Chemical analysis of refractory material glass and glazes. Determination of Fe2+ and Fe3+ by the spectral photometric method with 1,10-phenanthroline1 Scope This International Standard specifies a spectral photometric method with 1,10 phenanthroline for the quantitative determination of Fe2+ and Fe3+ in oxidic raw and basic materials for ceramics, glass and glazes, e. g. feldspar, kaolinites, clay, limestone, quartz refractory materials. This International Standard could be extended to other aluminosilicate materials, providing that uncertainty data is produced to support it. However, there might
