Zumber Posted March 22, 2012 Posted March 22, 2012 It would be appreciated if anyone could suggest me a good white star using following compoundsBaNO3,Aluminium (any type,fine),red iron oxide,and sulferI dont want shimizu's whitecore star composition and other kno3 based star.
Peret Posted March 22, 2012 Posted March 22, 2012 I have never heard of a white star comp that uses iron oxide. I can recommend this one, though - "luce forte" - Barium nitrate 64Potassium nitrate 8Sulfur 5Dark aluminum 19Dextrin 4 These are extremely bright, but difficult to light. I had a lot blow blind in shells and gave up on them, until recently I was using up old stars and put them in a mine. They all lit and we nearly suffered retinal damage from the brightness.

Mumbles Posted March 22, 2012 Posted March 22, 2012 Replacing some of the barium nitrate with potassium nitrate will reduce the brightness.
Peret Posted March 23, 2012 Posted March 23, 2012 Replacing some of the barium nitrate with potassium nitrate will reduce the brightness.Right, it's the incandescent barium oxide that mainly contributes the light. Just prime them well with silicon in the prime. White stars are interesting from a technical point of view, because it's so hard to make them pure white, but from a display point of view they're a bit disappointing in my opinion. I haven't made any for a while and have no plan to.

mabuse00 Posted March 24, 2012 Posted March 24, 2012 Barium oxide is a decomposition product of Barium nitrate.Barium oxide itself is useless unless you heat it. It would be just some dead mass in your mixture and won't contribute anything to the reaction.
Peret Posted March 24, 2012 Posted March 24, 2012 Swap, the barium oxide I referred to is produced in the flame from the decomposition of the barium nitrate. You would never add it to a composition. In the same way, if there's a chemical present that releases chlorine, then barium chloride is produced instead of oxide and the flame is green. Again, you never put barium chloride in the mixture.
Zumber Posted March 25, 2012 Author Posted March 25, 2012 why not to use barium chloride in composition i mean insted of using pvc what if bacl2 is used alongwith ba(no3)2,sulfer and aluminium.

Because Barium Chloride WILL NOT BURN, neither will it produce oxygen to help anything else burn. It's dead weight. The one useful barium compound that carries enough chlorine to burn green is barium chlorate. You don't seem to understand the most basic chemistry, swap. You will never succeed in making good stars by trial and error alone without understanding the processes. I strongly recommend you get a decent pyro book and spend some time in the materials and chemistry sections.
