Abstract: Iron-gall inks were the most commonly used writing and very popular drawing media since antiquity. Nowadays, the degradation of this aged paper can be observed. One possible reason for degradation of iron-gall inks is acid hydrolysis of glycosidic bonds. The second one might be iron-catalysed oxidation of cellulose. The aim of this work is to investigate the influence of the iron-gall ink on aged paper. Same behaviour is expected in case of either the breaking length, the thermal stability, the adverse effect on the permanence, or the decrease in temperature of maximal rate of decomposition. These assumptions will be proven or rejected.
Keywords: iron-gall ink, paper degradation, mechanical properties, ageing
