Abstract
Fragments from the archaeological site of Castel Fiorentino (Foggia, Italy) were analysed by Raman microscopy x-ray powder diffractometry and x-ray photoelectron spectroscopy to determine the pigments used in the decoration of this medieval (13-14th century) pottery. Lapis lazuli was identified as the blue pigment and such decoration was established as a characteristic of this pottery class. The brown-black pigment was identified as a manganese oxide, probably MnO2. The qualitative composition of the glaze was also shown to include tin(IV) oxide (cassiterite) and lead-containing oxides, along with other oxides. © 1997 by John Wiley & Sons, Ltd.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
