Foxing stains on six different papers from the 16th-18th centuries and additionally fox-like stains produced by dripping different amounts (1, 3 and 5 ?l) of solutions of FeCl3, KCl and FeCl3+KCl (5·10-3 M) on modern paper and artificially ageing were analyzed for chromaticity, fluorescence under UV illumination, carbonyl content, thickness and submitted to IR spectroscopy and XRF spectrometry. As a result it is stated that the foxing phenomenon is related to a strong oxidation of the cellulose chain. Not regarding certain and possibly specific differences between different kinds of foxing stains, this strong oxidation is the only common characteristics for foxed areas.

Abstract
Foxing stains on six different papers from the 16th-18th centuries and additionally fox-like stains produced by dripping different amounts (1, 3 and 5 ?l) of solutions of FeCl3, KCl and FeCl3+KCl (5·10-3 M) on modern paper and artificially ageing were analyzed for chromaticity, fluorescence under UV illumination, carbonyl content, thickness and submitted to IR spectroscopy and XRF spectrometry. As a result it is stated that the foxing phenomenon is related to a strong oxidation of the cellulose chain. Not regarding certain and possibly specific differences between different kinds of foxing stains, this strong oxidation is the only common characteristics for foxed areas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
