State whether the following is true or false.
Tempered glass can be cut to size after treatment.

  • A.True
  • B.False
  • C.True only at large scales
  • D.False only at small scales

Answer: B

The compressive surface layer stores energy, and breaking through it destroys the whole pane. This is why every hole and edge must be finished before the sheet goes into the tempering furnace. Any later cut destroys the whole pane at once.
