ABSTRACT:
The invention relates to a process for melting glass forming ingredients in a glass melting furnace adapted therefore, said furnace having an upstream melting zone and a downstream fining zone, wherein the glass forming ingredients introduced to the upstream melting zone via inlet means and the resulting melt therefrom travel along a path from the melting zone to the fining zone, said melt being withdrawn from outlet means which communicate with the fining zone, the improvement comprising; providing at least one high momentum oxygen-fired flame in the vicinity of said outlet means to sweep unmelted glass forming ingredients floating on the surface of the melt in said vicinity to prevent said unmelted glass forming ingredients from entering the outlet means whereby the contamination of an outflowing molten glass from said outlet means is avoided or reduced.
