Numismatic survey update and archaeometric technique integration

  By

The bibliographic survey of the numismatic finds from Tuscany within the ERC nEU-Med project, related to the period between the 7th and mid-14th century, aimed at the creation of a finds database (and their relative context), has almost reached completion. At the same time, the insertion of unpublished numismatic material found at the sites investigated by the Department of History and Cultural Heritage from the sites of Miranduolo, Campiglia M.ma, Canonica di S. Niccolò, Castel di Pietra, Cugnano, Donoratico, Montemassi,… Continue reading

New laboratory analyses on “vetrina sparsa”

  By

The progression of the study on “vetrina sparsa” pottery led to a thorough selection of fragments for the preparation of the samples to submit to lead isotopes analyses. We are currently collaborating with Dr. Igor Maria Villa, member of the Institut für Geologie of the University of Berne (Switzerland) and the Centro Universitario Datazioni e Archeometria at the University Milano-Bicocca, who mainly takes care of the geo-chronological dating on geological materials and isotopic analysis (Sr, Pb) on geological and archaeometric… Continue reading

archaeometric analyses on “vetrina sparsa” samples from the archaeological site of Donoratico

  By

Coatings from selected samples were investigated in order to characterize their main chemical and textural features and to acquire data to be compared with results from previous studies on samples from the same repertory (Fortina et alii, 2008). The use of polarized light microscopy allowed investigating the textural and mineralogical features of the coatings, such as thickness, color, presence and distribution of bubbles, cracks and discontinuity. The chemical and mineralogical composition of both coatings and relics, together with the interaction… Continue reading

Archaeometric analysis of selected metal artefacts from the site of Vetricella

  By

Archaeometric analysis of selected metal artefacts from the site of Vetricella has been conducted at the Wolfson Archaeological  Laboratories of the UCL (University College London) Institute of Archaeology (Fig.1). Objective of the study is to better comprehend the metalworking traditions adopted in the area between the 9th and 11th centuries AD as well as the nature of the resources employed in the production of metal objects.

Archaeometric study on pottery between Colline Metallifere and Tyrrhenian sea

  By ,

An archaeometric study on pottery from different archaeological sites (Capalbiaccio, Colle Massari, San Martino in Piano, Rocchette Pannocchieschi, Donoratico, Castellina, Rocca degli Alberti and Casa Andreoni) located in south-western Tuscany (in a territory within the Colline Metallifere and the Tyrrhenian Sea) is carried out in the framework of the nEU-Med project promoted by the Department of History and Cultural Heritage of the University of Siena (UNISI). The study is focused on the characterization of some ceramic samples associated with small… Continue reading

Archaeometallurgy at Vetricella

  By ,

Several samples of metallurgical slags and some metallic fragments have been found during the last excavation campaignat Vetricella (Scarlino). The analysis of these materials (metallography, chemistry and mineralogy) can help to define what type of metal production/working was conducted in the site. Moreover the distribution of metallurgical wastes could identify the areas devoted to smithing/smelting, which will be the target of next excavations. All these analysis will be performed at the Department of Earth Sciences, University of Florence. As evidenced… Continue reading

Prof. John Mitchell and the analisys on metals found in Vetricella site

  By ,

This week Prof. John Mitchell ,an art historian from the University of East Anglia (UEA) , is studying and analyzing the metals found in Vetricella (Scarlino) site at the lab of Dipartimento di Scienze Storiche e dei Beni Culturali  dell’Università di Siena(Fig.1). His researches are very important for nEU-Med project to understand the type and function of these findings. Continue reading
