A Multi-Analytical Archaeometric Approach to Chalcolithic Ceramics from Charneca do Fratel (Portugal)
The archaeological site of Charneca do Fratel, in Vila Velha de Ródão, Portugal, is a fortification that is radiocarbon-dated from the third millennium BCE. The archaeological fieldwork in 1987 revealed the first Chalcolithic settlement on the northern Portuguese bank of the Tagus River. Its architectonic concept is similar to that observed in southern Portugal, proving new insights into the study of the process of Chalcolithisation of western Ib…
Archaeological Ceramic Fabric Attribution Through Material Characterisation—A Case-Study from Vale Pincel I (Sines, Portugal)
Defining groups of ceramic objects from archaeological excavations is a crucial and primary practice in the study of settlements, providing information related to ceramic technology, provenance, and interactions, among others. This process begins with a macroscopic analysis of each fragment, identifying common features to define ceramic fabrics. Regularly, this procedure requires further analytical techniques to refine the attribution of each cer…
Historical lime‐based flooring mortars from the Church of Santa Maria de Alcobaça monastery (12th century), Portugal
The Monastery of Alcobaça houses in reserve the ceramic tiles that adorned the floor of the church's apse. These tiles were removed during rehabilitation works and many preserve part of their original fixing mortars. A comprehensive analysis of 21 samples was conducted using a multi‐analytical approach (X‐ray fluorescence, X‐ray diffraction, scanning electron microscopy–energy‐dispersive X‐ray spectroscopy, μ‐Raman spectroscopy, thermogravimetry–…
Decay products of historical cements from the Palace of Knossos, Crete, Greece
The Palace of Knossos, located on the island of Crete, Greece, is one of Europe's most important archaeological sites, serving as a testament to the Minoan civilization. Situated near the Mediterranean Sea, it is in close proximity to the seaport, airport, and industrial areas. Decay products commonly found in historical monuments within or near urban areas, such as black crusts and salt efflorescence, are also prevalent at the Palace of Knossos.…
Later prehistoric tin mining in the Ervedosa mine (Vinhais, Portugal)
Contribution to the Understanding of the Colour Change in Bluish-Grey Limestones
Bluish-grey limestones have been extensively used as ornamental stones for decoration purposes in buildings, as well as in works of art, and accordingly, have been the target of intense exploration. In Portugal, the Jurassic limestone massif known as the Maciço Calcário Estremenho (MCE), has been the source of grey-coloured ornamental stones, namely the Azul Valverde (one of the most well-known bluish-grey limestones) and Atlantic Blue varieties,…
Characterization of Chalcolithic Ceramics from the Lisbon Region, Portugal
The Chalcolithic period in the Lisbon region, Portugal, is usually divided into three phases chronologically: the Early Chalcolithic, characterized by cylindrical corrugated cups, Full Chalcolithic by so-called acacia-leaf decoration, and Late Chalcolithic by Bell Beaker pottery. The aim of this research is to determine if Chalcolithic ceramic raw materials and production techniques have remained the same over time and whether the pottery is loca…
The Case Study of the Medieval Town Walls of Gubbio in Italy
Good conservation and restoration practices of cultural heritage assets rely on the knowledge of original materials. In the framework of the HERACLES Project (HERACLES—HEritage Resilience Against CLimate Events on Site, H2020 Grant Agreement 700395), dealing with the effects of climatic actions and natural hazards on built heritage, a set of important heritage sites are currently under study to improve their resilience against climate events. Amo…
