Paper Abstract

Infrared thermography is a non-destructive testing technique that affects many areas. This technique of analysis is, for example, very interesting in the field of restoration and conservation of heritage works. The possibilities of active thermography can help in the early detection of defects in works of art and their characterization. In this work we will demonstrate that it is possible to detect old restorations in frescoes and murals by flash method. This new possibility offered by thermography will make it possible, for example, to verify the compatibility of a restoration with the original work, which can prevent the appearance of a defect and may allow the conservator to follow up on restoration. First we will show the feasibility of this approach on a laboratory specimen containing different types of clogging materials and then present results of analysis carried out in situ at one restoration sites that reveal the possibility of locating these restorations but also to characterize the pictorial technique used in this one.
