Two Byzantine Albanian icons: a non-destructive archaeometric study

The present work is part of a project aimed at studying the pigments and painting techniques used by Albanian iconographers to produce Byzantine and post-Byzantine icons dating from the fourteenth to the nineteenth centuries; the state of conservation of these icons was also explored. Inorganic pigments are identified by means of X-ray fluorescence, reflectance spectrophotometry and UV fluorescence analysis. These analysis techniques were performed to discriminate between pigments on the basis of their typical features. Moreover, the study of the optical properties of paintings is of fundamental importance for correct restoration. This work enabled us to recognise the palette used in two artworks by anonymous painters of the fourteenth and fifteenth centuries. Only three small samples were taken from the edge and the back of the wooden tables in order to achieve information on preparatory layers. Twelve to fourteen non-destructive measurements were made to characterise the palette used by the two anonymous painters.
