A method for manufacturing antimicrobial glass includes the steps of: a) providing a glass with alkali metal ions; b) placing the glass in a first oven to perform semi-physical strengthening and dealkalization; and c) placing the glass in a second oven to perform chemical strengthening.

The glass sheet of the present invention is a glass sheet with a thickness of 1.6 mm or less produced by a float process in which a molten glass material is formed into a sheet on a molten metal. When one surface of the glass sheet kept in contact with the molten metal during the formation of the molten glass material into the glass sheet is defined as a first surface and the other surface of the glass sheet opposite to the first surface is defined as a second surface, at least the first surface has been subjected to a treatment for forming a densified dealkalized layer therein. An etching rate ER.sub.1 (nm/min) of the first surface and an etching rate ER.sub.2 (nm/min) of the second surface satisfy a relation of ER.sub.2/ER.sub.10.8 when the first surface and the second surface are etched using 0.1 mass % hydrofluoric acid at 50 C. as an etching liquid.

A synthetic quartz glass substrate having a controlled hydrogen molecule concentration is prepared by (a) hot shaping a synthetic quartz glass ingot into a glass block, (b) slicing the glass block into a glass plate, (c) annealing the glass plate at 500-1,250 C. for 15-60 hours, (d) hydrogen doping treatment of the glass plate in a hydrogen gas atmosphere at 300-450 C. for 20-40 hours, and (e) dehydrogenation treatment of the glass plate at 200-400 C. for 5-10 hours.

A sterile glass pharmaceutical container or vessel such as, but not limited to, vials for holding pharmaceutical products or vaccines in a hermetic and/or sterile state. The sterile glass pharmaceutical 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 pharmaceutical 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 pharmaceutical container is guaranteed, thus eliminating any potential for violation of pharmaceutical integrity or sterility (such as stable cracks) in the glass packaging which are not easily identifiable in an otherwise seemingly intact pharmaceutical container.

Methods for manufacturing and/or reinforcing a carbon-containing glass material are disclosed. The method includes supplying a non-thermal equilibrium plasma including a plurality of positive charged gas particles and a plurality of ionized inert gas particles into a reaction chamber, and accelerating at least the plurality of positive charged gas particles through the reaction chamber based on application of an external electric potential to the non-thermal equilibrium plasma. The method includes bombarding a surface-to-air interface of the glass material with the accelerated positive charged gas particles and the ionized inert gas particles, and forming an interphase region in the glass material in response to the bombardment. The method includes forming a compressive stress layer in the glass material in response to the bombardment by at least the ionized inert gas particles. The compressive stress layer may be disposed between the interphase region and the surface-to-air interface of the carbon-containing glass material.

Provided herein are methods of heating and tempering glass using a microwave generator, such as a gyrotron. Also provided herein are systems comprising an microwave generator, such as a gyrotron, used to heat glass to a tempering temperature.

Glass-based articles that include a hydrogen-containing layer extending from the surface of the article to a depth of layer. The hydrogen-containing layer includes a hydrogen concentration that decreases from a maximum hydrogen concentration to the depth of layer. The glass-based articles exhibit a high Vickers indentation cracking threshold. Glass compositions that are selected to promote the formation of the hydrogen-containing layer and methods of forming the glass-based article are also provided.

Systems and methods for batch processing glass substrate webs are disclosed. In one embodiment, a method of processing a glass substrate web includes applying a spacer layer to at least one of a first surface or a second surface of the glass substrate web, and rolling the spacer layer and the glass substrate web to form a spool. The spacer layer is configured such that a gap exists between the first surface and the second surface of the glass substrate web within the spool. The method further includes applying a fluid to the spool such that the fluid surrounds the spool and is disposed within the gap between the first surface and the second surface within the spool.

Glass-based articles that include a compressive stress layer extending from a surface of the glass-based article to a depth of compression are formed by exposing glass-based substrates to water vapor containing environments. The glass-based substrates have compositions selected to avoid the formation of haze during the treatment process. The methods of forming the glass-based articles may include elevated pressures and/or multiple exposures to water vapor containing environments selected to avoid the formation of haze during the treatment process.
