Borax bead test is used to identify the present metal in given salt or mineral. The chemical formula of borax is Na2B4O7 .10H2O.
To perform the test a small loop is formed at the end of a platinum wire. The loop is cleaned with concentrated hydrochloric acid and dipped in powdered borax, then heated in the flame of a Bunsen burner until the borax melts, forming a bead. The bead is dipped into a tiny amount of the compound to be tested and is reheated in the flame.
