Effect name

Hello everyone.
Someone could help me to find out the effect name in the following video? The effect happens at minute 1.27 I always thought this effect was very beautiful, but I never saw the formula to accomplish it. It looks like a mixture of C8 with TI or very thin FETI, or it could also be AL. But I let the most experienced say something :D Thank you very much (google translator)

To my experience, it looks like a charcoal streamer with an added small particle sized metal, maybe FeTi or even plain Fe. I could be totally wrong, though.

Thanks for the answers.
At Zink Fireworks it's called silver. Here is another video, with comet of the same effect. It appears to have large metal particles.

That sizzle in the second video makes me think it has some coarse mgal in there. Possibly a mix with feti and coarse charcoal.

That is definitely a dragon's egg matrix comet in the first video. The second looks to also be a matrix comet with an unknown comp, a bit more reactive than what you'd expect from just large MgAl.

There are a lot of good suggestions in here. To me, it looks a little like an attempt to make a breaking glass comet. A firefly composition with titanium or coarser aluminum or MgAl would be a decent place to start. I'm not sure about the dragon eggs thing. There's definitely some sound, but I don't know if it's loud enough to really be DE's. I bet it'd still make a great effect even if it isn't exactly like the video though.

Thanks for the answers and suggestions. It doesn't sound like much DEs to me the sound that comes from seems to be more than MgAl. And if we join BP and MgAl wide we will hear that crackling sound. Some time ago I made similar effects together with Tiger Tail with some metals and the most similar to the effect of the videos was with Al and MgAl. But there is nothing like trying :D

I wonder how they are getting them so high? I shot a 2"last night and broke in 20 pieces.

Hi, jp190. Usualy, it call glittering willow comets. Basicaly it is matrix comets. Base is TT or C6 composition, and microstars are grains with size of 1-2 mm. You can try to use for this purpose nitrate based strobe composition. Simple white consist of 65% Ba(NO3)2 and 35% magnalium. If you subsitute Ba(NO3)2 by Sr(NO3)2 and add 5% parlon, redish glittering flashes can be obtained. For yellow color add 5% Na2C2O4 or Na3AlF6. I have tried ones to make such stars. See here some examples.

Thanks for the reply. But if I want a more consistent kamuro effect in the comet, do I have to make the kamuro composition and then put the microstars composition?

Sorry if I look a little dumb, but I am new to this. I always loved fireworks, but don't know much about stars compositions. I am a 1st year chemistry student, I know the basics (reactions, mechanisms of chemistries reactions) but in college, as obvious, we don't talk about fireworks.

It will be not spectacular. Kamuro comp has 25% FeTi and gives bright tail, it will overlight (overshine) microstars.
