| Abstract: | In this work, different mosaics covered with various plasters (of thickness and composition) were evaluated in lab by means of various thermography approaches with the intention of detecting the tesserae beneath the plastered surface. Thermal images, as well as the thermal contrast curves between plain plastered surfaces and plastered mosaics were recorded. Results from the assessment are presented and discussed, indicating that images seeing through the mortar–plaster on plastered mosaic surfaces can be obtained using numerous thermography approaches. |
