A laminated glass article includes a core layer and a clad layer directly adjacent to the core layer. The core layer is formed from a core glass composition. The clad layer is formed from a clad glass composition. An average clad coefficient of thermal expansion (CTE) is less than an average core CTE such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer decreases with increasing distance from an outer surface of the clad layer within an outer portion of the clad layer and remains substantially constant with increasing distance from the outer surface of the clad layer within an intermediate portion of the clad layer disposed between the outer portion and the core layer. A thickness of the intermediate portion of the clad layer is at least about 82% of a thickness of the clad layer.

A method of making a glass sheet comprises laminating a high CTE core glass to a low CTE clad glass at high temperatures and allowing the laminate to cool creating compressive stress in the clad glass, and then ion exchanging the laminate to increase the compressive stress in the outer near surface regions of the clad glass. The core glass may include ions that exchange with ion in the clad glass to increase the compressive stress in inner surface regions of the clad glass adjacent to the clad glass/core glass interfaces. The glass laminate may be formed and laminated using a fusion forming and laminating process and fusion formable and ion exchangeable glass compositions.

An aluminoborosilicate glass includes alkaline earth oxides and is substantially free of alkali oxides. The glass may be fusion formable and may be useful as a substrate or other article, such as with consumer and commercial electronic devices.

A tinted glass composition and glass article including the same, the composition including: about 45 mol % to about 80 mol % SiO.sub.2; about 6 mol % to about 22 mol % Al.sub.2O.sub.3; 0 mol % to about 25 mol % B.sub.2O.sub.3; about 7 mol % to about 25 mol % of at least one alkaline earth oxide selected from MgO, CaO, SrO, BaO, and combinations thereof; about 0.5 mol % to about 20 mol % CuO; 0 mol % to about 6 mol % SnO.sub.2, SnO, or a combination thereof; 0 mol % to about 1.0 mol % C; 0 mol % to about 5 mol % La.sub.2O.sub.3; and 0 mol % to about 10 mol % PbO, and that is substantially free of alkali metal.

A method includes heating a glass preform having a plurality of glass layers and drawing the glass preform in a distal direction to form a drawn glass sheet extending distally from the glass preform and having the plurality of glass layers. The drawn glass sheet is thinner than the glass preform. The drawn glass sheet can be rolled onto a collection spool. At least a portion of a glass layer can be removed from the drawn glass sheet. An exemplary glass sheet includes a first glass layer, a second glass layer adjacent to the first glass layer, and a thickness of at most about 0.1 mm. An exemplary ion exchanged glass sheet includes a thickness of at most about 0.1 mm and a surface layer that is under a compressive stress and extends into an interior of the glass sheet to a depth of layer.
