Wanted to create a strobe star using potassium nitrate instead of barium nitrate, because I was running out of barium nitrate.

The star strobes with a brilliant white color.

 

Name of composition: Red's Kno3 white strobe

 

Composition Type: Star formula

Creator: Redbullzuiper

Color/Effect: White strobe

 

Composition:

Kno3 ................ 60

Magnalium ................ 18 (70-100 mesh, video uses 70 mesh)

Sulfur ................ 19

PVB ................ 3

SGRS ................ 4 (or dextrin)

 

You can also leave out the sgrs and bind them witn PVB using 100% ipa.

 

Any Precautions/Incompatabilities:

Keep them free from moisture.

 

Precedure/Preparation:

Rol or pump, this I tested, I did not test cut stars but I bet that works just fine too.

The mesh size of the magnalium determines the strobe rate.

They light fairly easy, the star in the video is lighted with just a visco fuse wrapped around the star.

However, I do recommend to use a something hotter than a simple meal prime.

 

Star size in the video was 4mm and was pumped.

Currently around 500 stars are drying and will post a video of them in a shell when they are ready.

What is the role of PVB in this composition.?

 

Is it bright white flash in-person? Its look like white-ish gold.

The PVB slows the comp down, and whitens the flame.

 

There is no goldish color when you see in person, its just the camera (Galaxy S10+) that makes it looks that way. And probaly because the shed is build from wood and reflects the color onto the camera lense. Try out a bit loose powder on the ground, and you can see the color in person, just becarefull, if too close you will have a flame for the next 5 minutes in your retina :)

Looks promising but you should testing this composition in the air, in any case to see final result in air flow.
