TYRONEEZEKIEL Posted January 17, 2009 Posted January 17, 2009 Well everyone, I was able to get a hold of a bunch of chemicals from a guy who got out of the hobby, and I have reached a dilemma... I have been unable to find a good comp that uses my chemicals. I have most everything except KClO4. Do you know what I could do with? CharcoalSulfurKNO3NH4ClO4BaNO3BaCO3SrNO3SrCO3CuO blackFeO red, black, and yellowAl (VERY LOW ON)Mg (EXTREEMELY LOW ON)ParlonCrO I think that is all I have at the moment.Anything would be great, thanks!
Mumbles Posted January 17, 2009 Posted January 17, 2009 You can make a few glitterrs, with your notably low Aluminum. Thats about all I can think of besides BP and the similar charcoal streamer mixes. You'd be in the clear with an organic fuel like Red gum, shellac, or rosin. Probably even hexamine. That is the main thing keeping you away from quite a few more colored stars. I've provided a few possible colored stars for you, as it seems this is what you were interest in. They're mostly modified by me to fit your chemicals, so they are no guarantees.

TYRONEEZEKIEL Posted January 17, 2009 Author Posted January 17, 2009 Thanks mumbles. I have made the first comp already, and I like it a lot. priming is a bit of a problem though. I am very interested to try the purple out. Thanks!
LGM Posted January 17, 2009 Posted January 17, 2009 Here's a white formula from creagan.net. I've had bad luck with it, but someone else on here discovered it on his own and had it work fine. Potassium nitrate 59%Sulfur 30%black powder 11% You might be able to get away using sugar as a fuel, I've had good luck with a 55% KClO3 20% Su, 25% SrCO3 red.
Seymour Posted January 24, 2009 Posted January 24, 2009 Seeing as you have Chrome oxide, you might want to use it to catalyze the AP stars. It will increase the burn rate, and make the stars combustion more stable at low pressures (like in the open air). Hopefully this translates to a greater resistance to the friction of the air "blowing out" the flame when it is traveling at a decent velocity. You could make some great Magnesium fueled reds and greens, if you can spare it. Something along the lines of Emerald green and Ruby red, slightly modified. Perhaps: Barium/Strontium nitrate 50%Parlon 20Magnesium 15Airfloat Charcoal 5Sulfur 5Dextrin 5 In this case the Dextrin is only as a fuel. Do not, unless you like wasting chemicals and making a foamy mess, use water as a solvent, unless your Mg is well coated. Use Parlon as the binder and use Acetone (preferably anhydrous) as a solvent. Even in this case, it might be wise to coat your Magnesium. LGM, those Sulfur whites, in my experience, take a long time to fully dry, and will not burn at any decent speed, and are hard to ignite until they are bone dry. This is made worse by the fact that for much of this time they appear dry. Perhaps this could explain your bad luck? Once they are indeed dry, I have found them to be fierce burning, and easy to ignite.
TYRONEEZEKIEL Posted January 28, 2009 Author Posted January 28, 2009 Would I just add the Chrome oxide to the ap stars in a +5% manner as I would iron oxide to BP? And for anhydrous acetone, you mean pure liquid acetone right?
Mumbles Posted January 28, 2009 Posted January 28, 2009 Anhydrous acetone means dry acetone. This generally involves storing it over molecular sieves, or adding some dry CaCl2 or CaSO4. As far as chromium oxide, I'm not sure. It should work, and +5% sounds about right. You'd want to adjust to to get an appropriate burn rate though.
qwezxc12 Posted January 28, 2009 Posted January 28, 2009 Are there other (common) metal oxides that catalyze AP-oxidized mixes? I wondered if the list of standard Whistle catalysts was a good place to start - Copper Oxychloride gave the best results on Danny Cregan's test list - wondering if it would make a good blue used in small % with the Copper Oxide AP blue I use (which burns quite slow)
Mumbles Posted January 28, 2009 Posted January 28, 2009 All of them, in theory, will catalyze AP. It's a fairly safe bet that if it catalyzes whistle, it will catalyze AP. In reality, it acts on the Perchlorate ion, and has little to do with the counter ion. There are of course base reactivity differences, but it should all work.
