The present work is part of a PhD project entitled Archaeometry of ceramic artefacts. Innovative tools and solutions for the knowledge, diagnostics and conservation of ceramic finds from archaeological contexts, concerning the study, the analysis and the application of innovative, effective and sustainable solutions for the knowledge of the archaeological heritage related to ceramic artefacts from medieval archaeological contexts in Basilicata, aimed at the compositional characterization of ceramic bodies and their coatings, including decorative elements when present. Here are reported the...

The Graffita ware from the Moliterno Castle showed compositional peculiarities (relative to both ceramic body and glaze-decoration) that give indications on the technologies used for the itsproduction in Basilicata and on the circulation of raw materials. Different technologies seem to have been adopted for the production ofGraffita ware in the diyacrony. There is a Graffita ware characterized by a lead coating with traces of tin, containing abundant quartz and cristobalite, implying firing at high temperatures. The bright green decoration consists of a copper-based pigment with aggregates...

In the 1980s, in the locality of S. Andrea a Travo (Piacenza), a Neolithic settlement, datable between 4300 and 3800 B.C., was found, which represents one of the most important sites in northern Italy in terms of dwellings and structures. In the area furthest from the river and the houses, there were 23 hearths with burnt stones, which, according to chemical analyses, were used for cooking meat. However, a number of slabs were also found in the hearths with shapes and features that suggest rough anthropomorphic stelae; in particular, the one with dark traces is the main focus of this work....

The archaeological site of Eynan, located by the spring of Ain Mallaha and on the shores of Lake Hula in the Upper Jordan Valley, Israel, existed for several millennia at the end of the Pleistocene. During the Natufian culture of the Levantine Epipalaeolithic, the site was one of the largest known occupations in the Levant for some millennia (ca. 14,300 -11,900 cal BP). Remains of Natufian architecture were found, together with evidence of early experimenting with pyrotechnology for the creation of lime plaster. Several features were identified during the excavations as assumed lime plaster...

The present work shows the preliminary results of an archaeometric study involving a group of tiles and bricks dated back to the late 3rd-1st century BC, found in the archaeological site of Scala Coeli, Terravecchia and Cariati, in the province of Cosenza (Calabria, Southern Italy). The materials were analyzed by Optical microscopy, X-ray Powder Diffraction and Energy Dispersion Microanalysis by Scanning Electron Microscope, to identify the composition of the samples, the area of extraction of the raw materials and the technological aspects related to the processing of the clay. The...

Two of a group of thirty coins dating between to 1st century BC and 1st century AD, found in the so-called Grotta delle Ninfe near Cerchiara di Calabria (Calabria, Italy), and preserved in the display case of the Brettii and Enotri Museum in Cosenza (Calabria, Italy) have been under archaeometric investigation. This paper aims to understand the oxidation processes, know constituent material and find hidden signs or inscriptions on the coins by means of X-ray fluorescence (XRF) portable spectrometer and X-ray microtomography (X-ray u-CT) in order to make the hypothetical inscriptions...

This investigation concerns the characterization of plasters samples taken from archaeological vats from production installations for fish by-products from the archaeological site of Portopalo in Sicily (Italy). The main purpose of this work is to characterize the plasters in order to understand if specific plasters production technologies were used in relation to the function of the vats and if there is a change in time/space among the vats studied that apparently belonged to different phases of occupation of the site. The compositional characterization of the distinct types of materials...

A high precision calibration method, based on extreme value measurement, data storage, fast sampling and the simulation of actual use state, for new-type pulse wave lightning protection component tester was proposed after analyzing working principle and difficulties of measurement. This method replaced the conventional measurement method, reading method and sampling method for constant wave, ensured the accuracy of calibration at the same time, and realized the calibration of constant current, initial operating voltage, DC leakage current and DC breakdown voltage of the tester. This method...

Magnetic measurements are vital to support European challenges in areas such as electric vehicles; health; power transformation and harvesting; clean, affordable and secure energy; information and sensor technology. However, only very few European NMIs have the capabilities to perform traceable measurements of all of the most important magnetic quantities. Consequently, the adoption of novel technologies and materials is hindered by the lack of local metrological expertise that research and development activities in academia and industry could exploit. A new European project (TRaMM,...

The surface impedance of superconductors in function of intense (~ 10 T) static magnetic field at varying orientations with respect to the crystallographic axes is of large interest for both characterization purposes, in view of the material engineering, and from the point of view of devices to be used in fundamental physics experiments. A varying field orientation is customarily obtained with mechanically rotating magnets, whose complexity limits the attainable maximum fields to a few T. Here we propose a special proof of concept design for a measuring cell in which the magnetic field...
