Abstract
A method of dealkalizing a glass body that contains at least one alkali metal ion as either an impurity or an intentionally added constituent. The method involves intimately contacting the glass body with a hydrogen-ion-producing anode and an oxide receptor for the alkali metal ion as a cathode and exposing the glass body and electrode assembly to hydrogen while the assembly is at an elevated temperature.
