An electrode 10 for heating a glass mass by passing electric current through it comprises a rod shaped body which is adapted to be passed through the wall 20 of a feeder or the like. The inner end 11 of the electrode, which protrudes into the glass mass, consists of molybdenum whereas at least a part 12 of the outer electrode portion, which is subjected to very elevated temperatures in air when the inner end 11 is in the glass mass, consists of molybdenum disilicide, MoSi2. <IMAGE> |
