A known method for homogenizing glass includes the following steps: providing a cylindrical blank composed of the glass, having a cylindrical outer surface which extends between a first end face and a second end face, forming a shear zone in the blank by softening a longitudinal section of the blank and subjecting it to a thermal-mechanical intermixing treatment, and moving the shear zone along the longitudinal axis of the blank. To reduce the risk of cracks and fractures during homogenizing, it is proposed that a thermal radiation dissipator is used that at least partially surrounds the shear zone, the lateral dimension of which in the direction of the longitudinal axis of the blank is greater than the shear zone and smaller than the length of the blank, the thermal radiation dissipator being moved synchronously with the shear zone along the longitudinal axis of the blank.

Apparatuses for interfacing with an electrode provided with a melting furnace including a vessel and an electrode. In some embodiments, a support assembly (50) supports the electrode outside of the vessel, and includes a cart (102) or similar apparatus that permits or facilitates selective vertical movement of the electrode and selective transverse movement of the electrode. In some embodiments, a push assembly (52) interfaces with a rear face of the electrode outside of the vessel, and is operable to apply a pushing force onto the rear face. The push assembly can include one or more tracks (e.g., threaded screw) that supports a body between opposing arms of a fixed frame. The body can translate along the tracks to apply a pushing force onto the electrode.

A method for reconditioning a glass manufacturing system includes establishing a reducing atmosphere in a glass melting vessel and draining a glass melt composition from the melting vessel while the reducing atmosphere is in the vessel. The pressure of the reducing atmosphere is greater than the pressure of the atmosphere surrounding the melting vessel and the reducing atmosphere is established by operating at least one combustion burner in the melting vessel in a fuel-rich condition.
