Fireworks light up the sky during celebrations; they give a wonderful show of color and shapes that fascinate the eyes and minds of many. The beauty of the display often leads many to wonder where the colors come from. The short answer is that they are the result of the burning of metals placed in these explosives. These metals are elements of the periodic table that burn at different temperatures and give off colors at their melting points.
Red displays come from Lithium, Rubidium and Strontium. These metals give different intensities in color and some even play other roles. Lithium and Rubidium are metals in group one of the periodic table. Lithium gives a medium red color and is most useful, for this purpose in its carbonate form. Rubidium on the other hand gives a deep red/ violet-red flame and is also used to oxidize the mixtures in these explosives; without oxidation, they will not burn properly. Strontium burns with an intense red but it also has the job of stabilizing the elements used to make the fireworks.
