Shown above are results of a flame test, a procedure in chemistry in which a hot, non-luminous flame (typically a Bunsen burner) is exposed to a sample of an element or compound to detect the presence of various metal ions, which give off very specific characteristic colors based on an emission spectrum unique to every element. The elements shown from left to right are as follows: Barium, Potassium, Strontium, Calcium, and Sodium.
