Abstract Glass sheets are shaped while heat-softened by engaging a surface thereof against an apertured surface of a vacuum mold within a heating fur- nace. After releasing the glass sheet for further processing, the vacuum mold is removed from the furnace without the glass sheet for cooling and returned to the furnace in sufficient time to engage the next glass sheet to be shaped. This invention avoids the need to overheat the glass to com- pensate for cooling that occurs when a mold engages a glass sheet outside a furnace to shape the latter without losing control of the maximum tempera- ture to which the mold is subjected during a glass sheet shaping program.
