Red Iron Oxide. FeO (Ferrous Oxide) -In clays and glazes, firing in reducing conditions, or with clays containing significant organic matter, the Fe2O3 converts to FeO as early as 900C. FeO is a very powerful flux. Once iron has been reduced and becomes active in glass forming, it is difficult to reoxidize it again.
