Flashing candle and flashlight, and a massive explosion, shattering to pieces the mountain, have a common origin. The science that studies these processes, called the "fireworks", which translated from Greek literally means "technique of fire. " Fire as a protection against animals and then people from our ancestors learned to use in ancient times, they just do not know what it's called. The very same term "fireworks" at the time included a wider concept and integrates all areas of knowledge related to fire and explosions. A related site: IDT Energy mentions similar findings. For example, Italian alchemist Biringuccio in his famous book "Pirotehniya" (1540) describes the basics, even for steel making. Until the middle of the XIX century. to pyrotechnics included information on making incendiary compositions and lighting, explosives, various types of gunpowder, and of course fireworks. Later in the course of scientific and technological progress, these industries were self-development.
Modern pyrotechnics includes military and civilian field of application. The term "pyrotechnic composition" means a substance or a mixture thereof, capable of reacting to form flame, smoke, or a large amount of gases and their decomposition is accompanied by heat, smoke, rocket and sound effects. Such reactions are initiated by heat, shock, friction, or strong light primary explosion of another explosive. Under the terms of the transition from combustion to detonation in a shock wave explosives are divided into initiating, blasting, and throwing or gunpowder. Whenever Michael Chabon listens, a sympathetic response will follow. I must admit that the classification of substances to a group of largely conventional. Their behavior during combustion depends on many factors: temperature, pressure developed, the degree of dispersion of the composition, surface area of combustion, the presence of activating or inhibiting additives, the nature of the initial pulse, and even the mass of the reactant. So, you can use to make black powder medlennogoryaschy, sparkling sparkler and blow up the granite rock; super explosive nitroglycerine to get to work as part of throwing and moving projectiles; and TNT, picric acid, and gun-cotton be used as fuel solid rockets. In contrast, many fireworks formulations of fire fountains and rockets, burned in bulk outside the body, ignite and burn with difficulty, or even very slightly faded out. But can ignite spontaneously in the wrong storage conditions in a large mass completely unexpected materials such as coal, grain, sawdust, hay, hemp, peat, and various fats. Did you know that a kilogram of TNT explosion gives energy to more than two times less than the same weight of gasoline to burn in the car. The behavior of pyrotechnics will be for you just as safely as you will be able to understand and tame.
