Hello
To determine the weight percentage of iron oxides in glass, Mössbauer spectroscopy is one of the best options, but unfortunately, this analysis is not performed in Iran, and X-ray spectroscopy is not able to perform such analysis due to the amorphous structure of glass and the low percentage of iron oxides. Please let me know if you have experience or information about an analysis to determine iron oxide weight percentages and glass redox determination.
Thank you for your time in line.
Davood Ghanei Normally the glass would be powdered and either the Fe solubilized with HF as in any geological analysis or XRF used. The Fe content would then be determined with AAS or ICP (or in the old days colorimetric methods) for solutions. XRF may be more convenient. A Google Scholar search will probably be effective. I picked up the attached within 5 seconds of a search on "Determination of iron content in glass".
Davood Ghanei For XRF take a look at: https://www.youtube.com/watch?v=NphKVW8og18
You may also want to look at ASTM E2926-17 Standard Test Method for Forensic Comparison of Glass Using Micro X-ray Fluorescence (µ-XRF).
EDS, XRF, RBS, SIMS ... can be used for Fe analysis in soda lime glass.
