“…EDXRF and Micro-PIXE are non invasive, multielemental and relatively fast techniques, which have been frequently used in the chemical characterization of archaeological metallic materials, namely gold artefacts and solder alloys (Demortier 1991;Demortier et al 1999;Alves et al 2002;Bugoi et al 2003;Soares et al 2004). Nevertheless, sometimes it is not possible to solve research problems only with a non invasive approach.…”

Early Iron Age gold buttons from Castro dos Ratinhos, Fortios and Outeiro da Cabeça were analysed by conventional EDXRF, Micro-PIXE, SEM-EDS and Optical Microscopy. EDXRF results point out to a rather homogeneous alloy composition throughout all the analysed buttons. PIXE microanalyses show that all the button components (disk, tab and peripheral grooved decorated rod) have the same alloy composition. PIXE and SEM-EDS microanalyses, supplemented with optical microscopy characterization, show the absence of chemical composition differences between distinct components and joining zones, suggesting that no solder had been applied, i.e. that a partial melting/solid state diffusion process had been used for the welding of button components. Finally, the noticeable similar compositions together with the use of the same welding process and the very similar artefact typologies suggest that those small gold treasures could be interpreted as the result of the work of a single metallurgical workshop, probably located somewhere in the South-Western Iberian Peninsula.

“…he ancient gold alloys contained many trace elements, such as lead, tin, platinum, palladium, zinc, bismuth, and antimony (Bugoi et al, 2003;Craddock, 2009;Demortier et al, 1999;Guerra, 2008;Guerra and Calligaro, 2003;Ontalba Salamanca et al, 1998;Ott and Schindler, 2001). he absence of a signiicant set of trace elements in this alloy is abnormal.…”

“…To these purposes, scientists can contribute useful information regarding the composition of the alloy, the analysis of deposits, and the weathering degree. Most of the studies on gold artefacts aim to deine the origins, trade and provenance of the ores based on the trace elements composition (Guerra and Calligaro, 2003;Bugoi et al, 2003;Demortier et al, 1999;Ontalba Salamanca et al, 1998).…”

“…Gold leaf is very suitable for the gilding of silver or copper blanks as it is easy to achieve strong adhesion to the metal underneath [53]. In Amerindian civilizations, a copper-gold alloy with a high copper content was used to cast the bulk and then, a heating process was carried out in order to achieve a depletion gilding procedure, giving to the final product a suitable golden aspect [68]. Nowadays, there are a number of samples that have a noble metal coating, such as costume jewelry items and others of technological interest, in which the accurate measure of the coating thickness can be very useful [69].…”

This paper reviews the use of X-ray fluorescence spectrometry (XRFS) for non-destructive studies of valuable metallic objects in the fields of jewelry, archaeology and art, as well as its application in the analysis of coatings and solutions, due to the interest of these issues in jewelry manufacture. The general features of the technique as well as the most outstanding results obtained in the commented fields are described, taking into account the most important sources of error, mainly in the case of samples that have suffered corrosion processes.
