Zumber Posted April 14 Posted April 14 If you click search option you will get lots of white stars formulations. If you are desire particular effect then post more information on what exactly you wants to do.
Crazy Swede Posted April 14 Posted April 14 My favourite white star formula in the non-metal fuelled category is: 62 % potassium nitrate 18 % antimony trisulfide 18 % sulfur 3 % dextrin It might be too quick burning for some applications but I guess increasing the amount of fuels should reduce the burn rate without making it less white. 1
Zumber Posted April 15 Posted April 15 Just simple white peony star effect is acieved using Barium nitrate potassium nitrate sulphur magnelium dextrin. Or by using fine flake aluminium and magnelium together. Antimony trisulphide is toxic.
Crazy Swede Posted April 15 Posted April 15 Antimony trisulfide is no big deal in fireworking when it comes to toxicity because of its insolubility. Just wear a simple dust mask and you will be ok. Its combustion products may be another thing but it has been used for over 200 years in pyrotechnics without causing much trouble to the workers and spectators.
kingkama Posted April 16 Posted April 16 A simple perchlorate magnalium star without PVC or chlorine donor would burn in a White flame Better with Copper and barium compound inside,

Potassium perchlorate produces excellent white star effects but we are limited to nitrates only.
