This paper describes a potentiometric method for the quantitative determination of two cerium oxide forms--cerium dioxide and dicerium trioxide--in glasses where the oxides form a major constituent. The method uses hydroquinone as a reducing agent. Cerium valences are also determined. The sensitivity of the method is tested by analyzing known synthetic mixtures simulating the composition of the glasses. The method has been used to determine the total concentration of cerium and to monitor the redox regime in glass melting furnaces during the melting of cerium-containing glasses.
