Fireworks use different chemical salts to produce various colors when ignited. Barium, calcium, potassium, sodium, lithium, strontium, copper and chromium salts are commonly used to generate the golden sparkles seen in fireworks displays. The colors result from the excitation and de-excitation of electrons in the atoms of the burning salts.
