The redox state of iron in glasses depends on temperature, oxygen fugacity and chemical composition and influences the properties of silicate glasses l.The thermodynamics of redox reactions involving iron have been experimentally tested and modelled 2,3 showing amongst other things that high temperatures favour the eduction and that higher oxygen fugacities favour the oxidation of iron.
