Fireworks and firecrackers are similar in structure and all contain black powder and drugs. In order to achieve good performance, fireworks and fireworks bombs are filled with a lot of gunpowder for launching and explosion.
In the process of making fireworks, some luminescent agents and chromophores are added to make the fireworks emit colorful colors. The luminescent agent is powder of metallic magnesium or metallic aluminum. These metals give off incandescent light when they burn. Chromophores are actually just some metal compounds.
Metal compounds contain metal ions. When these metal ions react violently with oxygen molecules, you will see the compound burn and emit a unique flame color.
