Incendiary bombs are of two main types. The burning material of the intensive type is thermite, a mixture of aluminium powder and iron oxide that burns at a very high temperature. The casing of such a bomb is composed of magnesium, a metal that itself burns at a high temperature when ignited by thermite. Intensive-type incendiaries are designed to set buildings afire by their intense heat. The other type of incendiary bomb is a thin-walled container of napalm, or jellied gasoline, that is used against personnel, vehicles, and flammable installations. The napalm spreads over a wide area, sticks to whatever it falls upon, and burns for a long time.
