Abstract
Abstract Ink corrosion on parchment is a phenomenon that, unlike its counterpart on paper, has so far been little researched. The same applies to the options for conservation treatment. In order to provide a guide for conservation practice as well as further research, five water-based treatment methods were examined: calcium phytate with pH 5.3 or 3.0, a 0.5% (w/w) solution type B gelatine, a 1% (w/w) solution of phytic acid at pH 2.2 and calcium phytate in combination with gelatine. These were tested on 70 specimens cut from on piece of buffed vellum and 36 specimens from an early modern deed on parchment that showed signs of ink degradation. After treatment and accelerated ageing, the samples were examined with colorimetry and ATR-FTIR spectroscopy and tested with bathophenanthroline for free iron ions. None of the tested treatment methods achieved a fully reliable inhibition of ink corrosion, but apart from a moisture-catalysed acceleration of degradation reactions, no adverse effects were observed either. Results from ATR-FTIR suggest that oxidation plays a more important role in damage related to ink corrosion of parchment than hydrolysis.
期刊介绍:
Restaurator is the only international periodical specializing exclusively in the conservation of library and archive materials. Articles examine the many important aspects of this subject area, such as technology, practical experience and organization. They also focus on scientific basics: Many articles deal with the development of new preservation techniques and the improvement and better understanding of established methods. The articles are written in English with summaries in English, French and German. By reading Restaurator regularly, librarians, archivists and restorers can keep up to date with the latest research and developments. The editorial committee is made up of experts from well-known institutions and organizations from all over the world
