Abstract: A process for obtaining a material including a glass sheet, includes providing a glass sheet including a first face coated at least partly by an essentially mineral first coating, the face having at least one first zone and at least one second zone, the at least one first zone having a higher emissivity than that of the second zone, then applying, on at least one portion of the second zone, a sacrificial layer including a resin, then heat treating the coated glass sheet at a temperature of at least 550° C., during which step the sacrificial layer is removed by combustion.
