History…:
History… It was invented in China in ancient times in 11 th century. They named it “Huo Yao” means fire chemical. Basically it is gun powder combination of Salt peter 75% Charkol 15% Sulpher 10%

Composition… Fuel: Charcoal, commonly known in the pyrotechnic industry as black powder is the most common fuel used in fireworks. Normally, all fuels will contain an organic element such as charcoal or thermite. Oxidizing Agents: The function of the oxidizing agent is to produce the oxygen needed in order for the mixture inside the firework to burn. These oxidizers can be nitrates, chlorates or per chlorates. Reducing Agents: The second part to a firework is the reducing agent. These burn the oxygen provided by the oxidizing agents to produce hot gasses. Common reducing agents are Sulpher and Charcoal. These react with the oxygen to form Sulpher dioxide and Carbon dioxide respectively as illustrated below. By mixing both the reducing agents, the speed of the reaction can be controlled. Regulators: Metals can be added to regulate the speed at which the reaction. The larger the surface area of the metal, the faster the reaction will proceed (collision theory).

Composition… Colouring Agents: Different chemicals are used to produce different coloured fireworks. Therefore, in order to produce a firework of a certain colour, the correct corresponding chemical or as the case may be, mixture of chemicals can be used: Metal Colour Strontium Red Copper Blue Barium Green Sodium Yellow / Orange Calcium Orange Gold Iron Strontium / Copper Purple
Composition…:
Composition… Binders: Binders are used to hold what is essentially the mixture of the firework together in a paste like mixture. The most commonly used binder is known as dextrin, a type of starch which holds the composition together. Paron can also be used in binding, however it is less common and only used in conjunction with red and green fireworks as it helps to enhance their colour. The binders do not actually begin to work until the firework has been lit as they are too unstable for storage within the firework and are hence potentially dangerous.
