History of Fireworks

Around the 9th century, a cook by accident mencampurtiga ingredient of black powder (black powder) or the salt peter potassium nitrate, sulfur (sulfur), and charcoal from wood (charcoal), which comes from his kitchen.

New at the time of the Song dynasty (960-1279 AD) was established fireworks factory that later became the basis of the manufacture of fireworks as more emphasis on colors and shapes borax fire in the sky until finally indistinguishable. The tradition of fireworks and then spread to all corners of the world.

The raw material tube is replaced with a roll of paper which is then wrapped in red paper the outside. Then the fireworks is the basis of making fireworks, which is focused on the colors and shapes borax fire in the air.
during the Renaissance, in Italy and Germany there are special schools that teach the problem of making fireworks. In Italian school emphasizes the complexity of fireworks, while in Germany the school emphasizes the advancement of science. And finally the term that describes the art of pyrotechnics fireworks. To make fireworks needed an expert who understands the physics and chemical reactions. After many years, experts fireworks could eventually make colorful fireworks, like the red that comes from strontium and lithium, the yellow color derived from sodium, the green color comes from the blue color of the barium and copper. The chemical mixture was formed into small cubes called a star. Star this is what determines the color and shape when the fireworks went off later.

Chemical explosives are divided into two kinds, namely low explosives (explosive power is low) and high explosive (high explosive power).
Explosives low explosives are explosives that have a low explosive detonation velocity (velocity of detonation) between 400 and 800 yards per sekond While explosives have a high explosive detonation velocity between 1000 and 8500 meters per sekond low explosives Explosives are often called propellant ( booster) that is widely used as the bullets and rockets.
Among the explosives are low explosives known gunpowder (black powder or gun powder) and smokeless powder. For some communities in Indonesia, gunpowder is widely used as a maker of fireworks, including firecrackers and bombs rock fish. Gunpowder is the oldest type of explosives discovered by the Chinese in the 9th century. Aside from being a material for firecrackers and fireworks, gunpowder is widely used as bullets and rocket propellant, rocket-signals, fireworks, explosive fuse, and fuse explosive wait.

Perhaps because the regulation is outdated and too "antique", the government has issued various regulations, including the 1951 Emergency Law yanag threats can reach 18 years in prison.
