Caracterização química, mineralógica e textural das cerâmicas do Bronze Final d...

Este estudo, ainda que preliminar, envolveu a caracterização arqueométrica de cerâmicas atribuíveis a contextos do Bronze Final do Sudoeste, provenientes de escavações arqueológicas levadas a cabo no povoado fortificado do Passo Alto e no povoado aberto de planície da Salsa 3. Estes sítios arqueológicos encontram‐se implantados em áreas geologicamente distintas – gabro‐dioríticas, a Salsa 3, e xistosas, o Passo...

Testing the harmfulness of chemical cleaning methods for the removal of incrust...

ncrustations are a common conservation problem, particularly in artworks exposed to water. Calcium-rich layers tend to build over their surface making cleaning interventions necessary to improve the chemical stability and restore readability. Harmfulness tests are crucial for selecting cleaning methodologies for glazed surfaces due to their mechanical and chemical susceptibility. This study selected a combinati...

Sand and Pebbles: The Study of Portuguese Raw Materials for Provenance Archaeol...

Portuguese archaeological excavations dated to the 17th century onwards are extremely rich in glass artefacts, with this being a reality from the north to the south of the territory. Contrasting with this reality, no glass production locations from this period have been discovered or excavated so far, which makes the provenance attribution a challenging endeavour. One specific archaeological location, the Monas...

ABSTRACT: Chinese blue-and-white porcelain is found in archaeological excavations worldwide, being significant evidence of global trade routes and cultural exchange. Synchrotron radiation-based techniques have been applied for studying cobalt speciation to establish a correlation between the cobalt and iron oxidation state and local coordination environment in the rich blue shades of Chinese blue-and-white porc...

Faux marble of the Church São Luís dos Franceses (Lisbon): condition, character...

This article makes known the research on the internal wall renders of the Church São Luís dos Franceses, with paintings on the stucco imitating marble, the so-called faux marble. They have been executed between 1766 and 1769. The study characterizes the faux marble, performed by the technique Stucco Lustro. In this context, we examined their condition and characterized this covering, using several analytical te...
