First insight into gemstones on historical ecclesiastical artefacts in Sicily (17th‐19th centuries): A non‐invasive survey

Archaeometry, EarlyView.
Abstract A wide production of ecclesiastical artefacts is traceable in Sicily between the 17th and 19th centuries, admirable in many diocesan museums. Nevertheless, these artefacts were never studied from an archaeometric point of view: Beyond their historical value, it is time to understand whether the information concerning the decorating gemstones ...

Quality from Kent: Preliminary results from the analysis of fifth‐ to seventh‐century silver alloys

Archaeometry, EarlyView.
Abstract This paper explores early results from the chemical and lead isotope analysis of 30 silver‐alloy objects from southeast England dating between the fifth and seventh centuries CE, presenting limited aspects of the three main analyses that were conducted. First, a comparison of the results gained from surface x‐ray fluorescence (pXRF) values and

Determining the impact of elemental composition on the long‐term survival of vegetable‐tanned leather in archaeological environments

Archaeometry, EarlyView.
Abstract This research paper investigated whether elemental analysis can differentiate leather manufacturing from soil contamination and whether soil hydrology and elemental composition impact degradation of leather. Portable X‐ray fluorescence (pXRF) is a quick method for monitoring large‐scale changes and groupings of aggregate inorganic elemental ...

Elemental concentration via portable x-ray fluorescence spectrometry: Assessing the impact of water content

Ciência e Agrotecnologia
Portable X-ray fluorescence (pXRF) analysis can be considered one of the main recent advances for chemical characterization of earth materials. The water content of the samples can affect the pXRF performance.

Testing sample selection criteria and loss of biomarkers during cleaning of archaeological unglazed pottery to maximize organic residue quantities

Archaeometry, Volume 67, Issue 3, Page 536-551, June 2025.
Abstract As the number of studies in organic residue analysis (ORA) of ancient pottery—a sensitive but as of today also a destructive method—increases, archaeologists are interested in knowing which samples promise the biggest abundance of analytes in order to avoid unnecessary loss of artefacts.
