Abstract
Official abstract text for this publication.
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 (Cu 2 O), stannous oxide (SnO), bismuth oxide (Bi 2 O 3 ), 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of making glass containers including the steps of: preparing a black-strikable glass composition formulated to produce blue glass, which upon heat treatment and striking, develops a visually black color, the black-strikable glass composition having a base glass portion and a latent colorant portion, the base glass portion including 60-75 wt. % SiO 2 , 7-15 wt. % Na 2 O, 6-12 wt. % CaO, 0.1-3.0 wt. % Al 2 O 3 , 0.0-2.0 wt. % MgO, 0.0-2.0 wt. %…
