| 1. A glass-melting furnace comprising:
an elongated channel consisting of a charge end wall, a discharge end wall, two side walls, a floor, and a roof, the elongated
channel defining an upstream melting end, a downstream fining end through which molten glass is discharged, the upstream end
being positioned upstream of the downstream end in the glass-melting furnace;
a charger supplying glass-forming material to the upstream end of the glass-melting furnace;
at least one burner supplying at least a majority of the heat to the glass-forming material at the upstream end of the glass-melting
furnace;
the upstream end and the downstream end being configured to allow unimpeded flowing and blending of the glass-forming material;
and
an exhaust disposed within the downstream end of the glass-melting furnace for exhausting combustion gases only from the downstream
end of the glass-melting furnace, the exhaust further being positioned downstream of the at least one burner;
the exhaust disposed for allowing exhaust gases to provide additional heat to the melting glass-forming material, and for
allowing at least some air-entrained glass-forming materials to scale back into the melting glass as exhaust gases travel
from the upstream end to the downstream end.
