High temperature and low pressure fining of submerged combustion or other glass

A method of producing glass, the method comprising:

• producing a volume of unfined molten glass in a submerged combustion melter which includes discharging combustion products from one or more submerged burners directly into a glass melt held within an interior reaction chamber of the submerged combustion melter;
• receiving an inflow of unfined molten glass from the submerged combustion melter and introducing the inflow of unfined molten glass into a fining tank that holds a molten glass bath having a depth, the fining tank having a vertically-elongated housing that defines an interior fining chamber in which the molten glass bath is contained, the housing of the fining tank having a height and a width, with the height of the housing being greater than the width of the housing, the inflow of unfined molten glass combining with the molten glass bath in the interior fining chamber of the fining tank;
• maintaining the interior fining chamber of the fining tank at a subatmospheric pressure;
• inductively heating the molten glass bath contained within the fining tank to maintain the molten glass bath at a temperature ranging from 1250° C. to 1650° C.;
• discharging an outflow of fined molten glass from the fining tank, the outflow of fined molten glass being drawn from the molten glass bath and having a lower volume percentage of entrained gas bubbles and a higher density than the inflow of unfined molten glass received into the fining tank, the outflow of fined molten glass being in the form of a plurality of discrete streams of fined molten glass;
• passing the outflow of fined molten glass through an ambient environment as the outflow of fined molten glass falls from the fining tank into a thermal conditioning tank through an open space that separates the fining tank and the thermal conditioning tank, the outflow of fined molten glass cooling down when exposed to the ambient environment;
• and
• introducing the outflow of fined molten glass into the thermal conditioning tank in which the outflow of fined molten glass combines with a flowing molten glass bath held within a conditioning chamber of the thermal conditioning tank.
