inside of fireworks

Fireworks that emit color-colored lights at night shows and festivals consist of a long tube-shaped hill that is usually made of cardboard and filled with a trace explosive mixture, as you know closely. Try a "pyrotechnic mixture" These flares are a special blend of air that can burn without oxygen. The candle burning through a closed cabinet goes out when the oxygen of the inside air is exhausted; However, if there is no air in the cartridge shell, this mixture continues to burn until it is exhausted. Because one of the substances in the mixture is continuously released into oxygen, it ensures that the burning phenomenon in the enclosed space is realized.

For centuries, potassium chloride (potassium nitrate) was used as an oxygen donor in the cartridge mix. As this salt is found in all eastern countries, the first fireworks made in the east were prepared especially in China and prepared from a mixture of saltpeter sulfur and charcoal. It is only in the 14th century that the gunpowder, the mixture of the same materials, is known in Europe as the black gunpowder and used as an explosive device in firearm bullets. However, for the very first time in history, powdered fireworks were used in China for war and demonstration purposes.

The Europeans were learned from the Chinese to make fireworks, and during the 13th century the flaschil was developed rapidly in Italy, then in France, and in all other European countries. Initially, only fireworks displayed at religious festivals have become very popular in large European cities in the 18th century. These displays, which are an integral part of national celebrations in almost every country, are usually led by experts.bold
