firetech Posted March 31, 2009 Posted March 31, 2009 Does anyone have some relatively simple Ti compositions? For fountains, streamers, rockets etc. Bp/Ti ratios?
a_bab Posted March 31, 2009 Posted March 31, 2009 Generally speaking, for rockets you can add around +5% Ti or Fe or MgAl etc. For the rest it's pretty much like "take your favorite formula and add +5-10% Ti". The use of sferical instead of granular Ti would greatly improve the safety.

Miech Posted March 31, 2009 Posted March 31, 2009 For streamers and fountains you can use tiger tail composition with 10% titanium added to it. It is not recommended to ram things with titanium, but I don't know if there have actually been accidents with it. For rockets just add 2-5% titanium to your fuel before ricing it (wet, granulate, dry). Ricing prevents the titanium from settling at the bottom of the jar, it's quite good in doing that. Rockets with titanium should be pressed as well.
firetech Posted March 31, 2009 Author Posted March 31, 2009 Ned Gorski claims that it can be hammered...I have spherical Ti which is much safer than flake, granular or sponge type titanium.
psyco_1322 Posted April 1, 2009 Posted April 1, 2009 You can hand ram rockets with Ti in them, as long as the fuel is rammable, ie its bp based. Ti will spark against itself and that why its advised to be cautious when ramming with it.
FrKoNaLeaSh1010 Posted April 4, 2009 Posted April 4, 2009 For my fountains I always used a BP/metal fuel combo using either 75/25 or 80/20 ratio. The larger the mesh of the metal the larger the sparks wil be. For fountains I like a higher mesh something like -80 and for rocket tails you only need to add like 5-8%. Something like a tiger tail or chrysanthemum star formula would be a good base but it would also produce a lot of charcoal sparks on top of the titanium. I believe this mix is known as a firefly comp. If you just want the titanium effect meal powder with added titanium would suffice but if you use tigertail or similar charcoal star it will be a mix of orange and whitish silver which still looks cool. The meal powder by itself doesnt make too much charcoal sparks and shows off the titanium a little better
baran420 Posted February 6, 2010 Posted February 6, 2010 Hello, Despite the great wealth of pyrotechnic material on the net I am surprised to see such little discussion on titanium effects (I do however have dial-up internet and negligible patience). Can any one direct me to a detailed discussion on the subject? My aim is to pretty up ordinary BP mixtures in gerbs, rockets and crackers with white sparks/trails etc. I am unsure wether to buy flake, sponge and in what mesh size. Any help would be appreciated p.s. Bonny the link you gave seems to be a dead end??
psyco_1322 Posted February 6, 2010 Posted February 6, 2010 Well, there really isnt anything that discusses on that wide of a range of uses. The same thing kind of goes for aluminum's, there are so many uses and types that general rules are hard to make. Most formulas, using Ti, will tell you what type to use. Different effects use different types of Ti, and different sizes. Atomized Ti isn't used for many bright spark applications. Flake is going to be good for sparks and tails on comets and things that are large. Sponge is a little more reactive and is usually used in smaller meshes for stars that are rolled and for sparks in things with nozzles. Mesh sizes vary for application, salute sparks usually use large mesh Ti so the sparks hang for a while. Stars use smaller mesh for ease of making and to not drown the effect too much with excessive long tails and durations of hang time. You will end up with several different meshes for several different applications. The more sizes you have, the more you can control the effect you're looking for. I personally have about 6 different types of Ti that get used for verious things, and will likely collect more as time goes by. You can't have too many. For you're uses, I would look for a sponge or flake Ti. If you are hand ramming the rockets and gerbs and not pressing them, lean more towards flake, its less reactive and will be safer. If you are pressing them, which is what I suggest you do, you could use a sponge Ti. Shoot for something in the range of 30 mesh, that will give you something that will work from one device to another while producing a nice effect.
derekroolz Posted February 7, 2010 Posted February 7, 2010 If you want a formula with just mainly the titanium effect I recomend using the 5cent pyro fuel of 65:35 KNO3/sugar. Like said before it is best to use spherical rather than flake, becasue of saftey, always press not ram when ever possible. Pressing also produces the most consistent results. But the 5cent formula can sometimes not be as strong, but it will work for just basic rocket. The reason I use the 5cent fuel is because when it burns it usually burns with minimum to no spark. However, I did have one that was almost like a BP rocket, I think it was just the wood of rocket that did this.
