    Abstract: A strengthened antimicrobial glass including greater from about 50.0 mol. % to about 65.0 mol. % SiO2, about 14.0 mol. % to about 22.0 mol. % Al2O3, about 14.0 mol. % to about 22.0 mol. % R2O, wherein R is an alkali metal, and about 4.0 mol. % to 10.0 mol. % P2O5. The glass may have a compressive stress layer having a thickness of greater than or equal to about 20 μm less than or equal to about 60 μm and having a compressive stress of greater than or equal to about 700 MPa. The glass may have an antimicrobial activity greater than or equal to about 1.0 log kill at about 23° C. and about 40.0% relative humidity. A method for making the glass may include obtaining a glass article, strengthening the glass article by contact with a first ion-exchange liquid, and contacting the glass article with second ion-exchange liquid comprising an antimicrobial agent.

    Abstract: An alkali aluminosilicate glass that can be chemically strengthened and formed into a three dimensional shape. The glass has a softening point of less than about 825° C. and a high temperature coefficient of thermal expansion of less than about 30 parts per million (ppm)/° C. The glass may be ion exchanged after the three dimensional shape is formed. When ion exchanged, the glass has a surface layer that is under a compressive stress of at least about 700 MPa.

    Abstract: A stack assembly including a glass element having a thickness of less than or equal to 200 microns, and a first layer supporting the glass element. The glass element having a first pen drop height value when directly adjacent on a solid aluminum stage. The first layer having a stiffness of from 9×105 N/m to 2.0×106 N/m. When the glass element is supported by the first layer on the aluminum stage, the glass element comprises a second pen drop height value, wherein the second pen drop height value is greater than the first pen drop height value.

    Abstract: Provided herein is a glass composition comprising: about 72 mol % to about 77 mol % SiO2; about 8 mol % to about 12 mol % Al2O3; about 10 mol % to about 14 mol % of one or more alkali oxide R2O, wherein R2O is Li2O, Na2O, K2O, Rb2O, or Cs2O; one or more divalent oxide RO, wherein RO is MgO, CaO, SrO, BaO, or ZnO; and P2O5, wherein the ratio of mol % RO/(mol % R2O+mol % RO) is at least about 0.2. The glass composition has one or more of the following characteristics: (i) a low temperature (form 25° C. to 300° C.) coefficient thermal expansion (LTCTE) of less than 7.5 ppm/° C.; (ii) high temperature coefficient thermal expansion (HTCTE) of less than 18 ppm/° C.; (iii) liquidus viscosity of at least 200,000 poise; (iv) glass temperature of at least 1100° C. at 200,000 poise or at least 1200° C. at 35,000 poise; and (v) a fictive temperature Tf less than about 795° C.
