“…In this paper the authors propose an innovative technique to evaluate the integrity state of archaeological discoveries based on the use of thermography. Thermography is today widely used for environmental monitoring applications, [8], [9]. In the paper, it is described the potentiality of passive thermography in monitoring archaeological discoveries and historic sites, [10], [11].…”

In this paper the authors propose an innovative technique to evaluate the integrity state of archaeological discoveries by using thermography. The proposed approach is based on the concept of emissivity. The case study is a marble bust of a woman that dates back to ancient Rome. The emissivity of the bust material has been evaluated by using a standardized procedure. To assess the integrity state of the sculpture, the environment temperature has been kept under control to allow the bust to reach thermal equilibrium. By evaluating pixel by pixel, the temperature deviation around the known equilibrium value, it has been possible to map the emissivity changes in the sculpture due to different conservation or decay states: alveolisation process, erosion, damages, deposition of iron oxide, etc. The proposed approach has allowed us to correlate the changes of emissivity with the integrity state of the sculpture. Preliminary studies on the bust provide interesting information about the deterioration from the original condition.

“…The authors propose a thermography-based technique to evaluate the conservation state of the archaeological discovery so to schedule the next restoration activity, [8], [9]. Thermography is a diagnostic technique used in several application fields such as the environmental one, [10], [11], biomedical one [12] and industrial one. The authors in previous works have proposed the use of thermography for diagnosing the conservation state and for detecting surface cracks and defects of archaeological discoveries.…”

In this paper the authors propose the use of passive and active thermography to support the restoration of archaeological discoveries. Archaeological restoration is a time-consuming activity entailing high costs. Therefore, the possibility to schedule restoration when it becomes necessary is an important goal. In addition, to guide the restorer on the parts of the archaeological heritage which require urgent maintenance can be a significant support. The proposed technique allows to detect the damaged parts due to material alterations like alveolisation processes, erosions, deposition of iron oxide, defects, fissures, and material irregularities. By evaluating pixel by pixel, the temperature deviation around the known equilibrium value, it is possible to map the material alterations or the parts affected by decay states. Such material alterations are often invisible to the naked eye especially at their onset. This technique allows to highlight the material alterations on the artefact surface by characterizing the emissivity changes. Experimental results on an ancient medallion and on fragments of a marble sarcophagus are reported to prove the relevance of the proposed methodology.
