Fig. 8From: An assessment of multimodal imaging of subsurface text in mummy cartonnage using surrogate papyrus phantomsX-ray fluorescence images showing the presence of iron in the iron-based inks (from left, crosses in: iron gall ink; carbon ink; red iron oxide and India ink). Very faint XRF signals from iron can be seen in the phantoms with carbon based ink. Due to limited time resources, only half of the phantom containing crosses in carbon in was imagedBack to article page
