$13.00 PER POUND
Antimony trisulfide is a black powder. It is a fuel used in various white star compositions of the potassium perchlorate-base. It is sometimes used in glitter compositions, fountain compositions and flash powder, however, it is used less and less for flash powder as it is very poisonous and can usually be replaced by sulfur or completely omitted. Flash compositions containing antimony trisulfide are very sensitive to friction, shock, and static electricity.
