Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

The Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Technologies of Transition: Pottery Production and Specialization in Early Rome and Its Neighbors. Neutron Activation Analysis of Regional Assemblages and a Mineralogical‐Petrographic Study of Impasto Chiaro‐Sabbioso

Archaeometry, EarlyView.
ABSTRACT The following paper investigates ceramic production and signs of specialization in Rome and the wider region during the early first millennium bce, through an archaeometric approach using Instrumental Neutron Activation Analysis (NAA), and complementary techniques.

An Uncommon Instance of Egyptian Blue in the “Pigmented Intonachino” of the Fishpond Wall Painting From the Roman Villa of Torre di Pordenone (Northeast Italy)

Archaeometry, EarlyView.
ABSTRACT The increasingly close integration of analytical techniques in the study of Greek and Roman wall paintings has shown that Egyptian blue was a common pigment, widely documented in the production of blue and greenish hues in ancient painted production.

An Experimental Approach on Pearl Shell (Pinctada margaritifera) for a Microwear Study of Shell Artefacts From French Polynesia

Archaeometry, EarlyView.
ABSTRACT Pinctada margaritifera (black‐lipped pearl oyster) artefacts are ubiquitous in the archaeological record throughout the Pacific and particularly in Polynesia. Despite efforts towards the development of typologies, the lack of microwear and use‐wear studies has prevented the development of technological approaches. We used 20 pearl shell valves

Exploring Use‐Wear Texture Quantification Through Confocal Microscopy on Tools Made From Volcanic Rocks (Basalt and Phonolite)

Archaeometry, EarlyView.
ABSTRACT Functional analysis is essential for reconstructing lithic tool use. Recent approaches combining confocal microscopy and surface texture analysis provide quantitative alternatives to traditional visual use‐wear analysis, although their application to coarse‐grained, heterogeneous rocks remains challenging because of their complex surface ...
