The Electrochemical Investigation of
the Redox State of Molten Glass


Polyvalent elements are included as additives or are present as impurities in commercial glass compositions. Many properties of the glassmelt during processing and of the resulting glass are greatly influenced by the presence and concentration of specific redox states of these polyvalent elements. Consequently, the measurement and control of the redox state of a glassmelt is of considerable importance in the manufacture of the desired glass product. One way to express the redox state of a glass is to indicate the amounts of oxidized and reduced species of the polyvalent element in the glassmelt or glass. Current controlling or monitoring the redox of the glass-making process often relies on the analysis of the quenched product, after the fact, by chemical or spectroscopic methods. The objective of these studies is to develop an in-situ "redox ratio" sensor for use in molten glass. This research is being conducted in collaboration with Dr. Henry D. Schreiber at the Virginia Military Institute.
