Fining of glass is usually achieved by glass batch components which lead to the formation of gas bubbles in the melt at high temperatures. It is caused by redox reactions, i.e. polyvalent compounds transferred from a higher to a lower oxidation state and gaseous oxygen is formed. These reactions can be studied in-situ in the glass melt with he aid of electrochemical methods. In this paper, thermodynamics of some fining agents are reported.
