Abstract
A soda-lime-silica glass that has a composition comprising 60-80 wt % SiO2; 8-18 wt % Na2O; 5-15 wt % CaO; 0-3 wt % Al2O3; 0.0010-0.050 wt % silver expressed as Ag2O; and 0.005-0.30 wt % bismuth expressed as Bi2O3 is disclosed. Light-scattering silver colloids are dispersed throughout the soda-lime-silica glass to provide the glass with a yellow coloration. The soda-lime-silica glass may be in the form of a body that provides a shape of a container that defines an internal containment space. The body of such a container includes a base, a mouth that defines an opening to the internal containment space, and a wall that externs from the base to the mouth. A method of making a glass container that exhibits a yellow coloration is also disclosed.
