61This sample was collected from the green-colored leaf from the flower garland after removal of the overpaint and degraded surface coating. The red-brown ground can be seen followed by a thin layer of green paint rich in yellow/green earth and lead white with a trace of vermillion from the edge of the red flower (visible light/ultraviolet light/100x magnification). Ultraviolet illumination helped to reveal the presence of a double red-brown ground as well as a curious auto-fluorescent glaze layer between the paint and ground layers. This layer may correspond to a pigmented glaze/varnish layer that was applied to this area before the artist(s) began the painting process.

62This sample was collected from the green-colored cushion on King Saul's throne before removal of the degraded surface coating. The red-brown ground can be seen followed by a two thin layers of paint (visible light/ultraviolet light/100x magnification). Ultraviolet illumination helped to reveal the presence of a double red-brown ground, green earth particles in the paint layers, and the thick nature of the degraded surface coating in this particular section of the painting.
