firetech Posted January 5, 2009 Posted January 5, 2009 I was experimenting with the ratios for charcoal stars and came up with a great formula. 95...........KNO344...........Airfloat Charcoal15...........Sulfur10...........DextrinIt burns pretty fast with a pink/white tip and works great with a regular bp break.Try it out and tell me what you think!
psyco_1322 Posted January 5, 2009 Posted January 5, 2009 (edited) We have a compositions area for all your needs. Please post there next time. You can still slip it into a post in the aerial shell thread to give us a heads up though. This will likely get moved just to let you know. I'll give it a try and report back in about a week. Thanks.

firetech Posted January 5, 2009 Author Posted January 5, 2009 Oh great thanks! Well anyone who can move this please move it! ill search around for that section. Thanks
tentacles Posted January 6, 2009 Posted January 6, 2009 Here's the formula (withing a couple tenths) in parts per 100: KNO3 58C 27S 9Dex 6 Look forward to seeing the tests - this star is fairly similar to C6.
qwezxc12 Posted January 6, 2009 Posted January 6, 2009 ...this star is fairly similar to C6. C4.65 to be exact (if you follow Shimizu's ratio naming convention)
firetech Posted January 7, 2009 Author Posted January 7, 2009 The difference between the two, My star and C6 is that my star burns very fast and bright along with a pink/white tip.
Mumbles Posted January 7, 2009 Posted January 7, 2009 The lower the C#, the faster it burns. It's pretty similar to a spider star I make. Beautiful star. Very bushy, thick solid tail. No pink or white head though. KNO3 - 15 (53.6)C - 9 (32.1)S - 2 (7.1)Dex - 2 (7.1)
Mumbles Posted January 7, 2009 Posted January 7, 2009 Yeah, I think it's ofca. He had an article published on 4" spider shells in the first pyro book I ever got, Best of AFN 3. So, I of course had to make them. I broke a 2" canister shell with 5g of flash, and they lit just fine, no prime at all. Ah, those were the days, when I didn't even have to try priming anything. I've been using another spider star lately from Mike Swisher. It doesn't burn quite as fast, and it gives that nice creamy thick tail I love. Plus I don't have to ball mill it.

I will try it. Was it Ball Milled or grinded in anyway?
firetech Posted January 10, 2009 Author Posted January 10, 2009 Yes it was milled for about 3 hours. Before you press roll cut etc your stars just test the powder and it should burn with a big pink flame and lots of sparks.
firetech Posted January 12, 2009 Author Posted January 12, 2009 Skylighter airfloat. It is made from mixed hardwoods. Any charc should do fine as long as it is airfloat. I assume using a lighter wood like balsa would produce a faster burning comp.
psyco_1322 Posted May 11, 2009 Posted May 11, 2009 A 3" plastic ball with some cut ~3/8" pink headed spiders. I like it. http://i108.photobucket.com/albums/n3/psyco_1322/th_S4024759.jpg
