The Chemistry of Pyrotechnics: Stars, Flares, and Color Mixtures
Most pyrotechnic mixtures follow a very simple set of chemical rules. Most mixtures contain an oxidizing agent, which usually produces oxygen used to burn the mixture, and a reducing agent, which burns to produce hot gasses. In addition, there can be coloring agents to impart a color to the fire, binders, which hold the mixture in a solid lump, and regulators that speed up or slow down the speed at which the mixture burns. These are not all the possibilities, but they cover most all cases.
Coloring agents are very interesting. It’s long been known that various metals produce different colored flames when burned in a fire. The reasons are buried in the realm of quantum physics, but the results are what matters, and we can present them here.
Formulas, explanation and preparation for Stars, Flares, and Color Mixtures have been explained well in this report.
