Notes In the late 1880s it was discovered that magnesium powder, if mixed with an oxidizing agent such as potassium chlorate, would ignite with very little persuasion. This led to the introduction of flash powder. It would be spread on a metal dish the flash powder would be set off by percussion - sparks from a flint wheel, electrical fuse or just by applying a taper. However the explosive flash powder could be quite dangerous if misused. This was not really superseded until the invention of the flashbulb in the late 1920s.
