Academic Materials Research Laboratory of Painted Artworks (ALMA)
Academic Materials Research Laboratory of Painted Artworks (ALMA) is a joint workplace of the Institute of Inorganic Chemistry of the CAS and the Academy of Fine Arts in Prague (AFA Prague) established by the Contract of Association in 2004. Since 2014, ALMA has been an independent scientific department within the Institute’s structure. The laboratory’s main focus lies in testing and implementation of non-invasive and non-destructive micro-analytical techniques and methodologies in the field of materials research of paintings. These methodologies, closely related to interdisciplinary research of historical painting techniques performed at AFA Prague, help in evaluation of works of art in terms of their originality, age and provenance. Consequently, experimental research of painting pigments is focused not only on the materials properties, but also on historical methods of preparation and processes of degradation in the colour layer.

Equipment
The laboratory is equipped with powder X-ray microdiffraction (micro-XRD) for phase and structural analysis of pigments in microscale. Other methods are performed in the Centre of Instrumental Techniques – particularly the electron microscopy and the infrared spectroscopy. Advanced optical microscopes and non-invasive methods, among them e.g. portable XRF and UV/VIS spectroscopy, are accessible at AFA Prague.
