Electrode for a glass melting furnace which avoids the disadvantages of known electrodes which are either expensive and difficult to manufacture, or have operational disadvantages, especially in regard to the delivery of electric power into the molten glass and/or in regard to trouble-free useful life. The new electrode is less costly to make and has better operational properties. The electrode shaft 2 is a coaxial tube 20 with an inner tube 21 of a metal constituting a good electrical conductor, preferably copper, and with the outer tube 22 of a mechanically strong, heat-resistant metal, preferably steel. Moreover, the electrode body 3 can be made thicker in areas of intense corrosion. The new electrode is suitable for all glass melting furnaces which are partially or entirely heated with electricity.
