Stef727 Posted December 18, 2015 Posted December 18, 2015 Does anyone know what composition is this star at 11shttps://youtu.be/gjUZGHNd8tw?t=11 Or if you guys know any similar comps??
lloyd Posted December 18, 2015 Posted December 18, 2015 It just looks like a pretty ordinary chlorate-based aluminum flitter. It's obviously heavy on the fairly large flake Al. But other than that, there's nothing really special about it. Lloyd

lloyd Posted December 19, 2015 Posted December 19, 2015 (edited) No, 70-mesh granular is far too coarse for a glitter or flitter comp. IF it's a white flitter, it likely uses a large flake. If it's a short-lived glitter, it likely is either fine flake or spheroidal. I use -325 mesh spheroidal aluminum in my Buttered Popcorn gold glitter. If you use perc, it'll burn a lot hotter than a chlorate base, and you might have to increase the aluminum particle size in order to avoid making the equivalent of coarse flash. To someone who said it looks like titanium... I don't think so, because of the long 'after-twinkle' that's so characteristic of aluminum comps. Lloyd Edited December 19, 2015 by lloyd 1

Lloyd I have all sizes of titanium and 200 mesh spherical Al Is there any comp that looks similar to what there is in the video with the stuff I have? Edited December 21, 2015 by Stef727
lloyd Posted December 21, 2015 Posted December 21, 2015 Stef,I don't believe it's titanium. Maybe. Try something, and see if you get that long-hanging 'twinkle' from it. I never have. It burns, then it goes out. Lloyd
Mumbles Posted December 23, 2015 Posted December 23, 2015 Lloyd, you can get something resembling the twinkling from titanium as well. Formulas like some brocades or Nishiki Kamuro have some of that same twinkling toward the end. It's not as good or long lived as the effect from coarse flitter aluminum, but it's there. My personal favorite brocade uses a mix of titanium and coarse flake aluminum. Are chlorate based streamers normally that coarse looking all the way through? The few I've made tend to be a lot more fine grained toward the head, and eventually fade out into the coarser and shimmering type tail. I suppose if they used much less bright flake or fine flitters that would give a coarser looking tail too. The coarseness of the tail might be why some think it could be at least partially titanium based. I can't tell if it's a camera issue, but it looks like there might be some charcoal in there as well. There's an orange tail that emerges after most of the aluminum burns away. Might be an artifact from the very bright initial effect.

Mumbles Posted January 3, 2016 Posted January 3, 2016 Withsayak, those are all white star formulas. If you take a look at the video, the stars in question are actually streamers. The formulas you copy and pasted off of the Wouter Visser website, or clone there of, will leave no tail.
Peret Posted January 5, 2016 Posted January 5, 2016 It looks more like Bleser Blonde Streamer to me. At 12 seconds it's gone quite golden. 45 KNO329 Air float Charcoal 6 Sulfur15 Ferrotitanium 5 Dextrin
