That means that the different types of metals used in the stars each have a characteristic color. Here are some of the metals and specific compounds that are typically used in fireworks to produce different colors: Red: strontium (strontium carbonate, SrCO3), for intense reds and lithium (lithium carbonate, Li2CO3, or lithium chloride, LiCl) for medium reds. Orange: calcium (calcium chloride, CaCl2)
The heat of the metal determines the color of the sparks. Lithium-Lithium is a metal that is used to impart a red color to fireworks. Lithium carbonate, in particular, is a common colorant. Magnesium-Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework.Oxygen-Fireworks include oxidizers, which are substances that produce oxygen in order for burning to occur. The oxidizers are usually nitrates, chlorates, or perchlorates.he heat of the metal determines the color of the sparks. Lithium-Lithium is a metal that is used to impart a red color to fireworks.
