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.

Blowing shit up is not a goal in itself. Seeing your device working the way you intended, is the greatest satisfaction of all.

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 :)
