ABSTRACT:
A forehearth for a glass furnace includes a roof having a plurality of longitudinal ridges depending therefrom. These define a central longitudinal channel lengthwise of which a current of cooling air flows between inlet and outlet ports to cool the central, hottest portion of the current of glass in the forehearth, and side channels which, optionally with burners or heaters, serve to reheat the portions of the glass current at the longitudinal edges of that current.
