dynomike1 Posted August 12, 2013 Share Posted August 12, 2013 The other day i received some Barium nitrate, Strontium nitrate, and Potassium perchlorate, and they were lumpy. So one of them wound up in an unmarked bag, i thought what the hell i'll make some green or red stars. So after i made the comp i made a line and lit it, brightest white i have seen i mean blinding white, so i figure it was Potassium perchlorate. Here is the formula. I may try to roll some stars tomorrow. PP 50Mgal 18Parlon 16Red gum 10Dex 5 Link to comment Share on other sites More sharing options...
Sinken Posted August 14, 2013 Share Posted August 14, 2013 Do you have a video? How bright is it compared to simple white? Link to comment Share on other sites More sharing options...
dynomike1 Posted August 17, 2013 Author Share Posted August 17, 2013 This is the best i could get, no air stirring. This is a 1/2" pumped star. http://youtu.be/xksfwIFy-e8 Link to comment Share on other sites More sharing options...
FlaMtnBkr Posted August 22, 2013 Share Posted August 22, 2013 There is a fairly strong red tinge being reflected off the ground. The flame also doesn't look very white but more yellow or gold. I can't imagine strontium nitrate not being a strong red though. Maybe you can take some known SrNO3 and mix it up in the same formula and see how it burns just to double check. Or mix some of the unmarked bag with dark aluminum and see how good of a bang you get from a gram assuming you have experience with flash. Just a thought. Even the still image on the YouTube video shows the red at the 1-2 o'clock area. Link to comment Share on other sites More sharing options...
dynomike1 Posted August 22, 2013 Author Share Posted August 22, 2013 (edited) Even still it looks and works better than KN03 white.From where i was standing i haven't seen red or gold, these phone cameras seem to alter colors some. I'll try another one next time i get some air. Ok i went back and burnt some more and there is a little gold in it.I think those colors were coming from the smoke. Here is another video i just took. Star is from same batch. Edited August 23, 2013 by dynomike1 Link to comment Share on other sites More sharing options...
FlaMtnBkr Posted August 25, 2013 Share Posted August 25, 2013 Yeah I still see quite a bit of red in the reflection. Maybe the bright white is from the high metal content. I don't know, I was just pointing out what I saw. Link to comment Share on other sites More sharing options...
psyco_1322 Posted August 26, 2013 Share Posted August 26, 2013 If it was either Barium or Strontium nitrate, there would be an unmistakable color to the comp. It is definitely not either of those. It is possible to make white burning comps with barium nitrate though, but with the chlorine donor, it would be sure to come out sort of green. On the other hand, if only one was not marked, why could you not just read the other two and decipher what the mystery one was? Usually KClO4 will be free flowing and "dusty", if not, it's in hard, solid lumps. All the barium nitrate I have seen is sort of clumpy/crumbly (like feta cheese), and has almost a damp appearance.

taiwanluthiers Posted September 1, 2013 Share Posted September 1, 2013 Barium nitrate, without parlon makes exceptionally bright white light... something about the barium oxide formed causing it to be really bright. Parlon isn't necessary in any white formulation... Try Bleaser's #26 which is already very bright. It is a strobe star however so find something that contains barium nitrate and MgAl...

Mumbles Posted September 1, 2013 Share Posted September 1, 2013 You can definitively tell all three apart based on water solubility. They're about an order of magnitude different from each other. KClO4 - ~1.5g/100mLBa(NO3)2 - ~10g/100mLSr(NO3)2 - ~60g/100mL Link to comment Share on other sites More sharing options...
