Pyrotechnic composition
From Wikipedia, the free encyclopedia
A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas or smoke or a combination of these, as a result of non detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction and include flash powder, gunpowder and coloured fire compositions.
