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)
We summarised some of the different compounds that can be used for this purpose in the older post on the colours of fireworks. Of course, the metal powder and the oxidiser would be useless without a way to bind them together into a paste that can then be added onto the metal rod that forms our sparkler.e summarised some of the different compounds that can be used for this purpose in the older post on the colours of fireworks.
