Can anyone give me white star formula using barium carbonate?

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.

Are you sure you don't confuse with Ba Nitrate?  Which can be used in some white star compositions?

He might not be having barium nitrate in hand and only posses barium carbonate.

What oxidizer did you have? Carbonate works well with per/chlorate yeald white without PVC using a metal fuel.

All my oxidizer? KNO3 KClO3 NaNO3

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.

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

You are experienced but it is not recommendable for very new person to deal with chlorate.

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....

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).

Is there any way to make aluminum powder without ball mill?😅

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.
