baso112 Posted January 21, 2014 Posted January 21, 2014 I want to prime the kno3 white stars and then i wanna roll a streamer comp on the kno3 white
Zumber Posted January 21, 2014 Posted January 21, 2014 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.
baso112 Posted January 21, 2014 Posted January 21, 2014 I only have german dark aluminium at the moment.
Mumbles Posted January 21, 2014 Posted January 21, 2014 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.
Zumber Posted January 22, 2014 Posted January 22, 2014 I only have german dark aluminium at the moment.I hope atleast you have Barium Nitrate in your hand.Here is hardt bright streamer #2Meal powder-67Barium nitrate-9dark aluminum-17dex-7Hardt bright streamer #3KNO3-11dark aluminum-17meal powder-56wheat flour-11dex-5add 2% boric acid in each formula. Order some ferro titanium it will ignite most hard lit stars & also used to produce elegant streamer effect....
Niladmirari Posted January 22, 2014 Posted January 22, 2014 I experimented. My best composition: KNO3 - 45%Mg - 30%S - 25%K2Cr2O7 - 4% (over 100%)nitrocellulose - 8% (over 100%) I think the best white. http://youtu.be/fabDKJdJaeU
burningRNX Posted January 23, 2014 Posted January 23, 2014 How big was this star?, and how fine the Mg?
Niladmirari Posted January 25, 2014 Posted January 25, 2014 How big was this star?, and how fine the Mg?5 mm. Mg 150 mesh. 1
Niladmirari Posted March 1, 2014 Posted March 1, 2014 Another composition. But less light. For stars of the shell. KNO3 - 50%Mg (150 mesh) - 30%PVC - 20%nitrocellulose - 8% (over 100%) http://youtu.be/NeaMVuaRrV4
dynomike1 Posted March 3, 2014 Posted March 3, 2014 Heres one to try.KNO3 50Parlon 16Mgal18Red gum 10Dextrin 5 Dont know who created this one, but i fell out with it because it couldn't keep it burning.KNO3 59Sulfur 30Meal 11Dextrin 5
Niladmirari Posted March 3, 2014 Posted March 3, 2014 Who ever worked with compositions: KNO3+Sb2S3+S ? I did with black Sb2S3. Composition did not work
MWJ Posted May 24, 2014 Posted May 24, 2014 WOW! A Lot of great formulas to experiment with! Thanks Everyone.
Ubehage Posted April 27, 2015 Posted April 27, 2015 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.

pex Posted May 10, 2015 Posted May 10, 2015 (edited) 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 Edited May 10, 2015 by pex
