Abstract: 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.

Abstract: Prism coupling systems and methods for characterizing curved parts are disclosed. A coupling surface of a coupling prism is interfaced to the curved outer surface of the curved part to define a coupling interface. Measurement light is directed through the coupling prism and to the interface, wherein the measurement light has a width of 3 mm or less. TE and TM mode spectra reflected from the interface are digitally captured. These mode spectra are processed to determine at least one characteristic of the curved part, such as the stress profile, compressive stress, depth of layer, refractive index profile and birefringence.

Abstract: Intermediate to high CTE glass compositions and laminates formed from the same are described. The glasses described herein have properties, such as liquidus viscosity or liquidus temperature, which make them particularly well suited for use in fusion forming processes, such as the fusion down draw process and/or the fusion lamination process. Further, the glass composition may be used in a laminated glass article, such as a laminated glass article formed by a fusion laminate process, to provide strengthened laminates via clad compression as a result of CTE mismatch between the core glass and clad glass.

Abstract: A strengthened glass container or vessel such as, but not limited to, vials for holding pharmaceutical products or vaccines in a hermetic and/or sterile state. The strengthened glass container undergoes a strengthening process that produces compression at the surface and tension within the container wall. The strengthening process is designed such that the tension within the wall is great enough to ensure catastrophic failure of the container, thus rendering the product unusable, should sterility be compromised by a through-wall crack. The tension is greater than a threshold central tension, above which catastrophic failure of the container is guaranteed, thus eliminating any potential for violation of pharmaceutical integrity.
