Abstract
A sheet of molten glass issuing from an overflow channel is supplied to the molten metal bath used in the formation of float glass. The overflow channel is positioned adjacent one end of such bath transversely of the longitudinal extent thereof, and the overflow channel is fed at one end thereof with homogeneous glass which has been thoroughly stirred and homogenized within a forehearth immediately adjacent the inlet end of such overflow channel, so that the resulting sheet may be attenuated without detrimental surface streak or ridges due to internal striae or cord which detrimentally affect the optical quality of the sheet.
