A method of thermally tempering a glass sheet. The method includes preheating the glass sheet to a temperature higher a strain point of the glass sheet and lower than a softening point of the glass sheet, exposing the glass sheet to a beam of penetrating microwave radiation in order to heat the mid-plane of the glass sheet to a temperature that is above the softening point while simultaneously keeping a surface of the glass sheet at a temperature that is below the softening point, and quenching the glass sheet so that the temperature of the mid-plane and the surface of the glass sheet fall below the strain point, respectively. |
