MDH Posted July 10, 2018 Share Posted July 10, 2018 (edited) Standard 75/15/10 black powder, -120 mesh aluminum. Add 1-2% coarser mesh (40-60) Ti for longer tail but more expense. Add 1%/W dextrin to bind. Just roll it like regular stars. Edited July 10, 2018 by MDH Link to comment Share on other sites More sharing options...

Mumbles Posted July 11, 2018 Share Posted July 11, 2018 Most of the Hardt silver streamers are hard to beat too. The chlorate based one is probably the fastest. Link to comment Share on other sites More sharing options...
robbo Posted July 11, 2018 Share Posted July 11, 2018 I like 50:50 bright flake Al + KClO4 for simplicity, plus 5% dextrin, but you MUST cut with additional wheat paste and really mix well (mush them in a plastic bag for small batches) or the material won't handle at all. I add enough thick wheat paste to make a squishy firm dough. Cut or pumped pretty large (3/4" minimum) and dusted with a scratch prime as you form them so the prime is mushed into the textured star surface. This is a basic Shimizu formula; you can depart from it (60/40 etc) and get different tail lengths and densities. They can swim! Performance all depends on your aluminum. Cheapest greasy paint-grade flake for the bulk of the Al works fine for me. They take a long time to dry and end up rather light in density. As you add more Al they burn more slowly and you lose the swimming and you lose some white/brightness, so I go with the 50/50 ratio and substitute in coarser flake for some of the Al portion for added tail length if I want. It is a very easy system to tune for your particular Al flake since it basically only has 2 components. Keep in mind that "silver streamer" (vs gold) needs the high burn temp of a chlorate or perchlorate system. BP (or KNO3) systems usually don't burn hot enough to get a "white" color temp. Black body radiation and all that. That's why Shimizu calls the KNO3/Al "golden waves" and the KClO4/Al system "silver waves". And I cannot imagine rolling this... has anybody rolled "silver waves"?

braddsn Posted July 14, 2018 Share Posted July 14, 2018 Bleser blonde streamer. But instead of using FeTi, use straight Ti. It burns very fast and bright. It's my go to for a fast silver streamer. 1 Link to comment Share on other sites More sharing options...
