In fact, fireworks and firecracker structure similar to its structure contains black powder and medicine cited. In order to achieve good performances, fireworks and shells are filled with a large amount of gunpowder for launching and exploding. For example, a 20-centimeter diameter shell fired up to an altitude of about 200 meters will explode, These stars cover the radius of about 80 meters.

The process of making fireworks also add some luminescent agents and hair color agent can make fireworks emit colorful colors. The luminescent agent is a powder of metallic magnesium or metallic aluminum. When these metals burn, they emit incandescent light. Hair color reagent is actually just some of the metal compounds.

In order to protect the environment, many fireworks and firecrackers formulations do not use heavy metals and sulfur-containing substances, thus reducing the generation of sulfur dioxide and other sulfides. The second is to reduce the amount of metal powder, the basic use of organic matter as a combustible material, thereby reducing the metal powder generated after inhalation of particulate matter. Third, by changing the amount of oxidants and combustibles to change the system oxygen balance and combustion temperature, control the combustion reaction.
