ThunderEx Posted May 1 Posted May 1 Never seen a white comp with barium carbonate!? It's used as a green colorant with a chlorine donor at high temp, to my knowledge.
Sulphurstan Posted May 1 Posted May 1 Are you sure you don't confuse with Ba Nitrate? Which can be used in some white star compositions? 1
Zumber Posted May 2 Posted May 2 He might not be having barium nitrate in hand and only posses barium carbonate.

Zumber Posted May 6 Posted May 6 Dont use Chlorate you seem you are new to this hobby. Just learn simple formulations first like BP charcoal stars first. Never use chlorate stay away from it. I also recommend to postpond white stars. 1

Chlorate Is not more reactive than other oxidizer if you don't use sulfur, im in professional fireworks from many years, and chlorate Is Irreplaceable for some applications. So if you have chlorate, some shellac and some MgAl you have all you Need for a White star mix

In history only chlorate is responsible for many death and accidents and still today. 1

In history only chlorate is responsible for many death and accidents and still today. Telling people not to use chlorate because it is dangerous is equivalent to a lack of information, no one explains how and why but everyone says no.This is a dangerous hobby, 100 grams of gunpowder is enough to have an irreversible burn to the lungs and die in a few days or have third degree burns. There is no time to run away like in the movies so since you always have to be careful, in a humid environment and with acidic sulfur it is better to avoid chlorate which produces chloric acid which could cause Unwanted ignitions, no one suggests having short nails to avoid scratching the fabric of the sieves, no one says to use a sieve for each family of mixtures and so on.... 2
Dragon99 Posted May 8 Author Posted May 8 It would be great if someone told me easy white star composition.(any)
Zumber Posted May 8 Posted May 8 White star Potassium Nitrate- 6000 Sulphur -1500 Magnelium( 200 mesh coated)-2000 Aluminium powder flake bright (-400 mesh)-1000 Charcoal (-200mesh)-500 Dextrin -600 Boric acid-50 If you could have barium nitrate it would be great Sieve potassium nitrate Sulphur magnelium charcoal boric acid together 3 times using 40 mesh screen then mix aluminium powder. Wear proper safety gears. Try out 100 gram batch careful of nitrate aluminium reaction (boric acid is added but still watch out).

Zumber Posted May 15 Posted May 15 Preparing aluminium powder on your own is dangerous job. Aluminium is highly reactive and you cant make it into very fine powder. Its worth and wise to purchase it commercially than preparing on your own. You might replace it with magnelium for white but it will alter its effect.

I make a formulation based on chlorate and don't use sulfur About 2015 Barium nitrate/potassium chlorate and shellac They're ignite so hard and I decided to remove primer whit my hand and a piece of wood They are ignite by friction and happen what happen After that I never use chlorate.

In this opinion chlorate/sulfur is not dangerous too Of course I was amateur in 2015 but danger is not 0-1 It's 0-100 Somone can accept risk of 90 an do something But I decided to be cautious,even I lost some effect or pay more for perchlorate My friend die in jun 2022 during make of Dragoneggs.he works at least 20 years in pyrotechnics and he probably makes tons of that before,but everyone can makes mistake! I'm just trying to say be carful as much as you can 1
