Zumber Posted September 13, 2010 Posted September 13, 2010 Red firework star- Note-all parts by weight only Strontium Nitrate........4 Potassium nitrate........2 Red gum.........1 Charcoal (air)........1/4 Note-star burns slowly but gives pretty red colour. size of star should be 5mm 1
Karlos Posted September 16, 2010 Posted September 16, 2010 What? Where is chlorine donor? This composition have zero value.
Updup Posted September 23, 2010 Posted September 23, 2010 Hmm, odd... Can you post a video of the stars? Or anyone with these chems want to give it a go? Sounds like it COULD work. Heh, it sounds a bit like if you don't have charcoal you can use air . In any case, red is going to be my next color, anyone have good suggestions? Red seems to be the next most basic star from D1
dagabu Posted September 23, 2010 Posted September 23, 2010 What? Where is chlorine donor? This composition have zero value. I agree, I just swept through the formulas at PF and see no reds with the same chems that don't have parlon.

Updup Posted September 23, 2010 Posted September 23, 2010 I agree, I just swept through the formulas at PF and see no reds with the same chems that don't have parlon. Alright. What about a KCLO3, Strontium carbanate/nitrate, red gum, ish comp?
dagabu Posted September 23, 2010 Posted September 23, 2010 Same problem, nothing to make the red, uh... red! You need Saran, Parlon, or (maybe) PVC to get the chlorine you need to improve the color.

It's True Blue's comp, I love it and it is my favorite to play with. I have three different meshed of Mg/Al that I substitute for the Al and it does wonderful things to the light output. If the rain stops soon, I will launch a rocket with my red star to report that I am working on.

dagabu Posted September 24, 2010 Posted September 24, 2010 Be sure and film your rocket for us! I always do but only share the ones that work. -or- CATO impressively!

NightHawkInLight Posted September 24, 2010 Posted September 24, 2010 I would like some opinions on something that came up during a short project of mine quite a while back now. A very obvious red was created with the following composition: Potassium Nitrate - 6Granular Magnesium - 4Charcoal - 1+ 1 marshmallow per 10g Skyisthelimit got it on camera a little better than I did, so here is his video:http://www.youtube.com/watch?v=ChA9NpJqmIA I double checked the ingredients to the marshmallows, there were no strontium compounds or anything else that might produce a red color. What do you think could cause this? I know that potassium metal burns purple, but it is not possible to tap into that color in any traditional compositions that I know of.
Seymour Posted September 24, 2010 Posted September 24, 2010 Well made Potassium nitrate/Sugar compositions burn a pretty good lilac, which matches the colour seen in the composition you showed fairly well. While I would not have expected it to show the K colour that well, it's still my best guess.
Mumbles Posted September 25, 2010 Posted September 25, 2010 My best guess would be the incandescence of the carbon particles. Perhaps the orange/yellow of the carbon interacting with the potassium lilac is giving the red.
Potassiumchlorate Posted June 29, 2012 Posted June 29, 2012 Try potassium chlorate+potassium benzoate 70:30. The colour is surprisingly towards the red - purple or magenta, I'd say. It might be that both are potassium salts and that potassium chlorate is a decent chlorine donor on its own.
Mumbles Posted June 30, 2012 Posted June 30, 2012 Potassium purples do not show up at a distance, and I'd be wary about making chlorate whistle. It's way too sensitive for my tastes.
burningRNX Posted January 25, 2015 Posted January 25, 2015 I think yes, with alcohol. But why this one?, there isn't much red collor I supose, did you try a litlle loose composition? did you like the collor of it?
