| Abstract: | CONCLUSION. This preliminary work puts to evidence that the presence of gallic acid in the ink increases significantly the concentration of iron(II), thus enhancing the iron gall ink corrosion. Mossbauer spectrometry proves also to be a powerful technique for the understanding of iron gall ink corrosion mechanisms. Despite the low concentration of iron in the paper, some measurement could be undertaken in an efficient way. One can expect, with this technique to draw much more information on the environment of iron and to identify the iron gall complex and the different iron oxides present in the ink. However, the first results presented here should be considered with great caution. More references are required to confirm the identification of the iron sites, and some further measurements will be undertaken at low temperature to improve the quality of the data. |
