Abstract
In glass tempering using a cooling gas, the impact of gas jets on glass is modified through the use of perturbations to which said jets are subject. The perturbations may be introduced laterally with respect to the tempering jets, and spaced from the opening providing said tempering jets. The characteristics of the perturbations vary cyclically. The invention makes it possible to obtain homogeneous tempering, even for highly bulged glass sheets.
