abstract = {In recent decades, μ-Raman spectroscopy has become a powerful technique for studying ceramics, with the
advantage of performing fast, reproducible and reliable analyses that provide effective information on ceramic
technology. In the present paper, the potential of μ-Raman spectroscopy was evaluated by comparing the results
of spectroscopic analyses with a wide range of conventional compositional and mineralogical analyses. Particular
fragments of pottery from the archaeological site of Pollena Trocchia (Campania, Italy), characterized by a
variegated color zonation, a symptom of uncontrolled firing conditions, were subjected to in-depth analytical
investigation. Data from the μ-Raman measurements were in very good agreement with the analytical set of
conventional analyses and permitted to better constrain the firing temperatures, evaluate changes in the
oxidative steps, and assert the provenance of volcanic raw materials. The results illuminated that pottery was
crafted by mixing a low-CaO base clay with volcanic temper from the environs of Vesuvius and fired in a not
well-controlled firing atmosphere, which determined the development of Fe(III) oxides at rims of sherds and Fe
(II)-bearing phases at cores. Moreover, even in the absence of newly-formed minerals, firing temperatures were
estimated between 900 and 950 ◦C, as suggested by the mineralogical and spectroscopic evidence of the prograde
10 Å dehydroxylated phyllosilicates.},
