Methods and systems produce a molten mass of foamed glass in a submerged combustion melter (SCM). Routing foamed glass to a fining chamber defined by a flow channel fluidly connected to and downstream of the SCM. The flow channel floor and sidewalls have sufficient glass-contact refractory to accommodate expansion of the foamed glass as fining occurs during transit through the fining chamber. The foamed glass is separated into an upper glass foam phase and a lower molten glass phase as the foamed glass flows toward an end of the flow channel distal from the SCM. The molten glass is then routed through a transition section fluidly connected to the distal end of the flow channel. The transition section inlet end construction has at least one molten glass inlet aperture, such that the inlet aperture(s) are positioned lower than the phase boundary between the upper and lower phases.
