Mechanisms of heat transfer need to be understood to control plasma more efficiently in industrial applications. Floating potential is defined to be the potential on molten 25 mol%Na2O-SiO2 glass surface and the dependence of transferred-type thermal plasma current on the floating potential of the glass has been studied using the Langmuir probe method. An anomalous probe voltage–current curve was found when the plasma current was applied under 3 A. It is also considered that the electrochemical reaction at the surface exists, which is dependent on the plasma current.
