Flash powders are classified as detonating pyrotechnic mixtures that deflagrate when unconfined and detonate when confined, emitting an intense light under both conditions. Their legitimate uses include commercial fireworks and military ordnance and simulators. The relative ease of acquiring the chemicals needed to manufacture flash powder has made these mixtures attractive to the amateur bomber. Approximately 15% of the several hundred bomb cases processed annually by this laboratory involve the use of flash powder mixtures.
