Pyrotechnics, the art of fire
Pyrotechnics, the art of firePyrotechnics is defined as the art of manufacturing or setting of fireworks. There are many different forms of pyrotechnics. Some consider fireworks dangerous, obnoxious bursts of noise; others consider them beautiful, artful displays of light. Either way you look at it, pyrotechnics is an interesting and dangerous hobby. Many colors and designs may be created by the placement of different compounds in distinct areas of the fireworks, either projectile or stationary ones.
Some of the many different colors of the visible spectrum that can be easily recreated are; yellow, orange, red, green, and blue. The shades of yellow and orange can be easily recreated by the use of sodium or calcium chlorate. Red is easily attainable by the burning of SrCl. The burning of BaCl creates a very bright green. The burning of copper chlorate creates the blues. It would be extremely easy if we could just place these in the fireworks and have them work, however, the emitting molecules, especially SrCl and BaCl, are so reactive that they cannot be packed directly into a firework. To generate them, we need pyrotechnic compositions designed to generate the above molecules, to evaporate them into the flame and to keep them at as high temperature as possible to achieve maximum light output. To get good colors, there must be substantial amounts of emitters present in the flame. The emitters are not alone: in order to achieve the high temperature, a fuel - oxidizer system is also needed, as well as some additional ingredients.
