“…The concentrations of phosphorus (P) are of interest in relation to human activity. However, P was rarely detected in our samples, probably due to instrumental limitations in measuring light elements in sediments by pXRF (Hunt and Speakman 2015). Most of the detected P signals do not correlate with the apparent human activity phases, such as the Iron Age field erosion (at the uppermost ca.…”

“…PXRF analysis of unprepared sediment samples can generate semi-quantitative concentration values of high-Z elements applicable for the chemical discrimination of different sediment layers. However, values in the low/mid-Z range should be treated with caution given the analytical limitations of this instrumentation, mainly the lack of vacuum and suitable calibration (Davis et al 2012;Hunt and Speakman 2015;Holmqvist 2017). In particular, accuracy issues affect the elements Na, P, V, Cr and Ni, which cannot be accurately quantified (Hunt and Speakman 2015).…”

However, of these elements, P was included our analysis, as it was detected at several sediment depths.…”

“…The chemical characterization of samples was performed by portable X-Ray Fluorescence (pXRF), which in recent years has become more commonly used for the study of archaeological ceramics (Forster, Grave, Vickery & Kealhofer, 2011;Hunt & Speakman, 2015;Tykot, 2016). A major advantage of pXRF is that instruments can be transported to study objects in situ, thereby permitting multi-element analyses of archaeological materials in non-traditional laboratory environments.…”

Abstract:In the study of archaeological ceramics, it is important to have compositional data to identify their origin and source. The fabric also provides useful information on the production technology, especially with regard to the firing steps. The work presented here is connected to this field and focuses on the main parameters related to the terracotta artefacts preparation. Thus, one can consider the effects in terracotta characteristics of different raw materials and firing parameters, in particular for pottery of Caltagirone, which is one of most important centres of pottery production in Italy, active since the Neolithic. To this end, terracotta samples have been reproduced in a laboratory setting according to the ancient procedure of Caltagirone manufacture, starting from clay and degreaser extraction in local historical sites. The analysis was conducted using a portable X-Ray Fluorescence (pXRF) spectrometer for elemental characterization of sand degreaser and of clays during each step of the realization process and in different firing conditions. SEM-ED techniques were also employed to verify the method and results for some of the samples after firing process. Framing the technological context of manufacture production, known in the specific case, it is also possible to identify potential outcomes and limits in the study of potsherds using pXRF technology, in applying the methodology to historic artefacts.
