This work aims to study these materials, considering their functions, especially as structural elements or as...
A Multi-Analytical Archaeometric Approach to Chalcolithic Ceramics from Charnec...
Saraiva, Ana S.; Coutinho, Mathilda L.; Soares, Joaquina; Tavares da Silva, Carlos; Caninas, João C.; Veiga, João PedroThe archaeological site of Charneca do Fratel, in Vila Velha de Ródão, Portugal, is a fortification that is radiocarbon-dated from the third millennium BCE.

Coutinho, Mathilda; Veiga, João Pedro; Ruivo, Andreia; Pereira da Silva, Teresa; Bottura-Scardina, Silvia; R. A. Lima, Maria Margarida; Pereira, CarlosFábrica de Loiça de Sacavém (ca. 1858–1994) was among the first to produce white earthenware in Portugal, becoming one of the country’s leading ceramic manufacturers during the late 19th to early 20th centuries. Research on white earthenware has accompanied the growing interest in post-industrial archaeology but is still poorly explored compared to more ancient ceramic productions. This study focused on the cer...

Alexandra; Coutinho, Mathilda; Salas-Colera, EduardoBluish-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 lime...

Ancient tin production: Slags from the Iron Age Carvalhelhos hillfort (NW Iberi...
Figueiredo, Elin; Fonte, João; Lima, Alexandre; Veiga, João Pedro; Silva, Rui J.C.; Mirão, JoséProvenance and production of tin in the Ancient World has since long been a major topic of discussion among archaeologists. In Western Europe, where significant tin ore (cassiterite) deposits are known, only a few remains of ancient tin production, such as tin slags, have been detected. In the present work, elemental and microstructural analyses by WDXRF, SEM-EDS and XRD were performed on recently recognised ti...
