Abstract

The composition of the glaze of a selection of maiolica wares acquired by the Museo Nazionale del Bargello (Florence, Italy) between the 19th and the 20th century was investigated in this study. The authenticity of the objects was questioned on the basis of their style, condition and acquisition history. This project aimed both at providing analytical data useful for the authentication and developing a non-invasive, in-situ methodology to characterise the artifacts. Maiolica samples of known provenance - both ancient and dated to the 19th-20th century - were used as a reference and were analysed by optical microscopy, SEM-EDS, PIXE-PIGE and portable XRF mapping (p-XRF). This was particularly important for the 19th-20th-century objects, which have been rarely studied in the past. Afterwards, the biscuit of the possible forgeries was authenticated by thermoluminescence (TL), while the composition of their surfaces was analysed at the Bargello by means of p-XRF.
