    摘要： An apparatus for melting and refining a silica-based glass composition includes a vertical first reaction chamber having an input adjacent to a lower end for receiving glass-forming components. The glass-forming components are heated to elevated temperature during upward flow through the vertical first reaction chamber to form a glass precursor melt adjacent to an upper end of the vertical first reaction chamber. A vertical second reaction chamber has an input adjacent to an upper end and an output adjacent to a lower end for delivering glass melt. A cross passage connects the upper end of the vertical first reaction chamber to the upper end of the vertical second reaction chamber such that the precursor melt flows from the vertical first reaction chamber through the cross passage and then through the vertical second reaction chamber to homogenize the precursor melt. Vacuum preferably is applied to the cross passage both to assist upward flow through the vertical first reaction chamber, and to assist refining of the precursor melt during such upward flow and during flow through the cross passage.

    摘要： A method for producing a glass includes forming a horizontal stream of molten glass and mixing the stream. The mixing is created by rotatingly driving n shafts, n being a whole number equal to or greater than two, each having an axis, two adjacent shafts being separated by a distance with their axes parallel and with each of the two adjacent shafts connected to a rod located at least in part in the stream and each of the rods having an axis parallel to the axis of the shaft to which it is connected. For the two adjacent axes, the distance between the axis of one rod and the axis of the shaft to which it is connected is in excess of or equal to 9/20 of the distance between the axes of the two shafts. The two adjacent shafts are rotatingly driven in opposite directions with respect to one another.

    摘要： A soda-lime-silica glass for solar collector cover plates and solar mirrors has less than 0.010 weight percent total iron as Fe2O3, a redox ratio of less than 0.350, less than 0.0025 weight percent CeO2, and spectral properties that include a visible transmission, and a total solar infrared transmittance, of greater than 90% at a thickness of 5.5 millimeters, and reduced solarization. In one non-limiting embodiment of invention, the glass is made by heating a pool of molten soda-lime-silica with a mixture of combustion air and fuel gas having an air firing ratio of greater than 11, or an oxygen firing ratio of greater than 2.31. In another non-limiting embodiment of the invention, streams of oxygen bubbles are moved through a pool of molten glass. In both embodiments, the oxygen oxidizes ferrous iron to ferric iron to reduce the redox ratio.

    摘要： A glass bottle forming system is described in which a main glass melter is connected to a forehearth with a fairly conventional feeder provided at the delivery end of the forehearth. The feeder opening in the bottom of the forehearth is closed by a first orifice member through which a molten core glass will flow. Beneath the first orifice there is positioned a second orifice member that has an orifice that is slightly larger than the orifice in the first orifice member. A small melter contains a glass of essentially the same composition as that in the main melter, but with a coefficient of expansion slightly less than that of the core glass. This lower expansion glass is fed to the second orifice member so that it can flow out of the orifice with the core glass in surrounding relationship with respect thereto. The skin glass melter is connected to the second orifice member by a gravity feed system in which the connection is thermally controlled so that the viscosity of the two glasses are maintained essentially the same. Two embodiments of the skin melter and the second orifice are disclosed. In one embodiment the second orifice is vertically adjustable so as to vary the volume of skin glass flow relative to the core glass flow. The second embodiment has the second orifice supporting an annular bushing that is vertically adjustable and it cooperates with the bottom of the upper orifice member to regulate the flow of glass into surrounding relationship to the core glass coming through the first orifice member.
