Abstract
The present invention provides a method of melting glass, whereby in a glass melting furnace having electrodes positioned in a plurality of levels or planes the glass is melted in a vertical passage and thereafter discharged via an outlet passage at the bottom of the furnace, while the glass stream, after its upward flow, flows vertically downwards under mechanical agitation, thereafter to flow upwards for further processing or treatment. The glass stream may be additionally heated by electrical energy during its upward flow prior to the agitation.
