Part I: A Laboratory Samples Study [Elektronische Daten] [Celine Remazeilles, Veronique Rouchon-Quillet, Jacky Bernard] Influence de la gomme arabique sur la corrosion de l'encre gallique 1ère Partie: Modification de la couleur et des propriétés mécaniques des échantillons de laboratoire In the Western world, Gum Arabic has been extensively used as a binder in iron gall ink preparation. Its impact on iron gall ink corrosion of paper was investigated on laboratory samples. These samples comprised cotton linters cellulose paper (no charge, no fillers, no size) impregnated with different solutions combining the three main ingredients of iron gall ink, these being gallic acid, iron sulphate and Gum Arabic. The paper degradation caused artificial ageing was evaluated by colour measurements, mechanical test and FTIR spectrometry. It was observed that, in the presence of Gum Arabic, cellulose degradation induced by the presence of iron was delayed. This observation can be interpreted in several ways: first, the gum may physically protect the paper, by coating the paper fibres, and thus limiting the diffusion of free iron II. Secondly, the gum could be interacting chemically with iron II and is degraded by the iron(II) rather quickly. Also, the free iron II ions, which are involved in Gum Arabic corrosion, may not then be involved in the catalysis of the cellulose oxidation. © 2004 K. G.
