KNO3 white

You can replace dextrin with SGRS without any problem.

Try TT+ 15% atomized aluminum or Hardt streamer composition also dont forget to use boric acid to prevent aluminum & nitrate reaction.

I've always found the KNO3 based white formulas a little hard to light, or at least stay lit. There is a difference between not lighting at all, and blowing out because they're traveling too fast. The end result is the same, but the solution is different.

 

Anything that ensures the cores light certainly isn't a waste. I'd rather go overboard and use up a little expensive metal than risk the cores lighting poorly. At 5% Al you'll barely use any anyway. Even with a kilo of stars using heavy priming, you'd be using at most about 10g of Al.

 

Dextrin and SGRS can be used interchangeably as a binder. They will have different working properties, but they're both proficient at binding in the same quantities.

I only have german dark aluminium at the moment.

I hope atleast you have Barium Nitrate in your hand.

Here is hardt bright streamer #2

Meal powder-67

Barium nitrate-9

dark aluminum-17

dex-7

Hardt bright streamer #3

KNO3-11

dark aluminum-17

meal powder-56

wheat flour-11

dex-5

add 2% boric acid in each formula.

 

Order some ferro titanium it will ignite most hard lit stars & also used to produce elegant streamer effect....

How big was this star?, and how fine the Mg?

5 mm. Mg 150 mesh.

Another composition. But less light. For stars of the shell.

 

KNO3 - 50%

Mg (150 mesh) - 30%

PVC - 20%

nitrocellulose - 8% (over 100%)

Who ever worked with compositions: KNO3+Sb2S3+S ?

 

I did with black Sb2S3. Composition did not work :unsure:

WOW! A Lot of great formulas to experiment with! Thanks Everyone.

I second that.

 

However, Mg is not an option for me. It is available, but so far I don't feel like I have the required workshop to store that..

I wonder if MgAl will perform as well, in these formulas.

Yes magnelium will work.

You may also use dark aluminum powder and magnelium together.

KNO3 45, Magnalium 200 mesh 20, Gd 10,

Sulpher 25 bind with Nc lacker.

 

Give a nice white star just as bright as the Mg
