Miech Posted June 30, 2009 Share Posted June 30, 2009 I like 20 and 26 the most I think. Number 39J never worked for me at all, it just was a coarse streamer without any glitter at all. Link to comment Share on other sites More sharing options...
TheSidewinder Posted June 30, 2009 Share Posted June 30, 2009 @Frank: Oh, ok, I see what he meant now. Yeah, with 40 to choose from, nearly everyone will have their own list of "favorites". Link to comment Share on other sites More sharing options...
Mumbles Posted July 1, 2009 Author Share Posted July 1, 2009 Did you use the 39J formula from this thread? It might be because it had an extra 5% BaCO3, which I have just now removed. Link to comment Share on other sites More sharing options...
Miech Posted July 1, 2009 Share Posted July 1, 2009 I got the formula from here, which is including 5% barium carbonate. I milled it for half an hour, excluding magnalium, aluminium and antimony trisulfide. From what I remember I pumped it with about 8% of water.

FrankRizzo Posted July 1, 2009 Share Posted July 1, 2009 Miech, Glitter mixes should not be milled, it ruins the effect. Link to comment Share on other sites More sharing options...
TheSidewinder Posted July 2, 2009 Share Posted July 2, 2009 I must be blind. Where is the "J" variant of #39 listed in this thread? Link to comment Share on other sites More sharing options...
Mumbles Posted July 2, 2009 Author Share Posted July 2, 2009 It's not labeled as such, but it's #40 here. The real number 40 exists, but is actually kind of rare to see for whatever reason. I couldn't find my copy of Pyrotechnica II when I went to look it up. Link to comment Share on other sites More sharing options...
flying fish Posted July 2, 2009 Share Posted July 2, 2009 (edited) I know there are some glitter formulas that only work "raw," but I'm not sure that's always the case. In fact, I mill most of my glitters briefly (an hour or less). It seems in my tests that the milling mostly effects the speed of the glitter and delay, and not whether or not it glitters. In some cases, milling would indeed speed up above the "glitter threshold" (making the delay effectively zero), or in some other way the milling may screw up the glitter chemistry. But I've milled win22, win39, and win19, and all of them glittered. Win19 WAS too fast to be effective, but it did glitter (also, my magnalium was likely too fine). The other two were of a desirable speed & glitter density. I think that any less milling and the stars would have suffered from fallout problems (which they already did to a small extent). Also, winokur's method (if I recall correctly) was something along the lines of mortar & pestling it REALLY well...which may be equivelent to a short time in a ball mill. It's not labeled as such, but it's #40 here. The real number 40 exists, but is actually kind of rare to see for whatever reason. I couldn't find my copy of Pyrotechnica II when I went to look it up. I have a photocopied reprint from skylighter (which I also can't find at the moment). Numbers 20 and 40 are cut off from the page. I wonder if that's the reason...

pyrogeorge Posted August 10, 2009 Share Posted August 10, 2009 what charcoal is ideal for this compositions?from softwood or hardwood? Link to comment Share on other sites More sharing options...
TheEskimo Posted August 10, 2009 Share Posted August 10, 2009 I don't think it really matters. I use crappy Skylighter airfloat, mainly 'cause I dont wanna waste my good homemade stuff on stars. My homemade stuff is for lift, and coating rice hulls. Link to comment Share on other sites More sharing options...
flying fish Posted August 10, 2009 Share Posted August 10, 2009 I've also used skylighter's hardwood airfloat, with good results. Willow and pine work too. The effects may vary to some extent, but generally glitters will function regaurdless of the charcoal source, unless perhaps it is something really unusual...

stoffel Posted November 13, 2009 Share Posted November 13, 2009 (edited) could anyone here tell me which of the winokur mixes or any other composition comes close to this kind of glitter effect? http://www.youtube.com/watch?v=USzrkmeKdug...feature=channel we had this wonderful huge roman candle last year and i want to reproduce the effect btw this is my first post here, hello @ all!ive been reading for several years in this great forum and always had my questions answered.. but in this case im just missing the time and energy to test out all the comps that fit by description.. or in other words im too lazy to answer this question myself greetings, stoffel Edited November 13, 2009 by stoffel Link to comment Share on other sites More sharing options...
Ventsi Posted November 13, 2009 Share Posted November 13, 2009 Holy crap!! That was loud!!! To answer you Q'n:That as far as I see is NOT a glitter. It looks a lot more like a brocade formula with some spherical Ti, perhaps a delay agent. My money is on brocade using Sphere Ti though, and a SUPER hard break!

firetech Posted November 13, 2009 Share Posted November 13, 2009 I'm just taking a guess here...but I'm pretty sure thats not glitter. Maybe firefly Al or flitters...Looks to me like a simple streamer comp was used with just an added percentage of coarse Al. Link to comment Share on other sites More sharing options...
stoffel Posted November 13, 2009 Share Posted November 13, 2009 thanks for your suggestions.. i guess ill try some flitter comps then and see if i can get something like the desired effect by adding coarser metal.. the only spherical Ti i have is too fine i suppose, its only about 50micron, but i have granulate and flitter in 200-400micron.. lets see what that does Link to comment Share on other sites More sharing options...
FREAKYDUTCHMEN Posted November 13, 2009 Share Posted November 13, 2009 Could be ti sponge too. Link to comment Share on other sites More sharing options...
Seymour Posted November 13, 2009 Share Posted November 13, 2009 That as far as I see is NOT a glitter. It looks a lot more like a brocade formula with some spherical Ti, perhaps a delay agent. My money is on brocade using Sphere Ti though, and a SUPER hard break! I mostly agree, though there is no reason that it needs to be spherical. I have made a similar effect using coarse sponge. The key word being coarse. I used 20-40 mesh, I think. My formula was indeed a brocade type formula, indeed with a delay agent. 38% Charcoal35% Potassium nitrate13% Sulfur6% Titanium5% Binder3% Sodium bicarbonate As a binder I used Gum Arabic. if you also want to imitate that really hard burst, you will want to use it or another strong binder.

Ventsi Posted December 23, 2009 Share Posted December 23, 2009 I've heard yes and no, but can I cut glitter formulas? #26 on the list being my subject. I'm still waiting on my star plates from pianomiestro, only other way I thought I could quickly make 500g of glitter stars would be to hand roll the stars.?

Mumbles Posted December 23, 2009 Author Share Posted December 23, 2009 Sure you can cut it. I always use boric acid soln, but it's not usually necessary. Something to keep in mind is that cut, pumped, and rolled glitters will all have different effects. Link to comment Share on other sites More sharing options...
TheEskimo Posted December 23, 2009 Share Posted December 23, 2009 Could you explain as to why there would be different burning effects? Is a it a matter of different densities, and so burn speed is affected? Or is it more a matter of the amount of liquid used? PyroGuide (forgive me) says that excess water can ruin a glitter comp.

Ventsi Posted December 23, 2009 Share Posted December 23, 2009 (edited) Thats interesting, I noticed that when I over-wet half a batch for pumping, the wetter stars burned faster. In your experience,how do they differ? Just burn rates? Or does the effect completely differ from method to method. Edit: Garr, you got to it before me[well kind of].
