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.
