Abstract
An electric furnace for heating glass by the Joule effect comprising: a chamber adapted for holding a body of molten glass; a plurality of electrodes positioned in the chamber such that the electrodes form a zone with two clusters of electrodes in the zone, the clusters being located on opposite sides of the chamber, each of the clusters comprising first and second sets of electrodes, the first set being positioned closer to the other cluster than the second set and the first and second sets being positioned such that the second set of electrodes carries at least 60% of the current carried by the first set; and a source of power connected to the clusters.
