The paper tackles the influence of skin surface lipids and chromatic fungal attack on the paper support and the writing of a 125-year-old document, which involves the corroboration between multianalytical techniques. Thus, the study used three specimens sampled from different areas: a standard lipid- and fungal-attack-free sample, one with old lipid film dating back to its being used by its creator (before it had entered the archives) and another with lipid film and fungal attack present on it (from after it had entered the archives). In addition to direct observation by means of magnifying instruments, our scientific research relied on the following techniques: OM, SEM-EDX, μ-FTIR and differential thermal analysis (TG, DTA and DTG). Compared to the standard sample, the data of which correspond to the natural aging process occurring between 1895 and 2020, the other two samples show evolutionary degradation effects under the influence of oxidatively fouled lipids and on small areas photochemically and thermally cornified, as well as effects due to enzymatic degradation under the influence of fungal attack. The study has a clear goal, namely to implement specific protection measures when dealing with old documents (gloves and protective mask, air conditioning niche for preservationrestoration actions).
