Greg Hills@Chapps You're already more aware of the topic than I am, but I thought this Guardian article would be up your alley if you haven't already seen it.
They even linked to their source, bless 'em.
Chapps@winterknell Yes! I've been looking at the data over the last week and posted a bit about it on the 'other site'. I've been praying that the Parthenon marbles would get tested for pigments, and the result is entirely expected (even with all the cleaning and weathering). Some surprises about textures, and I have to look into that more.
