More analysis and diagnosis using X-ray radiography, electromagnetic radar, high spec digital microscope was carried out by the wall painting team and scientists of analysis and diagnosis team. In order to assess the internal structures by application of modern science and technology, X-ray radiography and digital microscopes were procured by the project. Non-destructive observation of pigment was made possible using digital microscope. Result of X-ray showed that there are hidden gaps between the mud bricks which constitute the sub-structure of the wall paintings under the painted layer. Another non-destructive method, electromagnetic radar was used in the EM to investigate weak spots such as cavities in the wall that are not visible from the outside.
