“…A striking difference between natron and plantash glass (here combined referred to as soda‐lime‐silica glass; Sayre & Smith, 1961; see discussion in Freestone, 2023) relative to wood ash glass is the significantly lower sodium content in wood ash glass (<3 wt% versus >10 wt% Na 2 O). However, given the consistent sodium loss on archaeological glass surfaces due to deterioration, we chose to look for characteristic wood ash glass features including elevated phosphorous, calcium, magnesium, and potassium combined with low chlorine concentrations.…”

Micro‐X‐ray fluorescence (XRF) screening of 244 glass sherds from Ribe, Denmark, identified 23 wood ash glasses. The closely dated finds pinpoint the arrival of the earliest wood ash glass produced in Western Europe in this important North Sea trading hub. This glass type was absent among glass from 700 to 790 CE but feature strongly from 790 to 810 CE. Electron microprobe analysis (EMPA) and laser ablation inductively coupled plasma mass spectrometry (LA‐ICP‐MS) analysis of 24 glasses show the presence of four types. We show the strengths of classifying wood ash glass based on the glass‐producing sands and conclude that the earliest production took place on a considerable scale and had a major impact on glass circulation in Northern Europe in the ninth century.

“…Principal component analysis (PCA) of XRF data were used to determine the chemical groups (Glascock et al, 2004) in the investigated archaeological materials (Origin 2017 statistical software tool was applied). Because of the risk of post-deposition contamination, P 2 O 5 was not included in the research (Freestone, 2001).…”

Neolithic burial pottery from the Jiaojia site, China: A multi‐analytical study

2022

View full text Add to dashboard Cite

The present study focuses on middle and late Dawenkou Culture burial pottery—cookware, drinking ware, and tableware—recently unearthed from the Jiaojia site. Through the application of X‐ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), and X‐ray diffraction (XRD), we have revealed for the first time that the compositional difference of Jiaojia burial pottery is related to the category and function of wares. Calcium‐poor clay was used for cookware and tableware, whereas calcium‐rich clay was used for drinking ware. The pottery body's mineralogical assemblage and chemical composition results point to the careful selection and preparation of raw materials and oxidizing fire temperatures between 750 and 950°C. In most cases, the temperatures used for firing drinking ware were generally higher than those used for firing tableware and cookware.

“…These walls appear to be the most recent phase of the investigation area. The discovered opus reticulatum wall structure can be dated between the first century BC and the first century AD [6]. This wall construction is not related to the reported production complex, but rather to an aristocratic villa, indicating a change in the intended use of the area from residential to work/productive purposes.…”

Archaeometric Investigations on Archaeological Findings from Palazzo Corsini Alla Lungara (Rome)

This study reports the analytical investigations on clayey and ceramic finds, characterised by high variability in terms of prime materials, with the aim to determine the role of this important ceramic production situated close to the city walls, fortuitously found during service excavations developed in the garden of Palazzo Corsini in Rome. The complexity of the finds led to the choices of appropriate methodologies and techniques suitable for defining the diagnostic elements of each find. Optical microscopy (OM) combined with micro-Raman (µ-Raman) spectroscopy, X-ray diffractometry (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDS), and differential thermal analysis (DTA) were used to analyse the nature and microstructure of the ceramic and burned clay that were found. In such a complicated setting, the objective of conducting chemical analyses is to provide clues to describe the various kinds of ceramics produced, the production and processing methods, and, as a result, the typology of the workshop.
