This extract describes the large-scale investigation designed to identify and quantify the degradation of surfaces in biocalcenes in the Temple of Concordia in Agrigento. Part of this investigation was devoted, thanks to laboratory tests, to the choice of the appropriate material to replace missing areas and to attach detached parts with adhesive substances. Not having standard procedures, several different tests have been carried out, from small to larger operations to obtain comparative analyzes. The results were then evaluated in relation to the compatibility of the materials used, their durability and compactness. This study was especially important to recognize the behavior of some materials that, although widely used, did not actually show proper behavior to the biocalcenes of the temple.
