Abstract
Fuel-oxidizer mixtures based on potassium chlorate or sodium chlorate are well known. These mixtures have interesting properties of deflagration and are often used in propellants. Drastic reactivity of alkaline chlorates with ammonium salts due to the formation of ammonium chlorate NH4ClO3, a very unstable salt, is famous. By analogy, we tested the reactivity of different molecules containing nitrogen atoms, and we found an efficient fuel-oxidizer composed of potassium chlorate and thiocarbamide. Impressive bengal lights of various colors can easily be achieved using this basic composition.
