Chemical powder consisting of a mixture of metallic magnesium and an oxidizing agent. Ignited by heat to produce a brilliant flash of light.
A more potent form of gunpowder created by adding a metal powder to black powder. Widely used in fireworks especially noise and maroon effects, as it also creates a bright flash. Fireworks containing flash powder can be subject to greater restriction on storage and transportation.
An explosive composition typically containing potassium perchlorate and powdered aluminum that when ignited produces a bright flash of light, usually with a loud audible report.
Mixtures that contain powdered aluminum or a magnesium/aluminum alloy which, when ignited, can result in a powerful explosion and flash.
Used in the early days of photography, a mixture of metallic magnesium with an oxidizing agent that, when ignited, produces a bright flash of light.
A silvery chemical mixture usually consisting of potassium perchlorate and finely powdered aluminum. It is used as the explosive component of firecrackers, aerial salutes, and the reports in rockets and roman candles. Flash powder is very dangerous to manufacture.
Flash powder is a mixture of oxidizer and metallic fuel which burns quickly and if confined will produce a loud report. It is widely used in theatrical pyrotechnics and fireworks (namely salutes, eg. cherry bombs, M-80s, and firecrackers), and was once used for flashes in photography.
