✦ Synopsis
Fragments from the archaeological site of Castel Fiorentino (Foggia, Italy) were analysed by Raman microscopy x-ray powder di †ractometry and x-ray photoelectron spectroscopy to determine the pigments used in the decoration of this medieval (13-14th century) pottery. Lapis lazuli was identiÐed as the blue pigment and such decoration was established as a characteristic of this pottery class. The brown-black pigment was identiÐed as a manganese oxide, probably
The qualitative composition of the glaze was also shown to include tin(IV) oxide MnO 2 . (cassiterite) and lead-containing oxides, along with other oxides.
