1. A process for melting glass in a horseshoe-flame furnace including a rear, a forward and a lateral wall and a longitudinal axis comprising the steps of:

  • introducing a charge into a region of the rear wall of the furnace;

    running said charge, in succession in a longitudinal direction, through a melting zone to completely melt said charge and form a glass bath, through a homogenization zone and then through a refining zone;

    evacuating the melted and refined glass into a region of the forward wall of the furnace;

    sending an air-fuel flame from a first region in said rear wall which is staggered with respect to said longitudinal axis of the furnace,evacuating smoke from a second region of the rear wall essentially symmetrically to the first region with respect to said axis;

    periodically alternating operation of said first and second regions; and

    sending at least one oxy-fuel flame contained above said refining zone from a point on the lateral wall adjacent to said second region which is situated opposite said refining zone.
