A new PIXE facility has been constructed at the Bartol Foundation with a tightly focused proton beam (typically 50 mum across) that allows a variety of inhomogeneous archaeological artifacts to be studied in spatial detail. The practical need is discussed for micro-PIXE research in archaeology; applications could include the analysis of metal residues in smelting slag, the solder joins of classical jewelry, sound metal in corroded bronzes, and individual color bands on core-formed glass vessels. -- AATA
