An awesome achievement. I don't know if it's possible but I wonder if they could do energy-resolved CT and try to look for a differential absorption edge in that ink. I have no idea what material it is actually made of, but if the IR photo is different, then there's a nonzero chance they could generate quite significant contrast by hitting one of the K-shell edges of a characteristic ion (iron?) present in the ink but not in the papyrus itself. I've been to Diamond in the past but don't know enough about this experiment. Some of them are definitely energy resolved. Utterly brilliant. I'm so glad it appears to be a bit of scholarly writing too, which is what I know most classicists secretly love!
