Production Technology and Provenance of Dvāravatī Glass Beads from Khu Bua, Central Thailand: An Archaeometric Study
The production technology and provenance of 22 beads from the Dvāravatī-period site of Khok Phithak at Khu Bua, central Thailand (6th–11th centuries CE), was investigated using a multi-analytical approach combining VP-SEM-EDS, LA-ICP-MS, and micro-Raman spectroscopy. Macroscopic and microstructural evidence indicates that most of the glass beads were manufactured by the drawn-tube method, consistent with the supply of imported Indo-Pacific beads …
Try It Before You Buy It: A Non-Invasive Authenticity Assessment of a Purported Phoenician Head-Shaped Pendant (Cáceres, Spain)
Museums may acquire archaeological artefacts discovered by non-specialists or amateur archaeologists, holding the potential to promote the safeguarding of cultural heritage by integrating the local community in their activities. However, this also creates an opportunity for the fraudulent sale of modern forgeries presented as archaeological artefacts, resulting in the need for a critical assessment of the artefact’s authenticity prior to acquisit…
An Archaeometric Analysis of Black-Appearing Iron Age Glass Beads from Vinha das Caliças 4 (Portugal)
Phoenician colonisation of the Iberian Peninsula in the 1st millennium BCE introduced many novel and luxurious goods to the local populations of the Western Mediterranean. Among them, black-appearing glass beads are characteristic of indigenous female burials in Southern Portugal during the 6th century BCE. This study presents the results of the first comprehensive archaeometric investigation of black-appearing glass from Vinha das Caliças 4 (Por…
Optimization of the Application of Commercial Hydrophobic Coatings for Natural Stone Protection and Preservation
Natural stone has been used worldwide in the construction of archaeological and historical heritage. However, its preservation continues to be threatened by weathering and degradation phenomena. Water is widely recognized as the most threatening external component that contributes to stone deterioration, increasing the need for the development of protective hydrophobic coatings to eliminate water penetration. This study intends to contribute to t…
A multi‐analytical approach applied to pottery from Oman as a key to understanding ancient Indian Ocean maritime trade
The populations in Sumhuram (third/second century bce to fifth century ce ) and Hamr al‐Sharqiya 1 (HAS1) (first millennium bce to first/second century ce ) were involved in one of the most important examples of large‐scale trade systems in antiquity: the maritime network connecting the coasts of the Indian Ocean. This research focuses on a total of 35 southwestern Arabian and Indian pottery sherds from both the settlements of Sumhuram and Hamr a…
Unveiling the Effectiveness of Innovative Commercial Coatings Used for the Preservation of Natural Stone—A Contribution
The preservation of natural stone heritage is still a major challenge for the scientific community. This topic assumes a greater importance since it impacts economic and socio-cultural values. Recent research has indicated that water action and microorganism activity are among the major contributors to the deterioration of this material. Despite the emergence of new protective solutions in the market, some constraints still need to be overcome. T…
Personal adornments in West-Central Africa-the case study of a talc bead from the Kongo Kingdom (Mbanza Kongo, Angola)
A mustard-gold-colored talc bead was recovered during the 2014 excavation campaign carried out in Lumbu (Mbanza Kongo, Angola) together with the nineteenth-century glass trade beads imported from Bohemia and Venice. Results from this multi-analytical and minimally invasive study suggest that this bead may have been brought to the kingdom's capital by means of an established intra-kingdom trade network or as an offering intended for the king or a …
New approaches for the study of faience using beads from Southern Portugal
A collection of 30 faience beads recovered from the Iron Age necropolis of Vinha das Caliças 4 (Beja, Portugal) was analyzed in order to identify their production technology and provide insights into their possible provenance. The multi-analytical approach employed, combining laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), variable pressure scanning electron microscope coupled with energy dispersive X-ray spectrometry (VP…
Lithic arrowheads: Siliceous raw material sources and technology in Southern Portugal
This analysis focused on one hundred and fifteen lithic arrowheads recovered from the Zambujeiro and Mitra 2 dolmens, funerary monuments in Évora, Portugal. These were analyzed by noninvasive and minimally invasive analytical techniques, including handheld X‐ray fluorescence (hXRF), variable pressure scanning electron microscope coupled with energy dispersive X‐ray spectrometry (VP‐SEM‐EDS), and laser ablation inductively coupled plasma mass spec…
The Islamic Ceramic of the Santarém Alcaçova: Raw Materials, Technology, and Trade
This study focuses on the analysis of Islamic ceramics from the Alcaçova of Santarém, Portugal. To establish the ceramic raw material provenance and ceramic technology, a set of raw materials was sampled and compared with the archaeological ceramics. Raw materials were dry sieved to increase the clay content, to reconstruct the ceramist homogenization process, and to evaluate chemical and mineralogical variation. Results showed that two raw mater…
