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.

Latent colorant material compositions, soda-lime-silica glass compositions, and related methods of manufacturing color-strikable glass containers. The latent colorant material compositions may be introduced into a plurality of base glass compositions having redox numbers in the range of &#x2212;40 to +20 to produce color-strikable glass compositions and color-strikable glass containers. The latent colorant material compositions introduced into the base glass compositions include a mixture of cuprous oxide (CuO), stannous oxide (SnO), bismuth oxide (BiO), and carbon (C). After formation, the color-strikable glass containers may be heat-treated to strike red or black therein.

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.

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.
