Treasures from UCL

UCL has one of the foremost university Special Collections in the UK. It is a treasure trove of national and international importance, comprising over a million items dating from the 4th century AD to the present day. Treasures from UCL draws together detailed descriptions and images of 70 of the most prized individual items. Between the magnificent illuminated Latin Bible of the 13th century and the personal items of one of the 20th century’s greatest writers, George Orwell, the many highlights of this remarkable collection will delight and intrigue anyone who picks up this book

Non-destructive characterization of artworks in paper support using spectroscopic techniques

Tese de doutoramento, Física, Universidade de Lisboa, Faculdade de Ciências, 2013The work here presented aims at demonstrating the efficacy of X-ray fluorescence (XRF) with portable setups, sometimes complemented by Raman spectroscopy in providing answers for characterization, conservation and authentication issues related with artworks in paper and parchment support. The work begins with a short section regarding the state of the art on the use of portable XRF and Raman spectroscopy in the study of artworks in paper and parchment support. The suitability of the techniques has already been greatly established, however constant improvements from the technological point of view, grant different capabilities. The work is presented as a group of case studies with the intention of providing answers in three major topics: the application of μ-XRF to the study of discolorations in paper documents and drawings, the study of the pigments used in Namban paper folding screens to accomplish their characterization, dating and authentication and the establishment of methodologies for determining/evaluating the thickness of gold leaf used for gilding. In some of these case studies we were approached by conservators who had specific demands and then we pursued similar artworks to improve the corpus of study. The most remarkable aspect of these studies is that all XRF analyses were performed in situ and when there was need for complementary information micro-samples were collected for Raman analysis. This way, the main goals in Cultural Heritage studies were obtained: the artworks were not damaged nor removed from their original location.Fundação para a Ciência e a Tecnologia (FCT, PhD grant SFRH/BD/60778/2009
