What is the name of this effect?

Hello everyone, I would like you to help me discover the effect of aerial shells at minute 5.40. This pyrotechnics usually uses this effect a lot, both in aerial shells as well as in comets. I do not know if it's a kind of glitter or some flitter with a specific type of aluminum. Best Regards (I used google translator)

Best guess would be a silver palm or silver willow type star.

 

Some use all spherical aluminum, flake aluminum, granular titanium, spherical titanium, a combination of any of these, and either nitrate or perchlorate oxidizer, or both.

Whatever you try, make sure you have a good hot prime. Some of these might not light very easily.

Thanks a lot for the help :D I'll try some of these, I've already seen similar formulas used by "pirotex" and "piroQuake" as the name D1 mod, but I never saw the formula. The worst of it is that I do not have access to perchlorate, but I'll try kno3.

No problem, hopefully you can figure out how flake aluminum works in these as I don't have any 809 or the likes.

 

KNO3 can still give you a satisfactory effect, it just may have a touch of gold or yellow to the color compared to a perchlorate based variation.

 

The good news is that nitrate versions tend to be little easier to light. Good luck!

It looks a little bit like a breaking glass comet or a little bit like a high metal firefly. In any case, I would expect the metal in those streamers is quite coarse. You need something pretty big to get that sort of impressive hangtime. I'd venture a guess there is a considerable amount of metal coarser than 50 mesh. Eckhart makes a product called 41813 that is a pretty coarse flake Al. Transmet makes a very coarse material, K-101 or K-102, that is a bit thicker of a flake. Those might be what I'd start with. The effect is a bit far away to get a really good idea of what sort of formula they use or what the metal/particle shape is exactly. Coarse atomized Al or sponge Ti might also work.

Many thanks Mumbles, at first glance the effect seems to be some coarse aluminum, with a large retardant. I have aluminum flake 44μm and 250-650μm and also sawing filings. In my opinion the titanium can not be, I think it is a very silvery color for titanium, but I am no expert to state this. In some videos I've seen appear effects appear, I'll leave them in case anyone is interested. Thank you one more time.
