulls with , please share. It would be nice to find a spark producer for areal effects v.s. large ti sponge (expensive).
