Inspectable Black Glass Containers
First Claim
1. A method of inspecting a black glass container for commercial variations that affect optical characteristics of the glass container, the method including the steps of:
- directing infrared light energy onto the black glass container; and
receiving infrared light energy from the black glass container on an infrared light sensor, the infrared light sensor being responsive to infrared light energy having wavelengths in the range of 750 nm to 1100 nm.

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.
