In 1865 Traill Taylor first used magnesium flash powder to obtain instantaneous exposures without any other light source.

The original Agfa Flash Lamp used matches to ignite the powder, that method was replaced by a wheel turned by a spring moving against a flint. As well as being used in the hand a small stand could be attached in place of the handle and fired by a bulb or wire release.

These flash guns were little more than a stick with a platform that you could use to hold the potassium chlorate and magnesium. They were connected directly to the camera, usually with the photographer holding the flash aloft, so that when the camera’s shutter actuated, it triggered the …

It is widely used in theatrical pyrotechnics and fireworks (namely salutes, e.g., cherry bombs, M-80s, firecrackers, and cap gun shots) and was once used for flashes in photography. Different varieties of flash powder are made from different compositions; most common are potassium perchlorate and aluminium powder.
