Conservators continued diagnostic analysis at GEM-CC for follow artifacts, using hand held XRF device, which is an elemental analysis instrument that uses X-ray fluorescence technology to identify the elements of the scanned surface, which is the mural paintings in this case.

First, the team preformed non-destructive XRF analysis directly on different colored area according to information on color differences coming from multi-spectral imaging technique, to suggest the pigments that is presented on the surface of the paintings.

The results of these analysis provided useful information about the painted preparation layers, which not only help deepen the understanding of the conservation condition of the artifacts but also is expected to prove helpful in conducting further research to gain new archaeological knowledge.
