| Doing Chemistry at the Art/Archaeology Interface
The archaeological chemical rewards of spending a sabbatical year in
Israel and Italy will be discussed along with modern methods used to
examine both ancient and modern artifacts. The archaeological work in
Israel involved analysis of ancient pigments and dyes found on
excavated materials from caves in the Judean desert and the ancient
fortress of Masada. Textiles from the "Cave of the Warrior" were
examined from their pigment content. The work in Italy involved
examination of medieval artists' manuals for recipes for blue pigments,
which were then carried out and characterized, with some surprising
results. Additional applications of the methods of archaeological
chemistry to such famous artifacts as the forgeries of Han van Meegeran
and the Shroud of Turin will be discussed, including some evidence that
the radiocarbon date of the shroud may not be valid because of fire
damage it experienced by the Shroud in 1532. Pros and cons will be
discussed.
