Abstract

"Glass melting procedure and furnace", in which a tank formed by a refining melting zone and a conditioning zone (paste) inside which currents exist in the mass of melted glass, which surface move away from the hottest point of the fusion zone (flow current) and in depth they converge towards this zone (return current), characterized by the fact that certain veins are bounced from the middle part of the flow current to that it is again taken up by the return stream and takes it back to the melting zone, the passage of the lateral veins of the outward flow towards the lower zone of the furnace that remains absolutely free.
