Analysis of iron gall inks using XRF and SEM-EDX

XRF analysis of historical inks show iron as the most important metal with most common concentrations between 0,25 - 0,27mmol/g. In the majority (85%) of the inks, copper content was below the detection limit of the method 0,008mmol/g. SEM-analysis showed that Fe, Na, K and Ca were present in all inks at least as traces. S, Al, Si, Mg and Cl were present in nearly all manuscripts.

In order to detect the source for the high potassium contents of the inks, gall-nuts and gum arabic of several provenances were analysed as well. Potassium was indeed always present, sometimes also Ca, Al and Mg. The results are useful for the development of novel conservation solutions.
