Evidence
"identifiable as that of verdigris, Cu2(O2CCH3)4·Cu(OH)2, or one of its chemically very similar variants (Fig. 1c)."
Remarks
Verdigris was found in the form of friable fragments trapped in the gutters between folios (f. 93v and f. 94v). It is notoriously difficult to identify in situ with red laser excitation via a microprobe system due to its poor Raman scattering properties (p. 9).
