    Abstract: Apparatus and methods are disclosed for forming a glass article in which molten glass is heated in a refractory vessel defining a space interior to the refractory vessel. A precious metal component is exposed to the interior space. The apparatus includes first and second electrodes exposed to the interior space. A first electrical power source configured to supply a first electrical current is connected between the first and second electrodes. A second electrical power source is connected between the precious metal component and at least one of the first electrode or a first auxiliary electrode and configured to provide a second electrical current out-of-phase with the first electrical current. A third electrical power source is connected between the precious metal component and at least one of the second electrode or a second auxiliary electrode and configured to provide a third electrical current out-of-phase with the first

    Abstract: A glass manufacturing apparatus including a delivery vessel including a body portion with a cylindrical inner surface extending along a central axis of the body portion. In one embodiment, an upper end of the body portion is substantially equal to or lower than an uppermost portion of a travel path in a downstream end of a conduit connected to the delivery vessel. In another embodiment, a central axis of a delivery pipe is offset a distance from the central axis of the body portion of the delivery vessel. In still another embodiment, the delivery vessel includes a conical top including a taper angle from greater than 0° to about 20°. In further embodiments, methods include manufacturing glass with one or any combination of the above-referenced embodiments of glass manufacturing apparatus.
