Poster Information
Abstract: Libraries, ethnological collections and natural history museums often host a wealth of exhibits of organic materials composedofcollagen (e.g. parchment) and keratin (e.g. wool textile,feather hide) proteinaceous materials. As these exhibits compose documents of historical, ethnological and physical significance, their preservation holds enormous importance for defininglocal heritage values, and even those of entire nations. Organic components in parchment, textile and feather, often unprocessed, are very susceptible to environmental conditions (oxygen,heat, light) and often carry deposited particulate material such as dust, soot, dirt and other added substances such as oils,colorants, etc. Therefore, their removal should be conducted incontrolled and targeted ways in compliance with universally accepted codes of conservation-restoration ethics (ICOM 1985).To this end, an initiative aiming at laser cleaning of parchment, wool textile surfaces as well as feather has been undertaken. Laser technology has been applied on specimens of thesematerialsand a number of laser cleaning systems and methodologies have been examined in order to determine the optimum parameters. Theeffectiveness of the laser cleaning has beentested with the use of physicochemical analysis techniques on the treated surfaces: Attenuated Total Reflection – Fourier Transform Infrared (ATR-FTIR) spectroscopy and in some cases,with High Performance Liquid Chromatography (HPLC).Summary: Parchment is composed basically of collagen (a fibrous protein) as main material, along with other proteins, fats and added components such as carbonates (as result of liming). In this study the removal of Ferric stains from parchment has been considered; the goat parchment specimens (approx. 8x3 cm) were prepared and stained following two different methodologies, while laser cleaning was tested using IR (1064nm) and VIS (532nm) wavelengths.References: [1] Fotakis C., D.
