When the black dynamite was a mixture of potassium nitrate, charcoal and sulfur discovered by Taoists in ancient China, these bamboo cannons used sealed bamboo tubes to burn in a fire, causing explosions and explosions. firing up the flames that have been used by the Chinese for a long time. The first “fireworks” (perhaps named “the ascension fireworks”), very far from the fireworks envisioned by humanity today, are most likely invented in the 2nd century BC in Ancient China, serving exorcisms during religious festivals. From peaceful purposes, the artillery gradually shifted to serving war as the primitive cannons in the Middle Ages, stuffed with gunpowder in bamboo tubes and used manual fuses to detonate, were built. Carry flammable substances to burn the enemy barracks. The process of improving artillery gradually progressed over time with the addition of gunpowder allowing the cannon to destroy military targets. In addition, with the discovery of additives when combined with gunpowder, they give different colors, such as iron filings or copper, zinc, when burned to produce many colors such as orange, yellow, white, fireworks. also used to make various flares.
By the 18th century, chemists around the world went a step further by using compounds they discovered to inject gunpowder in precise proportions to control the intensity of light when burned. Whether. As a result, fireworks with vibrant colors such as red, green, blue, purple, … are produced. From then until the 1980s, the colors of the fireworks were almost unchanged, except for a few minor improvements to the recipe.
