Local Name-velvet effect 

Pyrotechnic name-gold glitter with charcoal tail.

Composition - already discussed several times here this year.

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.

Yes, I know Zumber. 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.

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.

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.
