Glass plates are thermally or chemically tempered to increase flexural bending strength. The tempered plates are subsequently subjected to a heat treatment in order to lower the possibility of spontaneous breakage of the glass plates. According to the method according to the invention the glass plates are tempered at least twice and again heat-treated. At least the second heat treatment takes place at higher temperatures than were used previously. The treated glass plates have increased flexural bending strength and reduced tendency to spontaneous breakage.

Afin de renforcer leur résistance à la flexion et à la rupture par traction, des plaques de verre sont précontraintes thermiquement ou chimiquement. Afin d'éviter l'apparition de ruptures spontanées des plaques de verre, lesdites plaques précontraintes sont ensuite soumises à un traitement thermique. Selon le procédé mis au point, les plaques de verre sont précontraintes au moins une seconde fois, puis sont à nouveau soumises à un traitement thermique. Ce second traitement thermique intervient à des températures plus élevées que celles jusqu'alors en usage. Les plaques de verre traitées présentent une meilleure résistance à la flexion et à la rupture par traction et une tendance moins prononcée aux ruptures spontanées.
