Abstract
Method of and apparatus for supplying streams of molten glass including: a feeder with a chamber having an opening for supply of glass marbles for conversion to a molten body; a bottom wall for the chamber having orifices for discharging the molten glass as streams; means for heating the feeder; and a surface above the molten glass effective to reflect radiation so that reflected radiation is concentrated in a chamber where unmelted glass is present during melting.
Claims6
A feeder for supplying molten glass comprising:
- a. sidewalls;
- b. a bottom wall having at least one orifice for discharging molten glass;
- c. a resistance element within said feeder to convert unmelted glass to a molten condition;
- d. a top wall adapted to reflect vertically upwardly moving heat from molten glass in said feeder to a single focal point in said feeder above said resistance element;
- and,
- e. conduit means for introducing unmelted glass into said feeder.

The method of supplying streams of molten glass comprising:
- a. introducing unmelted glass into a feeder having a bottom wall which has orifices through which streams of molten glass are discharged;
- b. heating said unmelted glass with a resistance element positioned within said feeder to form a body of molten glass;
- and,
- c. reflecting vertically upwardly moving heat from one or a plurality of walls of said feeder to concentrate said heat at a single focal point positioned in said feeder above said resistance element.
