This research investigates the physical manifestation and chemical mechanisms and processes of biologically-induced corrosion of archaeological glass. Archaeological glass samples from Greece and Cyprus suspected to have undergone biocorrosion were analyzed to characterize the composition and surface topography and to determine the difference in the chemistry and microstructure between the glass surface and the bulk. Microscopic and analytical techniques employed include digital microscopy, polarized light microscopy (PLM), scanning electron microscopy (SEM) at variable pressure (VP) coupled with energy dispersive X-ray spectroscopy (EDS), atomic force microscopy (AFM), X-ray fluorescence (XRF) spectroscopy, and X-ray Diffraction (XRD). Modern glass samples of soda-lime-silica and lead-silica glass were synthesized to imitate archaeological glass matrices and placed in petri dishes in controlled conditions with sulfuric and oxalic acid to simulate corrosion induced by acid-byproducts produced by microorganisms. This research fills a gap in our knowledge on archaeological glass biocorrosion and evaluates the effects of microorganisms on archaeological glass.
