Abstract
There is provided an apparatus and method for detecting molten salt in molten metal. A pair of electrically conductive probes are immersed in the molten metal. The probes are connected to an electrical circuit which includes a voltage source and a current detector. The entire immersed portion of one of the probes is coated with an electrically nonconductive porous material which is wetted by molten salt but is not wetted by molten metal. If molten salt is present, the circuit will be completed and a substantial electrical current will flow between the probes, which current is detected by the current detector. If no salt is present, the circuit will not be completed and essentially zero current will be detected.
