Boiling chips (one of the more common brands is Boileezer) should not be placed in a hot liquid since they may very rapidly start the liquid boiling. Boiling chips provide nucleation sites for gas bubbles to form in a hot liquid. They prevent the liquid from absorbing excess heat and spontaneously boiling all at once (called bumping). If you place a boiling chip in a hot liquid that is at its boiling point, it will spontaneously boil and could splash out of the heating vessel.
