Abstract

The invention relates to thermal quenching or tempering of glass by means of a gaseous jet directed by nozzles. According to the inventive method, the nozzles are supplied with gas and liquid under a pressure which enables the jet velocity attained at the exit of the nozzles to be at least sonic, said jet being comprised of a mixture of a gas and a finely divided liquid. In particular the gas may be air and the liquid water. The invention may be applied to vertical or horizontal quenching or tempering of sheets or other items of glass.
