Application of Short Wavelength Light Technologies in Treating Historical Paper Manuscripts against Foxing

This project was a collaborative effort between THETIS authentics Ltd (Greece), the National Hellenic Research Foundation (Greece), and the Jozef Stefan Institute (Slovenia), under the Bilateral Cooperation Programme Greece-Slovenia.

Project Objectives:

The project focused on applying short wavelength light technologies as an innovative, non-invasive method to treat historical paper manuscripts affected by foxing (reddish-brown stains caused by mold or metal impurities). The aim was to evaluate and optimize light-based treatments in order to preserve the integrity of manuscripts, safeguard cultural heritage materials, and provide new tools for conservation science.

Project Period: 2003–2005

Funded by: The European Regional Development Fund / General Secretariat for Research and Technology.
