Abstract
Abstract Following pilot testing of the effects of alkaline-based nanoparticles on modern parchment, the treatment was extended to historical parchment. This paper describes the application and impact of calcium hydroxide and calcium carbonate nanoparticles dispersed in (i) propan-2-ol and (ii) cyclohexane on a parchment book cover dated 1570. The cover showed signs of damage resulting from contact with iron gall inks and low pH values (∼4–5). Protocols for the damage assessment of collagen in parchment as developed in the IDAP project (Improved Damage Assessment of Parchment) were used to evaluate the impact of the conservation treatments on parchment. Preliminary results have shown that the application of calcium-based nanoparticles did not produce any adverse effects on the state of preservation of collagen. In addition, positive outcomes emerged: the pH was re-adjusted to a neutral value, a strengthening and consolidation effect was observed, and the nanoparticles exhibited a protective action upon artificial ageing of the treated parchment.
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
