Resumo

This paper describes the effect of various iron-gall inks on acid and alkaline papers and their relation to biodeterioration. Different types of papers were used in the present study, where several tests were performed: spot-tests for lignin and starch detection, chemical digestion to quantify total iron content, desorption studies to remove iron from the papers, followed by accelerated artificial aging, scanning electron microscopic studies and biodeterioration tests. Results indicated that lignin was only detected on acid papers, while starch was detected both on acid and alkaline papers. Treatment with calcium phytate proved to be an efficient process to remove excess iron from the inks. Scanning electron microscopic images showed distinct surface spreading of inks on the papers, depending on the iron content. Finally, in the absence of any other carbon source, papers strips containing iron-gall inks proved to be amenable to biodeterioration, indicating that chemical and biochemical deterioration simultaneously occur.
