wherein surface fictive temperature measured on the first major surface is at least 50° C. above a glass transition temperature of the glass of the glass sheet;
wherein an average thickness between the first and second major surfaces is less than 2 mm;
wherein an ion content and chemical constituency of at least a portion of both the first major surface and the second major surface is the same as an ion content and chemical constituency of at least a portion of the interior region;
wherein the first and second major surfaces are under compressive stress greater than 150 MPa and at least a portion of the interior region is under tensile stress;
wherein a surface roughness of the first major surface is between 0.2 and 1.5 nm Ra roughness.
