The Influence of Iron Gall Ink on Paper Ageing.

The article examines the behavior of iron elements in prepared iron-gall inks and its influence on paper ageing. It provides a review of literature about the essential qualities of iron gall inks and its properties. Furthermore, the authors present the experimental design of the study including the materials and equipment used, the preparation of samples, and the methodology. Based on the results, the catalytic activity of iron ions in cellulose degradation mechanisms was verified and the relationship between the acid-catalyzed hydrolysis and meta-catalyzed oxidation of cellulose was demonstrated.
