A soda-lime-silica glass that has a composition comprising 60-80 wt % SiO; 8-18 wt % NaO; 5-15 wt % CaO; 0-3 wt % AlO; 0.0010-0.050 wt % silver expressed as AgO; and 0.005-0.30 wt % bismuth expressed as BiOis 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.

Yellow soda-lime-silica glass

A process for transitioning molten glass in a glass furnace from one color to another color while minimizing the production of out-of-color specification transition glass. During the transition, a compensating agent is introduced into the molten glass to adjust the color of the molten glass being discharged from the furnace so that the discharged molten glass meets a target color specification, which effectively results in acceleration of the furnace color change compared to other conventional methods.

Method and system for manufacturing glass

A glass refining system, glass refining device, and method are disclosed. The apparatus in accordance with one aspect of the disclosure includes an objective having a laterally outer extremity, where a molten metal stream flows from an opening in the objective and over the objective, and separates from the objective at a molten metal separation location that is inboard of the extremity; and a molten metal receptacle disposed below the objective and configured to receive the molten metal stream, wherein a molten glass stream flows downwardly toward the objective and over the molten metal stream, and wherein the molten glass stream separates from the molten metal stream at a molten glass separation location that is laterally outboard of the molten metal separation location and flows into a molten glass receptacle.

Glass fining using an objective and molten metal

In a process for manufacturing glass, a mixture of solid glass-forming materials may be melted by application of heat from one or more submerged combustion burners to produce a volume of unrefined molten glass comprising, by volume, 20% to 40% gas bubbles. A refining agent may be introduced into the unrefined molten glass to promote gas bubble removal from the molten glass. The unrefined molten glass including the refining agent may be heated at a temperature in the range of 1200&#xb0; C. to 1500&#xb0; C. to produce a volume of refined molten glass. The refined molten glass may comprise, by volume, fewer gas bubbles than the unrefined molten glass. A colorant material may be introduced into the refined molten glass to produce a volume of molten glass having a final desired color.
