Abstract

Disclosed herein are methods for modifying a glass composition, the methods including delivering a molten glass to a ceramic forming body including at least one cavity containing a first electrode and a mobile ion source or a mobile ion sink, contacting the molten glass with a second electrode, and applying an electrical field between the first and second electrodes to create an electrical potential difference sufficient to drive at least one mobile ion into or out of the molten glass through an intergranular glass phase of the ceramic forming body. Ceramic forming bodies including a crystalline phase, an intergranular glass phase, and a cavity containing a first electrode and a mobile ion source or a mobile ion sink are also disclosed. Glass sheets manufactured using the disclosed methods and forming bodies are further disclosed.
