You can find out the identity of an unknown element by analyzing the color of its flame. All the elements give off different colored flames when burned. Using a spectrometer you can analyze a compound and find out what it is made of.

Coloured fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame red, orange, yellow, or white, and is dominated by blackbody radiation from soot and steam. When additional chemicals are added to the fuel burning, their atomic emission spectra can affect the frequencies of visible light radiation emitted - in other words, the flame will appear a different colour dependant upon the chemical additives.
Pyrotechnicians will generally use metal salts to colour their flames. Specific combinations of fuels and co-solvents are required in order to dissolve the necessary chemicals. Colour enhancers are frequently added too, the most common of which is polyvinyl chloride.
