Strobe stars

[pirotek]

One more strobe star

possibly with a crimson color of flares

NH4ClO4 - 60%

Li2SO4 - 17%

MgAl - 23%

binding dextrin ~ 3%

Piro, have you seen Kaj Fredriksson's experiments with nitrate strobes on FW.com?

[pirotek]

no, I have not seen

[Yus]

Homemade shimmering and strobing stars based on Ba/Sr nitrate and bismuth oxide systems.

Yus, amazing! Would you be so kind to share the composition, especially the third white one? Is it the one given by pirotek yesterday?

[Yus]

Ba(NO3)2 - 68%, AlMg - 26%, Bi2O3 - 3%, binder - 3%.

[Sulphurstan]

👍 Thank you!

[Ubehage]

#3 MgAl typically isn't coated with anything. For magnesium, linseed oil or dichromate should both work.

Just be aware that dichromate is the closest thing you come to actual death while making pyro.

It's carcinogenic as f***.

 

Sorry! I didn't check the date before replying.

Wear gloves, wash your hands and don't eat the orange powder. I actually keep an excess in distilled water and just use it for wetting comps that need it so I don't have to mess with a respirator while dealing with it.

[Sulphurstan]

Ba(NO3)2 - 68%, AlMg - 26%, Bi2O3 - 3%, binder - 3%.

I just tested a star on the ground, and it looks very promising!!! Will fill a rocket head with 5 mm cuts and hopefully enjoy this (for me) new composition. Thanx again Yus 😀😊

What is mesh size of mgal works good in this composition.

Thanks

Wear gloves, wash your hands and don't eat the orange powder.

 

That made me think of a friend who keeps saying "eat the yellow snow, it might be beer" for some reason.

Sorry, quite off-topic.

[Yus]

sumagg27, mix 100-200 mesh

[sumagg27]

Thanks Mr.Yus

[pirotek]

Finally, I tested the Chinese strobe in the sky

[Yus]

Any ideas on reddish glittering/strobing comets?

Pyrotek, how big were those stars and which prime did you use?

[pirotek]

cubes 5х5 mm
prime (that red layer in the photo)
KNO3 - 70
phenolic resin - 22
Fe2O3 - 8
С - 2

and BP from the top

[Ubehage]

cubes 5х5 mm

prime (that red layer in the photo)

KNO3 - 70

phenolic resin - 22

Fe2O3 - 8

С - 2

 

How does that prime work? My first thought is that it needs more fuel, so I'm genuinely asking

[pirotek]

there is enough fuel,

try it

[burningRNX]

Pirotek

 

Did you use the monohydrate form of lithium sulphate in the red/pink strobe?

And what size MgAl?

[pirotek]

lithium sulphate is marked as anhydrous
magnalium marked as 80 μm

[Sulphurstan]

Yus,

In the bi2o3 strobe star system, do you think, we could make a blue one?

Have you made some experimentation to get it blue?

Mixing in copper compounds (copper benzo, cuo, cuco3...)

[Yus]

Sulphurstan. I've tried. But it does'n work.

Bi2O3 apakah bisa di ganti dengan kimia lain. Soal nya dsni gak ada kosong tolong balas
