mudmanc5 Posted October 22, 2008 Share Posted October 22, 2008 I have some 150-350 mesh spherical Ti and cant seem to find a good Comp. to use it in . All ideas welcome. Link to comment Share on other sites More sharing options...
FREAKYDUTCHMEN Posted October 22, 2008 Share Posted October 22, 2008 Simply ad about 10 to 20% to your willow comp. Link to comment Share on other sites More sharing options...

Miech Posted October 22, 2008 Share Posted October 22, 2008 That was exactly what I was going to say, it gives a really nice sort of glitter. It might even be one of the best glitters I've ever seen. I used 250-350 um (something like 80 mesh by head) spherical titanium and Chrysanthemum 8 with pine charcoal. It might not exactly be a glitter seen from chemical point of view, but it looks very much like it though. It is way easier to process when the titanium is added after wetting the composition. Titanium has a strong tendency to end up in the bottom of the jar containing the composition. Link to comment Share on other sites More sharing options...
tentacles Posted October 23, 2008 Share Posted October 23, 2008 (edited) There's also Buell Slow Gold, here's a video of some I made recently with 20-80 mesh sponge Ti. You could probably sub in a courser sieve of your spherical Ti for a slightly different effect. Even just tossing it in straight out of the bag would probably work. Sponge burns much faster than spherical so it could be very interesting. I may just make a batch using some of my 60 mesh spherical Ti. video: http://pyrobin.com/files/slow%20gold.avi Potassium Nitrate 36 Charcoal Airfloat 29 Charcoal, 80 mesh 14 Sulfur 9 Titanium, sponge, 40-80 mesh 7 Dextrin 5 On passfire I see a silver streamer formula using "40-200" spherical Ti. It's just Chrys6 +20 Ti. 150-350 is an unusual grading of atomized Ti to see. EDIT: I just noticed this was in Pyro Comps - don't be surprised if this gets moved, as the pyrotechnics compositions forum is for posting new and established compositions for review, sharing, analysis - not so much to find a composition for your chemical.

psyco_1322 Posted October 23, 2008 Share Posted October 23, 2008 Thats about the Ti that skylighter sells, I bought some of the coarser stuff to try in a slow gold formula but haven't got around to it yet. Link to comment Share on other sites More sharing options...
xxxjanusxxx Posted October 23, 2008 Share Posted October 23, 2008 Potassium Nitrate 36 Charcoal Airfloat 29 Charcoal, 80 mesh 14 Sulfur 9 Titanium, sponge, 40-80 mesh 7 Dextrin 5 I've made a batch of these, but they're not burning very well. Most of the batch is still drying, but I've forced some of them to dry by heating them up a bit. Results are a TT like star, but not as intense. The Ti doesn't result in any effect at all. I properly used Ti sponge 40-80#. Next time I will use TT as base for Ti streamers or the meal variety of 60-30-10. Add 10 to 20% Ti -80#. I think 40- 80# is to coarse.

FREAKYDUTCHMEN Posted October 23, 2008 Share Posted October 23, 2008 These type of stars burn only well hight in the sky. They take oxigen from the air to burn proper. Always test your stars in a stargun or in a shell or something. Link to comment Share on other sites More sharing options...
Mumbles Posted October 23, 2008 Share Posted October 23, 2008 When burnt on the ground, the slow gold formula gave me only a solid glowing glob of slag. In the air it is beautiful. I use a slightly modified form, and it hangs in the air for the better part of 30 seconds or a minute. I should have a video coming soon to show this. It also depends on what size of shell you're making. If you're making 3" shells, then perhaps this formula isn't suited to you. If you're making 8" shells, then it's just fine. Everything is relative. Hang time has little to do with the size of the star. Link to comment Share on other sites More sharing options...
tentacles Posted October 23, 2008 Share Posted October 23, 2008 Mumbles, what's your modified formula? I'm very interested in a long hang time version of these. I used alder charcoal for this batch, and the burn rate obviously reflects this, though the hang time kind of lacks. Next batch I may use a slow charcoal for the 80 mesh and alder for the AF, see how that does me. Granted, even with the original formula, if you use slow charcoal (commercial airfloat) the hang time is considerable and the burn rate makes 1/8-3/16" stars perfect for a 4" shell. The stars in that 3" shell in the video were 3/16-1/4". Link to comment Share on other sites More sharing options...
Ericz Posted October 24, 2008 Share Posted October 24, 2008 (edited) Hi folks , What you could try is this : Tiger tail :44 kno344 C6 S6 Dextrine ( or NC lak ) + 14 Ti The name of this composition is Willow Diadeem here a movie of it : http://www.youtube.com/watch?v=zi6EAC6GED0 I hope this will help you some with your Ti Ciao !

FREAKYDUTCHMEN Posted October 24, 2008 Share Posted October 24, 2008 That's no TT, that is a willow composition with Titanium added. Link to comment Share on other sites More sharing options...
Ericz Posted October 25, 2008 Share Posted October 25, 2008 Yea , thats just TT with Ti ? Whats the problem ? Its a very nice composition iam gonna make it lots ! The composition is for SURE TT . Grtz . Link to comment Share on other sites More sharing options...
ExplosiveCoek Posted October 25, 2008 Share Posted October 25, 2008 FreakyDutchmen IS the builder of this shell.. I guess he knows what he put in the shell better than you do, and that definitely wasn't TT with Ti. Link to comment Share on other sites More sharing options...

Mumbles Posted October 29, 2008 Share Posted October 29, 2008 Tentacles. Sorry I forgot to answer. I replaced half of the Titanium with -20 mesh Aluminum flitters. I don't know where I saw this trick, but the effect is amazing. They hang a LONG time. PM me for a video. I don't have it rendered yet, and it's on my school server, so it's not ready to share with the public yet. Link to comment Share on other sites More sharing options...
Brakkie Posted October 29, 2008 Share Posted October 29, 2008 Maybe this is the effect you're looking for? I used coarser Ti but the effect should still be similar. TT +15% Ti Link to comment Share on other sites More sharing options...
Mumbles Posted October 29, 2008 Share Posted October 29, 2008 Are you looking for something along the lines of this? http://www.apcforum.net/files/mumbly5.wmv It's a brocade formula that I made burn too fast obviously. I didn't even mill it! Nice effect, but useless as a brocade. Looks real nice as a spider shell though. Needs more 80 mesh charcoal in either case. However, the mesh size of Ti you have will be far too fine to get an effect like this. Best case scenario, you can get a tad of shimmering in the tail of a silver streamer. That being said, something as simple as a green meal with 10% Ti will probably make a mighty fine star or comet for you. Link to comment Share on other sites More sharing options...
TheSidewinder Posted October 29, 2008 Share Posted October 29, 2008 That was a gorgeous mine, actually. Very nice, and long-duration, sparkle. Who provided the commentary? Link to comment Share on other sites More sharing options...
Brakkie Posted October 29, 2008 Share Posted October 29, 2008 It was supposed to be a 2" shell but turned into a flowerpot. I don't know! That guy has been posting on some of my video's WELL before I post them on any forums! I guess I got a stalker or some sort lol. I was just referring to this because although my Ti was coarser, this might be the effect he was looking for! Just make sure to mill the TT as long as you can and make SMALL stars! These stars weren't bigger than 4mm! Link to comment Share on other sites More sharing options...

Mumbles that was a different looking star kind of cool what was the formula if you dont mind sharing. I guess im not up on brocade formulas.

xxxjanusxxx Posted November 3, 2008 Share Posted November 3, 2008 Potassium Nitrate 36 Charcoal Airfloat 29 Charcoal, 80 mesh 14 Sulfur 9 Titanium, sponge, 40-80 mesh 7 Dextrin 5 To give you an update about these stars I've made recently. They ought to be dry by now, they even layed on the radiator the last week. I've tested several in a stargun, but the results are bad. The star burns a bit like TT, but not as intense, sometimes a bit of Ti begins to burn, but not as the effect showed in the video. The hangtime of te parts of Ti that actually burn are beautiful, but there isn't much of an effect in the whole star. I don't know what may be wrong, but I've really used the same composition and the same meshvalue of Ti. I've made the desired effect though, but with -80# Ti sponge in just a simple 60-30-10 (KNO3-C-S) rocketfuel composition. It can be added up to 50% by weight of the used rocketfuel. These stars burn faster than the stars seen in the video though. Perhaps I will post some starmines of these stars, to show the difference.

oskarchem Posted November 3, 2008 Share Posted November 3, 2008 Maybe the fact that you dried them on the radiator caused this. It happened to my TT stars which I dried in a very warm room, a sort of crust forms on the outside, and the humidity inside can't get out. This is common in compositions containing a high % of charcoal. Link to comment Share on other sites More sharing options...

It happened to my TT stars which I dried in a very warm room, a sort of crust forms on the outside, and the humidity inside can't get out. This is common in compositions containing a high % of charcoal. The last week on the radiator was just extra. The stars dried naturally first, but still burnt poor, but were dry. So I've put them on the radiator to see if it might help, but the effects are the same. I'm busy finding the right software for editing, so please wait a bit and I'll post some video's. EDIT: Here it is starmines_edited.wmv The first mine represents the composition mentioned earlier and the second the rocketfuel with 50% Ti -80#.
