sciencemuseummn #FridayFun: The Chemistry of Fireworks.

Sodium produces yellow/gold colors. Barium creates green, copper compounds produce blue, strontium salts give you red and titanium metals give you silver colored sparks. Other commonly used chemicals are carbon, which provides the fuel, oxidizers which produce oxygen for burning, magnesium, which increases the overall brilliance and brightness, antimony that gives you a "glitter" effect and calcium which deepens the colors.
