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

Ceramic composition at Chalcolithic Shiqmim, northern Negev desert, Israel: investigating technology and provenance using thin section petrography, instrumental geochemistry and calcareous nannofossils [PDF]
, 2018 Technological innovations in ceramic production and other crafts are hallmarks of the Chalcolithic period (4500–3600 BCE) in the southern Levant, but details of manufacturing traditions have not been fully investigated using the range of analytical ...

The prehistoric individual, connoisseurship and archaeological science: The Muisca goldwork of Colombia [PDF]
, 2015 Unlike art historians, archaeologists rarely make systematic attempts at attributing artefacts to individual artisans - they stop at the broader category of 'provenance regions' or 'technical styles'.

Archaeometry, EarlyView.Abstract This paper presents the first direct evidence of the slags produced during the cementation alloying process of Cu with speiss inside ceramic crucibles, thus representing Cu alloying with As in Middle Kingdom Egypt. The settlement deposits from the Middle Bronze Age were excavated on Elephantine Island, within modern Aswan.

The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire
Archaeometry, EarlyView.ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.
