dangerousamateur Posted February 28, 2014 Posted February 28, 2014 If you look at the spanish pdf and also at the rubber rainbow article from skylighter, you will find white/silver formulas that have chlorine donors in them.OK, some are parlon bound, but the spanish blanco brilliante is dextrine bound. What's the chlorine for? Why not use some cheaper fuel without chlorine? Or is the chlorine needed to shift the potassium ect. spectra into the visible range, something like that?
AzoMittle Posted March 1, 2014 Posted March 1, 2014 It would help me understand if you could please provide a link or copy the formulas to here?
dangerousamateur Posted March 1, 2014 Author Posted March 1, 2014 (edited) Sure:http://de.scribd.com/doc/70688538/Formulas-Color-y-Tecnica-Empav-1Look for blanco brilliante. And here look for Gary Smiths silver star:http://www.skylighter.com/fireworks/how-to-make/colored-screen-sliced-rubber-stars.asp Edited March 1, 2014 by dangerousamateur
Niladmirari Posted March 1, 2014 Posted March 1, 2014 (edited) I think parlon need because he participates in the reaction burning. Helps burning. MgAl + (C4H6Cl2)n = MgCl2 + AlCl3 + ... + heat (energy, luminosity) The reaction generates heat that goes into maintaining the burning. And more white light, more luminosity.

dangerousamateur Posted March 1, 2014 Author Posted March 1, 2014 Ok, but how about Al2O3 and MgO, cant they do the job as good?
Mumbles Posted March 1, 2014 Posted March 1, 2014 I think parlon need because he participates in the reaction burning. Helps burning.

Wow, you're really just bad at science. Might I suggest you stop spouting off incorrect bullshit. Magnesium Chloride and Aluminum Chloride are not white body emitter, and generally don't produce much white light. This is why most metal fueled colored stars have more chlorine donor in them to intentionally produce these species. MgO and Al2O3 produce copious amounts of white light, and you want to avoid them as much as possible. As far as why white stars have chlorine donors in them, no clue. There is the binder situation, but more than likely it's in there to be consistent with other formulas in the set than for any practical reason. It may also just temper the intensity of the white light to make it compatible with other stars. By the way, here's the spanish pdf without the need to pay for anything or go through any sketchy sources: http://www.amateurpyro.com/forums/topic/6544-formulas-priming-and-technical-pyrotechnics/
Niladmirari Posted March 1, 2014 Posted March 1, 2014 It was just a guess. Reaction of magnesium and teflon = MgF2 + white light: http://www.youtube.com/watch?v=QeqXld34zzQ
