A process for manufacturing glass objects such as bottles, in which a cold fluid containing a cryogen is sprayed around and/or under the bottles in the region of the transfer tongs and/or of the standby table in order to accelerate the cooling of the bottles and improve the quality of the latter and the productivity of the manufacturing machines. This cooling may be accompanied by a localized, or complete quenching of the bottle.
