Claim 8:
9. A system for producing glass, the system comprising:
a stilling vessel that includes a stilling tank and a feeding spout, the stilling tank having a housing formed of a refractory material that is not fluidly cooled and that defines a stilling chamber, an inlet, an outlet, and one or more non-submerged burners aimed to discharge combustion products into the stilling chamber, and the feeding spout being appended to the stilling tank so as to cover the outlet of the stilling tank, the feeding spout having a spout bowl, an orifice plate defining at least one orifice, and at least one reciprocal plunger aligned with the at least one orifice of the orifice plate and that is movable with respect to the at least one orifice, wherein the stilling vessel is configured to receive unrefined molten glass through the inlet at a fluctuating flow rate and the feeding spout is configured to deliver a molten glass feed through the at least one orifice of the orifice plate at a controlled flow rate.
