Selective chemical fining of small bubbles in glass

A method of producing and fining glass, the method comprising:

• discharging combustion products from one or more submerged burners directly into a glass melt contained within an interior reaction chamber of a submerged combustion melter, the combustion products discharged from the one or more submerged burners agitating the glass melt;
• discharging foamy molten glass obtained from the glass melt out of the submerged combustion melter;
• supplying the foamy molten glass into a fining chamber of a fining vessel as input molten glass, the input molten glass combining with a molten glass bath contained within the fining chamber and introducing entrained bubbles into the molten glass bath, the input molten glass having a density and comprising up to 60 vol % bubbles;
• flowing the molten glass bath through the fining chamber in a flow direction, the molten glass bath having an undercurrent that flows beneath a skimmer, which is partially submerged in the molten glass bath, and through a submerged passageway defined in part by the skimmer;
• introducing one or more fining agents into the undercurrent of the molten glass bath directly beneath the skimmer from a dissolvable fining material component;
• and
• discharging output molten glass from the fining vessel, the output molten glass having a density that is greater than the density of the input molten glass and further comprising less than 1 vol % bubbles.
