Technological analysis

Detailed technological analyses using a microscope as well as a range of diagnostic irradiation techniques such as ultraviolet, infrared and X-rays will accompany the conservation work. It is hoped that the results will provide a full picture of the production process, the materials used, and the painting’s history.

Image taken under UV light: A red pigment that is now almost imperceptible in the painting is fluorescing pink in the face of the central figure. The small black marks on the robe are areas of retouching.
