Producing flint glass using submerged combustion melting

A method comprising:

• introducing a vitrifiable feed material into a glass melt contained within a submerged combustion melter, the submerged combustion melter comprising one or more submerged burners and the vitrifiable feed material being formulated to provide the glass melt with a soda-lime-silica flint glass chemical composition that includes 60 wt % to 80 wt % SiO2, 8 wt % to 18 wt % Na2O, 5 wt % to 15 wt % CaO, and 0 wt % to 2 wt % Al2O3;
• discharging combustion products from the one or more submerged burners directly into the glass melt, the one or more submerged burners combusting a combustible gas mixture that comprises fuel and oxygen, wherein an oxygen-to-fuel ratio of the combustible gas mixture ranges from stoichiometry to 30% excess oxygen relative to stoichiometry;
• maintaining a temperature of the glass melt between 1200° C. and 1500° C. and a residence time of the glass melt between 1 hour and 10 hours;
• and
• discharging a flint molten glass from the submerged combustion melter at a specific throughput rate that ranges from 2 tons per day per meter squared of cross-sectional area of the submerged combustion melter [tons/day/m2] to 25 tons/day/m2, wherein the flint molten glass discharged from the submerged combustion melter has a density of 0.75 gm/cm3 to 1.5 gm/cm3;
• and
• refining the flint molten glass discharged from the submerged combustion melter to obtain a refined molten glass, the refined molten glass having a density that ranges from 2.3 gm/cm3 to 2.5 gm/cm3.

A method comprising:

• introducing a vitrifiable feed material into a glass melt contained within an interior reaction chamber of a submerged combustion melter, the submerged combustion melter comprising one or more submerged burners;
• discharging combustion products from the one or more submerged burners directly into the glass melt, the one or more submerged burners combusting a combustible gas mixture that comprises fuel and oxygen, and wherein an oxygen-to-fuel ratio of the combustible gas mixture ranges from stoichiometry to 30% excess oxygen relative to stoichiometry;
• maintaining a temperature of the glass melt between 1200° C. and 1500° C.;
• maintaining a residence time of the glass melt between 1 hour and 10 hours;
• discharging a flint molten glass from a molten glass outlet of the submerged combustion melter at a specific throughput rate that ranges from 2 tons per day per meter squared of cross-sectional area of the interior reaction chamber at a height of the molten glass outlet [tons/day/m2] to 25 tons/day/m2;
• and
• forming a glass container from the flint molten glass, wherein the glass container, when solidified, is visually transparent as demonstrated by a dominate wavelength between 572 nm and 578 nm, a brightness above 50%, and a purity below 16%.
