eb11 Posted April 22, 2014 Posted April 22, 2014 I am wondering if anyone would know if titanium would make a star burn faster. I am making parlon stars and they are burning faster than last year the only thing I am doing differently is the prime I am doing fence post instaed of meal. I don't think this would make a difference but who knows
FlaMtnBkr Posted April 22, 2014 Posted April 22, 2014 Ti can increase the temp and burn speed. How are you determining burn speed compared to last year?
eb11 Posted April 22, 2014 Author Posted April 22, 2014 from videos that I have of last years shells. the ones I am making now are burning fast I used ti in them last year an they didn't burn this fast
Bobosan Posted April 22, 2014 Posted April 22, 2014 Fencepost has silicon and D.E. which is supposed to cause an extremely fast and hot flame that engulfs the star quickly.
FlaMtnBkr Posted April 22, 2014 Posted April 22, 2014 (edited) I guess if you added a lot it could possibly act as a heat sink and burn in the atmosphere. What formula are you using? The parlon brilliant stars? I wonder if you could add the appropriate carbonate to slow it down. Bob, I though the silicon and DE was supposed to form a hot molten slag that holds heat for a long time and not burn extremely fast? Edit: If they are the brilliant parlon stars, they call for a hot prime. Maybe if you just used BP it only lit the surface in a couple places and the fencepost is lighting the whole surface so burning faster? I guess that is what you meant Bob? I assume they are cut or screen sliced? It might just take some experimentation but the ones I have made do burn fast for their size. Edited April 22, 2014 by FlaMtnBkr

Yeah, that's what I understand, FMB. Not only does the silicon create the hot slag but the DE creates a very porous surface allowing the flame to propagate faster over the entire star. As you mention, the BP prime may not quickly ignite the star over the entire surface.
eb11 Posted April 22, 2014 Author Posted April 22, 2014 I will use the prime I used last year and see if it changes the burn rate
eb11 Posted May 5, 2014 Author Posted May 5, 2014 (edited) I took out the ti and the stars burned fine I put it back in on the next small Bach to try it and they burned fast again so I would have to say its the to Edited May 5, 2014 by eb11 1
jessoman Posted May 9, 2014 Posted May 9, 2014 I agree with Bobosan about the stars being evenly lit with a nice hot prime. Are you just putting a small amount of prime on, 1mm? I find it works best like that.Was Ti in your fence post? Make the stars bigger ?
eb11 Posted May 10, 2014 Author Posted May 10, 2014 I was actually using my wrong size dowels for the star size. I moved this winter and found my dowels that I used last year they are 7/16 and I use a hacksaw blade to cut them at 3/8 perfect size so sorry for the confuson
jessoman Posted May 10, 2014 Posted May 10, 2014 Hehe, that's funny, size was the first thing I thought of but I thought it would be a bit weird to say it- so I jokingly mentioned it at the end.Your little pyro book must have all the details of your methods of comps you have done over time As for Ti, in rockets I have found it slows the delay down. In my opinion (contrary to what had been said) :?
