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.
