    Abstract: A glass that is ion exchangeable to a depth of at least 20 μm (microns) and has a internal region having a tension of less than or equal to 100 MPa. The glass is quenched or fast cooled from a first temperature above the anneal point of the glass to a second temperature that is below the strain point of the glass. In one embodiment, the glass is a silicate glass, such as an alkali silicate glass, an alkali aluminosilicate glass, an aluminosilicate glass, a borosilicate glass, an alkali aluminogermanate glass, an alkali germanate glass, an alkali gallogermanate glass, and combinations thereof.

    Abstract: An alkali aluminosilicate glass that is chemically strengthened and has a down-drawable composition. The glass has a melting temperature less than about 1650° C. and a liquidus viscosity of at least 130 kpoise and, in one embodiment, greater than 250 kpoise. The glass undergoes ion exchange at relatively low temperatures to a depth of at least 30 μm.

    Abstract: A process for making glass sheet with low compaction suitable for high temperature applications, such as low-temperature polysilicon-based TFT displays, and glass sheets thus made. The glass sheet desirably has an anneal point of at least 765° C., a CTE at most 42×10−7/° C. The process involves cooling the glass melt form a temperature corresponding to a viscosity of 1.0×1010 poise to a temperature corresponding to a viscosity of 1.0×1015 poise at a cooling rate CR, where CR≧5° C./second. The absolute value of the measured compaction of the glass sheet desirably is at most 175 ppm upon being re-heated to 675° C. for a period of time.
