A continuous ribbon of glass is reduced in thickness while supported on molten metal by imposing super-atmospheric pressure over a molten glass layer in a chamber where the glass is maintained in contact with the side walls of the chamber. One aspect features metering the glass layer into the pressure chamber at substantially full width. Another aspect involves pressure sizing the glass layer at temperatures above 2100 DEG F. (1150 DEG C.). |
