Raman study of the brownish-yellow pigment from a Roman Basilica (Dobrogea, Romania – 4th–6th century A.D.)
Journal Title: Analele stiintifice ale Universitatii "Alexandru Ioan Cuza" din Iasi - seria Geologie - Year 2011, Vol 57, Issue 2
Abstract
11 fragments of wall painting from the Beroe fortress, Romania (4th –6th century) were analysed through Raman spectroscopy. The yellow-brown pigment on the fragments is jarosite and/or Na-jarosite. Other than at 445 cm-1, the Raman lines of all the spectra are identical. This Raman line is slightly shifted in different spectra, and this fact proves the presence of both jarosite and Na-jarosite.
