Abstract
A method of making glasses with manufacturing systems employing platinum or molybdenum melting, fining delivery, or forming vessel, wherein the partial pressure of hydrogen outside the vessel is controlled or manipulated, relative to the partial pressure of hydrogen inside the platinum structure, to minimize surface blistering in the glass in contact with the platinum or molybdenum.
Claims25
A method of forming an oxide glass in a manufacturing process employing a metal selected from the group consisting of platinum, molybdenum, palladium, rhodium, and alloys thereof in a melting, fining, delivery, or forming vessel of the manufacturing process, wherein an interface is present between said vessel and said glass, the method comprising:
- providing a partial pressure of hydrogen outside the vessel in an amount which is sufficient to prevent formation of oxygen blisters in the region of the glass adjacent said vessel/glass interface.
A method of forming an oxide glass in a manufacturing process employing a metal selected from the group consisting of platinum, molybdenum, palladium, rhodium, and alloys thereof in a melting, fining, delivery, or forming vessel of the manufacturing process, the method comprising:
- controlling the partial pressure of hydrogen outside the vessel relative to the partial pressure of hydrogen inside the vessel so that the partial pressure of hydrogen outside the vessel is sufficient to prevent hydrogen migration through the vessel and out of said glass.
