Technical examination of cultural heritage objects can be used to elucidate materials and techniques of an artist, workshop or cultural group, as well as in support of conservation and restoration efforts. While more permissible with some types of art and archaeological objects, sample removal for chemical analysis is used sparingly in the analysis of paintings and usually prohibited in the study of illuminated manuscripts and works on paper due to fragility of the objects and scarcity of material to sample. Instead, non-invasive methods including traditional imaging techniques like X-radiography, spectroscopies such as Raman microspectroscopy and spectroscopic imaging methods including macro X-ray Fluorescence (MA-XRF) scanning and hyperspectral imaging have been employed to study these objects. This talk will cover a number of case studies involving technical examination of both Old Master paintings and works on paper, highlight challenges in non-invasive analysis and discuss developments to improve data interpretation such as multivariate statistical analysis and machine learning.
