Abstract: A transparent laminate is provided that includes at least one chemically prestressed pane having a thickness, a compressive stress (CS) of a surface layer, a thickness of the prestressed surface layer and a tensile stress (CT) of an interior portion. The tensile stress (CT) is greater than 0 and is less than the compressive stress divided by 50.
