Experimental research in ALMA is carried out in close connection with the analysis of actual paintings and obtained micro-samples. This leads to creation of a two-way feedback system. Thanks to the link to analyses, restoration and art-historical research, questions for a broader experimental research are being purposefully formulated – thus guaranteeing that the research always has practical merits. On the other hand, the final results of fundamental experimental research are immediately implemented into the interpretations and conclusions of material surveys of specific artworks.

Experimental research in ALMA is led in three main directions. The first is the collection, preparation and analysis of various reference samples, including the replication of complicated pigment production and verification of historical procedures. The second one covers technological and painting experiments, including the preparation of composed model samples and technological copies of specific paintings. The third and very broad direction includes long-term experiments focused on interactions of materials in the colour layer, which may result in undesirable degradations, and monitoring the influence of external factors (humidity, temperature, lighting, etc.).
