Abstract
A process for the manufacture of a heat strengthened glass substrate, includes the application of a temporary layer including a polymer on a glass substrate including a glass sheet, then the application to the glass substrate coated with the temporary layer of a treatment for the heat strengthening of the glass including heating, leading to the removal of the temporary layer, and then cooling by blowing of air through nozzles. The glass substrate thus obtained exhibits a reduced level of iridescences.
