Abstract
Underwater ceramic sherds, found in the harbor of Crotone (Calabria,Italy), were analyzed with different analytical methods. The potteryfragments, mostly amphorae, are characterized by a great layer ofencrustation on the surface. Archaeological information are very poor, noassumption about provenance and technology, these ceramics are onlydoubtfully dated to Medieval times.The petrographic (Optical Microscopy) and chemical analyses (X-RayFluorescence) on the ceramic of Crotone evidenced a strong compositionalheterogeneity. Comparison with literature data supported two differentproduction areas: Western (Southern Italy) and Aegean area.UV Fluorescence on biotic crusts, allows to evaluate the relationshipbetween the biotic colonization and the ceramic paste and to trace thealteration pervasiveness due to the encrusting organisms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
