Atoms - universe-review Contents
A crude and cheap method to detect metal ions is the flame test, which heats the sample on a loop of platinum wire moistened with hydrochloric acid (HCl) in a colorless flame. Figure 13-01f shows the color of the flame from sodium carbonate (Na 2 CO 3 4).
In flame tests, salts that are dissolved in water are evaporated using a hot flame. In the flame, the metal atoms become excited and produce their characteristic spectrum of light. However, since the observer does not use a spectroscope only one color is observed.

Borax - Wikipedia
When borax is added to a flame, it produces a yellow green color. Borax is not used for this purpose in fireworks due to the overwhelming yellow color of sodium. Boric acid is used to color methanol flames a transparent green.
flame test | Infoplease
flame test, test used in the identifiion of certain metals. It is based on the observation that light emitted by any element gives a unique spectrum when passed through a spectroscope. When a salt of the metal is introduced into a Bunsen burner flame, the metallic ion produces characteristic color in the flame.
