Study of the Patinas of an Outdoor Bronze Statue “Cesare Augusto” in Brindisi (Southern Italy)
The aim of this paper is the analysis of the main elements of the patinas of an outdoor bronze monument by using portable energy-dispersive X-ray fluorescence (ED-XRF) equipment designed and assembled at the University of Salento. Thanks to the versatility of the ED-XRF portable apparatus, we carried out a scan based on a limited set of measurements that was representative of the studied surface of the monument before the restoration in a relativ…
Determining Gold Thickness in Multilayer Samples by Measuring the Intensity Ratio of the Au-Lα/Fe-Kα X-Ray
Multilayer samples are used in a wide range of sectors for their functionality. In the field of cultural heritage, multilayer samples are also common, as in the case of gilded or silvered alloys in the pigment layers in paintings. The X-ray ratios Lα/Lβ, Kα/Kβ, or K/L for an element or for different elements in a multilayer sample depend on the chemical composition and thickness of the superimposed layers and on the chemical composition and thick…
In Situ Investigation of the Medieval Copper Alloy Door in Troia (Southern Italy)
This work describes experimental results concerning the chemical composition of the alloy patina and inlays from the medieval copper alloy door of the cathedral of Troia (southern Italy), dating back to 1127 CE. The analyses were conducted in situ with no sampling or sample preparation required, using a portable energy-dispersive X-ray fluorescence (ED-XRF) instrument. The compositional results show that the two door leaves were made using a bina…
Non-Destructive In Situ Investigation of the Study of a Medieval Copper Alloy Door in Canosa di Puglia (Southern Italy)
This paper reports the analyses carried out on the medieval copper alloy door (1111–1118 AD) of the mausoleum of Boemondo d’Altavilla in Canosa di Puglia (Southern Italy). The studied door is the smallest medieval bronze door extant in Italy and, unlike the other Byzantine doors, was most probably made in Canosa di Puglia and not in Constantinople. Analyses were performed to assess the chemical composition of the alloy patinas using a portable en…
ED-XRF analysis of the mediaeval copper-based door in Monte Sant'Angelo (Southern Italy)
This work regards the analysis of a copper-based door (dated 1076 AD) located at the entrance to the sanctuary of Monte Sant'Angelo (Southern Italy) by using a non-destructive technique and in situ chemical analysis. The door does not show serious corrosive phenomena and presents several types of decorative elements such as two inlays (of silver and copper colour) and three engravings (of red, black and green colour). A portable energy dispersive…
Gold leafs in 14th century Florentine painting
Gold leafs are typically present in paintings and frescoes of the Italian Renaissance in the 13th and 14th centuries. The chemical composition and thickness of gold leafs provide important information toward a better understanding of the technology of that epoch. The present paper discusses the results of non-destructive analysis carried out with a portable energy dispersive X-ray fluorescence (ED-XRF) equipment on the 14th century panel Annuncia…
Composition and Origin of Iapygian Pottery From Roca Vecchia, Italy
We have studied 35 samples of fragments of ceramic containers dated between the eleventh and the eighth centuries BC, found at the archaeological site of Roca Vecchia, some 20 km from Lecce along the Adriatic (Salentine) coastline. Analysis of the elemental composition of the finds has been performed by means of atomic emission spectroscopy in plasma and the results obtained have been treated with diverse multivariate statistical techniques. Exce…
