Applications of the Flame test?

I already know coloring fire is used in fireworks, and to decorate fires obviously... if you know of any other applications can you please say them thanks!

Many street lamps and halogen lights work by the same mechanism (there's no flame, but the principle is identical. Excite the electrons, light is emitted when they relax.) The characteristic yellow glow of many street lamps is due to sodium.

One of the chemistry related applications is that using specialised equipment, rather than carrying out the flame test in the 'normal' way by just looking at it, you can calculate the concentration of a metal in a particular compound or solution. This is known as AES or Atomic Emission Spectroscopy.

A commonly referenced practical use of this is to determine the concentration of different metals in drinking water. Many metals, such as lead, are toxic but can get into water supplies quite easily (lead pipes) so concentrations can be monitored to check the water is safe.

A related technique is Atomic Absorption Spectroscopy, which works on the same basis except that light is absorbed rather than emitted (as the name suggests). This is somewhat more sensitive and can detect some metals down to nano-molar concentrations.
