Abstract

Procedure for the treatment of vitreous or partially vitreous bodies, in a gas-filled treatment chamber, in at least one area of which the temperature of at least one face of said body is at, or acquires a temperature that is sufficiently high for the configuration of that face to be influenced by the distribution of heat in the gaseous atmosphere of that area, characterized in that gas displacing forces are exerted first in one direction and then in an inverse direction to make the gas of at least such a zone moves back and forth in contact with said face while its temperature, in that zone, remains at said value.
