Fireworks
Fireworks are a type of low-explosive projectile used because of their beauty for entertainment, often to celebrate various holidays and events as part of a fireworks display, especially at New Year's Eve celebrations. There are several forms and combinations of fireworks that ensure access to the basic elements of the display,The most important ones are lighting, color, shape, smoke, noise, as well as revolutions. Fireworks are made from a combination of chemicals that, when ignited, give many colors, and the degree and variety of these colors are controlled according to the type of chemicals used, designed to give flames and sparks in specific colors including red, orange, yellow, green, blue, purple and silver. Fireworks are different from firecrackers at their destination, as explosives create colored lights, while firecrackers make noises and no noticeable lights.
The first to invent fireworks were the ancient Chinese in the 7th century, and their use spread because they believed they were useful in scaring and exorcism, and fireworks remain edifying one of the pillars of chinese New Year's celebration or the Moon Festival. The invention of fireworks was a natural result of the invention of gunpowder, one of the four great inventions of ancient China. China is currently the world's largest manufacturer and exporter of fireworks.
Fireworks generally consist of a cylinder or tube made of plain or reinforced paper that encapsulates the flammable material inside. Several cylinders or anabs with different varieties are usually combined with each other, which, when ignited, gives a variety of shapes and colors. Fireworks are either fired in the form of a mortar-like shell or have self-propelled power like a rocket.
The fireworks were originally inspired by the use of Greek fire from 670 AD, which was sent to enemies in primitive ways in the form of liquids or flaming shells. It was enough to ignite a mixture of resin, sulphur, bitumen oil and powdered salt (sodium nitrate) to obtain a flammable flame away from the launch site. Since the beginning of the ninth century, the Chinese have been able to make black powder (gunpowder), which, when ignited, emits huge amounts of gas that push the shell away. The gunpowder industry was moved to Europe by the Arabs in the 13th century and was used in wars and on the holidays thereafter. Until the 19th century, fireworks remained primitive and simple to install in terms of lack of colour, diversity of shapes, etc. With the advancement of chemistry and physics and pyrotechniques, new products of fireworks components have been developed.
The first documentation of fireworks dates back to the Tang dynasty when the Chinese invented them for their celebrations, later becoming part of Chinese culture and traditions, and from China spread to other cultures and societies. [1] The Chinese believed that fireworks could exorcise evil spirits and bring them luck and happiness.
The art and workmanship of fireworks preparation in China evolved into an independent craft, and its makers were respected for their knowledge of complex mixing, installation and launch techniques during performances. [3] During the Song dynasty (960–1279), the general public in China could buy different types of fireworks from market vendors; Huge fireworks displays have also become familiar. In 1110, a huge fireworks display was held during a military parade to entertain Emperor Song Huisong and his court. [5] In a record dating back to 1264, the incident of the launch of a rocket from fireworks was recorded near empress Gong Xing, which terrified her during a ceremony in her honor from her son Emperor Song Letsong. [6] Rocket-propelled grenades were common at the time in war, as evidenced by the Huolongjing Tinting Booklet, compiled by Liu Bowen and Jiao Yu
of gunpowder and fireworks moved to the Arab world in the mid-13th century, where Hassan al-Rameh wrote war-related manuscripts on rockets, fireworks and firebombs using terms indicating knowledge from Chinese sources, such as his reference to fireworks in the name of Chinese flowers
In conjunction with the spread of Chinese decoration in Europe in the mid-17th century, the presence of fireworks began to become familiar,[9] as his first appearance was admired by the public, according to Lev Izmaylov, Peter the Great's ambassador to China: "They make fireworks like no one in Europe has ever seen." [9] Amedy-François Frédévré published his review edited thesis on fireworks Traité des feux d'artice pour le spectacle in 1747,[10] describing the use of fireworks for entertainment and ceremonial ceremonies. In 1749, the musician George Frederick Handel composed the royal fireworks band to celebrate the Treaty of A chabelle (Treaty of Aachen)
In 1758, during his stay in Beijing, the Jesuit Pierre Nicolas Dancarville codified the chinese fireworks industry and installations and sent them to the French Academy of Sciences, which revealed the correspondence and published it five years later. [11] In 1765, these blogs were translated into several languages, resulting in the revelation of the secret of this workand the spread of fireworks among the people.
Fireworks use
The fireworks parade, which penetrates the night sky, accompanied by loud explosions and bright colors, has become one of the traditional symbols of the national and national holidays of some countries of the world. Its principle is based on the work of matches, consisting of a combination of chemicals such as potassium chlorate and sulfur with a flammable substance, as well as used in the manufacture of smoked grenades, signal and lighting meteors, They are also placed on the edge of private equity and illuminated shares used in guidance or alert to imminent hazards such as warning lights on highways, railways and at sea
