PHOTOFLASH POWDER COMPOSITION #12
SOURCE: PSM
COMMENTS:
DANGER/CAUTION
Magnesium-based flash powders are more sensitive and violent than those made with aluminum. Individuals inexperienced with flash are encouraged to avoid such compositions.
Chlorate and sulfur/sulfide mixes are known to be very sensitive to shock, flame, spark, and friction. They decompose faster than perchlorate mixtures.
