Yankie Posted May 13, 2009 Share Posted May 13, 2009 Name of composition: Yankie's KP Purple Composition Type: Coloured star Creator: Yankie Color/Effect: Purple The Composition: (by weight) KClO4.........................50Parlon.........................15CuO............................12SrCO3...........................9Red Gum.......................8MgAl (325 mesh)............5 Make sure all chems are fine enough and screen them all together. Use acetone or alcohol as the solvent, or add 5% dextrin/SGRS and bind with water. Can be cut, pumped or rolled.A BP prime is all that is needed, however if you wish you can add a few % MgAl just to be sure In the video is a 1" starmine with some 10mm pumped stars, sprinkled with meal powder as I could not be arsed priming them at the time.

swervedriver Posted May 13, 2009 Share Posted May 13, 2009 Very nice KP purple! It really is like a barney purple, not to red and not to blue, just purple. Metal fueled too. Did you fire one hard in a star gun to see how it does in the wind? Link to comment Share on other sites More sharing options...

TYRONEEZEKIEL Posted May 15, 2009 Share Posted May 15, 2009 Why do you suggest using dextrin as binder? Parlon seems to do the job here, and water + magnesium tends to cause problems. But great star though! Link to comment Share on other sites More sharing options...

But great star though! I only suggest it as an alternative to those who are too stingy to use acetone. The star comp contains Magnelium (MgAl) not Magnesium (Mg), MgAl is much less reactive with water. Link to comment Share on other sites More sharing options...
TYRONEEZEKIEL Posted May 17, 2009 Share Posted May 17, 2009 Ah.. True words. I didnt catch that one. It is a great star man. I will use that for sure! Link to comment Share on other sites More sharing options...
Arthur Posted May 17, 2009 Share Posted May 17, 2009 With red gum, parlon and dextrin you could bind with water or alcohol or acetone! water leads to a star that may soften on damping but the solvent is cheap! acetone or meths cost money but the star product is more certainly hard amd damp proof.

Jwilson Posted May 21, 2009 Share Posted May 21, 2009 Tested this comp and I love it. My girlfriend called it Barney Purple and I now have it written down as Yankies Barney Purple. Pumped 17mm stars and tested out of a stargun. Love the colour and it lights easily. Thanks Yankie! Link to comment Share on other sites More sharing options...

FREAKYDUTCHMEN Posted May 21, 2009 Share Posted May 21, 2009 Looks quite a bit like the veline purple, definitely a nice purple! Link to comment Share on other sites More sharing options...
TYRONEEZEKIEL Posted May 22, 2009 Share Posted May 22, 2009 I made a 50g batch last night. They are beautiful! I added a bit of hexamine in too.. I love these stars! Link to comment Share on other sites More sharing options...
Bonny Posted June 9, 2009 Share Posted June 9, 2009 I made a small batch of these the other day and I really like the colour. I added 5% dextrin to bind with water. I haven't tested in the air, but they they took fire very easily with only a thin BP prime. Link to comment Share on other sites More sharing options...
pyrogeorge Posted June 11, 2009 Share Posted June 11, 2009 very nice purple! can i use pvc instead of parlon and shellac instead of red gum? Link to comment Share on other sites More sharing options...
Mumbles Posted June 11, 2009 Share Posted June 11, 2009 very nice purple! can i use pvc instead of parlon and shellac instead of red gum? Of course you can, but it will change the properties. It's hard to tell to what degree, or if they will be favorable or not though. Link to comment Share on other sites More sharing options...
pyrogeorge Posted June 12, 2009 Share Posted June 12, 2009 yes i will add 2-3% more pvc in formula Link to comment Share on other sites More sharing options...
TrueBluePyro Posted June 24, 2009 Share Posted June 24, 2009 (edited) OK, I want to make this shiss now, but I have one small prob...I have no MgAl, I am thinking that I could use just Al (atomized) I have dark and atomized Al, I will try using the atomzied Al as it is a way closer mesh then the dark and I have tried subbing MgAl with atomized Al before for a blue...so I will try it and burn a bit of the powder and tell you how it goes. I dont think I will try it with the dark Al as it would be a waste (not much, tho') and I dont think is as close to atomized. Soz, just kinda rambleling on here, but just letting you know what I'm trying....

Mumbles Posted June 24, 2009 Share Posted June 24, 2009 I find that an equivalent mesh flake is about equal to the corresponding mesh MgAl in terms of burn speed, ignitability, and color saturation. Link to comment Share on other sites More sharing options...
sparksnsky Posted June 25, 2009 Share Posted June 25, 2009 I tested this purple (original formula, not with Al). Its fantastic.The vid also contains a blue and a red star test. The statrs were not primed. Link to comment Share on other sites More sharing options...
Mumbles Posted June 26, 2009 Share Posted June 26, 2009 Hmmmmm. So TrueBlue, how much do you think Ventsi would appreciate you practically posting his formula verbatim on passfire as your own? Link to comment Share on other sites More sharing options...
TrueBluePyro Posted June 26, 2009 Share Posted June 26, 2009 I didnt, wtf has this got to do with this thread, send me a bloody PM. Link to comment Share on other sites More sharing options...
Mumbles Posted June 26, 2009 Share Posted June 26, 2009 If you're posting stuff in another public forum, so will I. The formula you posted is in parenthesis. KClO4.........................50 (49)Parlon.........................15 (14)CuO............................12 (12)SrCO3...........................9 (10)Red Gum.......................8 (10)MgAl (325 mesh)............5 (5) Link to comment Share on other sites More sharing options...
TrueBluePyro Posted June 26, 2009 Share Posted June 26, 2009 (edited) Exactly, it is an improvement and better and richer than the first (i'm sure it could still do some improving, I'm not saying it is perfect). It isnt the same, and thanks for posting it here, you should give it a go. I know what you are trying to prove, but you are wrong. Please PM me if you have any further problems. If the forum you are talking about is passfire, I wouldnt really consider that a public forum, as I have to pay for it.
