Abstract
Procedure to improve the mechanical resistance of glass objects, characterized in that it consists of first tempering the glass object, bringing it to a temperature close to the softening point and then subjecting it to sudden cooling to the temperature of tension, eventually below the itself, and then in providing the outer layers of the glass with a heat flow sufficiently intense to generate in these outer layers, by thermal expansion, contractions capable of causing their sliding in relation to the relatively more rigid inner layers, these layers not being internal temperatures brought to a temperature significantly higher than the voltage temperature, due to the shortness of the heat flow.
