Abstract
A glass sheet is cut while at a temperature at about its annealing point temperature by scoring the glass sheet along a line of cut and imparting a bending moment to the glass along the scored line to open the glass. The glass sheet remains at its elevated temperature throughout the cutting operation to reduce or eliminate additional heating required for subsequent processing.
