dave321 Posted September 14, 2012 Share Posted September 14, 2012 just curious as to what maybe the "standard" air burst composition is? are companies using 70/30 with added aluminium flake ? one composition as quoted in the msds sheet by a swedish company is pot perc 50aluminium 25antimony trisulphide 25 obviously no mention of aluminium particle size in an msds but the above would appear perhaps somewhat uneccessarily hazardous with the antimony sulphide comments ? dave Link to comment Share on other sites More sharing options...
Arthur Posted September 14, 2012 Share Posted September 14, 2012 Don't be surprised if it's a nitrate flash. Remember that they want everything except bang from these. I'm guessing that the aluminium mesh sizes and their proportions are also important to the performance of the mix. Link to comment Share on other sites More sharing options...
dave321 Posted September 23, 2012 Author Share Posted September 23, 2012 actually, on a small scale, (200mg) the above compositionseems less pokey than std 70/30(probably do to the lower perc level and less aluminium) obviously still needs care though dave Link to comment Share on other sites More sharing options...
Bcorso85 Posted November 5, 2012 Share Posted November 5, 2012 The formula that the company uses is a toned down flash comp. Usually there's some titanium in it. The antinomy is added for more of a crack than a boom sound. number 5 concussions are all about noise. Honestly I don't think the 'authorities' know what one of those really is. Being the loudest indoor device, its an m-80. Aluminum particle size is always very small for the hotter burn. just a friendly reminder' no matter what the formula it is always dangerous.Im working on making my own 20 shot cakes. I may take the above mentioned comp into consideration for a break charge on a 1 x 2 1/2 inch insert. Link to comment Share on other sites More sharing options...
spitfire Posted November 16, 2012 Share Posted November 16, 2012 Maybe this will work for your purposes: KNO3 50Dark Al 30Sulfur 20 Fine flake can be used too, but less effective. Link to comment Share on other sites More sharing options...

All the stuff you guys have listed so far looks like a salute and not flame. -dag Link to comment Share on other sites More sharing options...
FlaMtnBkr Posted November 20, 2012 Share Posted November 20, 2012 I have heard of a theatrical flash that is, if I remember correctly, 50/50 strontium nitrate and magnesium. Might be worth looking into more. Link to comment Share on other sites More sharing options...
dagabu Posted November 20, 2012 Share Posted November 20, 2012 Our club does theatrical pyro (Proximate) all the time but only flash mugs on the ground are approved in a show here, no air-bursts. -dag Link to comment Share on other sites More sharing options...

The compositions above produce much smoke and is dangerous. The basic compositions is: Mg 400 mesh, strontium nitrate or Barium nitrate both 200 mesh , Ti 30 mesh or flake aluminium 40 mesh.
