Chandan123 Posted May 26 Posted May 26 Can anyone help me with this effect, hmm, what is called, and about composition? VID20250320002550.mp4
Zumber Posted May 26 Posted May 26 Local Name-velvet effect Pyrotechnic name-gold glitter with charcoal tail. Composition - already discussed several times here this year.
Norsepyro Posted May 26 Posted May 26 I think this looked more like a traditional fine grained glitter star without charcoal effect, but it is difficult to tell exactly from the video quality. Is is however not easy to get a dense long tailed and fine grained glitter from the traditional winokur type formulae, in my experience.

It has already been discussed that the problem is not able to create the effect and couldn't find any composition here; discuss only about this topic. The only composition is of pirotex, which includes nano3, which is highly hygroscopic and not recommended for longer storage.

Yes, I think it is something called twinkler, according to Ogley's theory. I had read the book, but it didn't give any insight into creating the twinkling effect.
Carbon796 Posted yesterday at 04:30 AM Posted yesterday at 04:30 AM Just pick one, of the two dozen or so common glitter/tremalon/flitter/twinkler/snowball formulas. That you like the description of. Or have the available ingredients for.

We are still working on it, I have already purchased that shell from company who make this effect, I have physically observed also did a burn test and I can say that it is atomized aluminum based not magnelium based. You have to test existing formulations of same effect till we proceed further.

Yes, I tested some formulas but didn't get the effect, and yes, u are right, it is about atomized al, but I think it is not 200 mesh. Zumber, if u get any insight about it, plz share if I will be able to create the effect. The previous formula I tested dried on the ground in powder; it burned like glitter, but the star did not give the effect. Thank you for the reply.
Norsepyro Posted 13 hours ago Posted 13 hours ago It would be very interesting to see if someone comes up with a working glittering formula based on atomized aluminium in a charcoal star. I think you need a composition which creates relatively large and long lasting fire dust grains ala firefly to achieve this. Also some lampblack 5-10% added to a ordinary charcoal star may achieve this. I have found these formulae based on fine Titanium to give a quite attractive golden glittering combined with charcoal effect: KNO3 : 46 Charcoal AF mixed: 26 Charcoal 80 mesh: 10.5 Lampblack: 5.5 Sulfur: 6 SGRS: 6 Titanium flake 60-100 mesh: 5.5 Also Tiger Tail with 5.5 parts lampblack substituted for 5.5 of the charcoal, and 5.5 parts 60-100 mesh Ti added works even nicer, with longer lasting tail. With 60-100 Ti flake the sparks are golden in these formulae with lampblack added, likely because of the lowered combustion temperature from lampblack. 60-120 mesh Ti sponge gives whiter flashes.
