Abstract: A soda-lime-silica glass container and related methods of manufacturing. A black-strikable glass composition having a base glass portion and a latent colorant portion is prepared. The base glass portion includes soda-lime-silica glass materials and one or more blue colorant materials, and the latent colorant portion includes cuprous oxide (Cu2O), stannous oxide (SnO), bismuth oxide (Bi2O3), and carbon (C). Glass containers may be formed from the black-strikable glass composition, and these glass containers may be heated to a temperature greater than 600 degrees Celsius to strike black therein. The glass containers formed from the black-strikable glass composition may be inspected—before or after striking—by infrared inspection equipment.

Abstract: A glass container and a process for chemically modifying a surface portion of a glass container using an ion-exchange process. At least a portion of the glass container is immersed in or in contact with an aqueous electrolyte solution comprising salts of at least one group IA alkali metal and having a temperature of about 75 degrees Celsius such that exchangeable alkali metal ions in a surface portion of the glass container are exchanged or replaced by alkali metal ions in the electrolyte solution. The alkali metal ions that replace the exchangeable ions in the surface portion of the glass container have either a smaller or a larger atomic radius than the exchangeable ions.

Abstract: A process for cullet beneficiation by precipitation. A mass of cullet is melted to form a body of molten glass having a heavy metal con ration of greater than 100 ppm. A precipitate agent is introduced into the body of molten glass to form a heavy metal-containing precipitate phase and a liquid beneficiated glass phase within the body of molten glass. The precipitate phase may have a density greater than that of the liquid beneficiated glass phase. Thereafter, the liquid beneficiated glass phase is physically separated from the precipitate phase. The separated liquid beneficiated glass phase has a reduced concentration of heavy metals, as compared to the concentration of heavy metals in the body of molten glass.

Abstract: A method of making a glass container with an optically readable graphic data carrier. A glass container is exposed to electromagnetic radiation to produce discoloration within the glass of the container, and then focused beam energy is directed at the glass container in a pattern corresponding to a desired graphic data carrier to heat the glass and selectively remove the discoloration in the pattern corresponding to the desired graphic data carrier.

Abstract: A glass container and a process for forming an inorganic silica coating on an exterior surface of the glass container to improve one or more surface characteristics of the glass container. A sol-gel solution including a polysilazane and an organic solvent is applied to the exterior surface of the glass container to form a sol-gel coating thereon. The glass container and the sol-gel coating are then exposed to a water vapor-containing environment and heated at a temperature of between 150 degrees Celsius and 600 degrees Celsius to transform the sol-gel coating into an inorganic silica coating. The as-formed silica coating has a hardness of greater than 8.5 GPa and is bonded to the exterior surface of the glass container through a plurality of siloxane bonds.

Abstract: A glass container and related methods of manufacturing a glass container. A solution having a composition including a silane, a solvent, a catalyst, and water, is applied to an exterior glass surface of the glass container, at a temperature between 40 and 60 degrees Celsius, such that the solution at least partially fills the surface imperfections.
