Abstract: Disclosed is an apparatus for conditioning molten glass. The apparatus includes a connecting tube assembly having a conduit for conveying the molten glass, the conduit including at least two flanges and a sealing member disposed between the at least two flanges around an outer peripheral region of the flanges, thereby forming an enclosed volume between an outer wall of the conduit, the at least two flanges and the sealing member. An atmosphere within the volume may be controlled such that a predetermined partial pressure of hydrogen or a predetermined partial pressure of oxygen may be maintained within the volume. A current may be established between the at least two flanges to heat the conduit.

Abstract: A glass forming apparatus includes a glass delivery vessel, a forming body with a forming body inlet and a downcomer (48) between the glass delivery vessel and the forming body. The downcomer includes a downcomer tube (100) with an inlet end (110) for receiving molten glass from the glass delivery vessel and an outlet end (109) for discharging molten glass to the forming body inlet. An upper heating zone (110) and a lower heating zone (150) positioned downstream from the upper heating zone (110) encircle the downcomer tube and a lower controlled atmosphere enclosure (155) is positioned around and sealed to the downcomer tube (100) in the lower heating zone (150). The lower controlled atmosphere enclosure (155) includes at least one heating element (156) for heating molten glass flowing through the downcomer tube within the forming body inlet.

Abstract: A method of controlling a flowrate of molten material at a downstream location in a glass manufacturing process can include mixing the molten material at an upstream location positioned upstream from the downstream location relative to a flow direction of the molten material with a shaft including a plurality of protrusions. The method can also include measuring a torque of the shaft, measuring a level of the molten material at the upstream location, and calculating a viscosity of the molten material at the upstream location based on the measured torque and the measured level. In addition, the method can include estimating the flowrate based on the calculated viscosity, and controlling the flowrate at the downstream location based on the estimated flowrate.

Abstract: A glass manufacturing apparatus includes a vessel and a filter positioned to receive a beam of light. The filter passes a second wavelength component of the beam of light through the filter while preventing a first wavelength component from the beam of light from passing through the filter. The glass manufacturing apparatus comprises a sensor positioned to receive the second wavelength component that has passed through the filter and that has been reflected within the vessel. Additionally, methods of determining a level of molten material within a glass manufacturing apparatus and methods of manufacturing glass are provided.

Abstract: Methods are disclosed for shrinking bubbles on the free surface of a volume of molten glass contained within or flowing through a vessel, thereby minimizing re-entrainment of the bubbles into the volume of molten glass and reducing the occurrence of bubbles in finished glass products produced from the molten glass. Methods of identifying a source location for the bubbles is also described.

Abstract: An exhaust conduit for a glass melt system includes a corrosion resistant refractory conduit material, such as a conduit material including zirconia. The conduit can extend through a relatively dense refractory block material, such as a refractory block comprising alumina. The exhaust conduit can exhibit improved corrosion resistance in processing a variety of glass melt compositions.
