1. Apparatus for the melting and fining of glass comprising a receptacle for containing glass constituents including molten glass up to a glass line and glass batch above portions of said glass line;

  • a first region in said receptacle adapted to receive glass batch;

    a second region in said receptacle spaced horizontally from said first region and adapted to have molten glass withdrawn therefrom;

    a heat source beneath the glass line in said first and second regions adapted to heat the glass;

    means for distributing glass batch as a blanket over a preponderance of the upper surface of said first region;

    a heat source beneath the glass line adapted to heat the glass; and

    a cover for said receptacle to enclose the space above said second region, said cover having a flue for the passage of gas from beneath said cover and said cover being positioned sufficiently close to said glass line so as to reflect heat from within the glass in said second region back to the exposed upper surface of the glass in said second region to increase the fluidity of said surface to an extent to facilitate the escape of gas from said surface in said second region while thermal conditions at the exposed surface of said first region maintain a batch blanket over a preponderance of the upper surface of said first region.
