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)
Here's an element-by-element look at what is involved in your average firework: Aluminum-Aluminum is used to produce silver and white flames and sparks. It is a common component of sparklers. Antimony-Antimony is used to create firework glitter effects.Barium-Barium is used to create green colors in fireworks, and it can also help stabilize other volatile elements. Calcium-Calcium is used to deepen firework colors.ulfur-Sulfur is a component of black powder. It is found in a firework's propellant/fuel. Strontium-Strontium salts impart a red color to fireworks. Strontium compounds are also important for stabilizing fireworks mixtures. Titanium-Titanium metal can be burned as powder or flakes to produce silver sparks.
