The combined effect of alkali and alkaline-earth ions on the redox, distribution, coordination and environment of Fe ions in alkali-alkaline-earth-silica glass has been studied using a multi-technique approach. Wet chemical analysis and Mossbauer, electron spin resonance (ESR), optical absorption and photoluminescence spectroscopies were utilised. Behaviour generally falls into two categories, which have been termed collective and selective.
