Challenges in laser cleaning of cultural heritage stained glass

1 January 2022

The article discusses the challenges associated with laser cleaning of stained glass surfaces in cultural heritage conservation. Stained glass windows hold significant cultural value but are prone to damage from various factors. The study explores the use of short-pulse lasers, specifically femtosecond laser systems, for safe and controlled cleaning of stained glass. Different laser frequencies and pulse energies were tested to manage heat accumulation and prevent chemical damage during the cleaning process. The research aimed to develop cleaning protocols that would avoid mechanical and chemical harm to the glass surfaces,

Air and wall mycobiota interactions – a case study in the Old Cathedral of Coimbra

1 January 2022

The text discusses the impact of fungal microbiota on historical monuments, focusing on the Old Cathedral of Coimbra. It highlights the presence of diverse fungal species in the air and biodeteriorated stone within the chapels, emphasising the specificity and environmental requirements of these isolates. The study reveals that the air serves as a vector for spreading fungal propagules, potentially leading to biodeterioration and health risks for visitors and staff. The research underscores the importance of collaboration between biologists and conservation teams to develop preventive measures against biological contamination in heritage

Vernacular Caramel’s Adobe Masonry Dwellings – Material Characterization

1 January 2022

The article discusses the importance of characterising adobe materials from existing constructions, particularly focusing on Caramel’s dwellings for potential rehabilitation. It highlights the lack of standardised testing methods for historic adobe masonry constructions, emphasising the need for test standards to homogenise procedures and increase knowledge in earth construction methods. Laboratory testing was conducted on adobe samples from three case studies, assessing properties such as bulk density, ultrasonic pulse velocity, thermal conductivity, abrasion resistance, strength, capillary absorption, and drying behaviour. The study reveals variations in the properties of adobe samples from

The “Ferradeira” individual burial of Herdade do Álamo (Beja): facets of social change in the late 3rd millennium BC in South Portugal

1 January 2022

The article explores the “Ferradeira” individual burial at Herdade do Álamo in South Portugal, shedding light on social changes during the late 3rd millennium BC. The burial site, located near Beja airport, was excavated revealing a pit grave with an individual in a foetal position oriented North-South. The burial included metallic objects like a dagger and arrowheads, indicative of the period’s funerary practices. The study integrates archaeological, bioanthropological, isotopic, and archaeometallurgical analyses, contributing to understanding this relatively obscure transitional period in the Iberian Southwest. The individual buried was a middle-aged

Archaeometric Study Of The Proto-Historic Ceramics From The Settlement Of The Avecasta Cave (Ferreira Do Zêzere, Portugal)

1 January 2022

The article presents an archaeometric study focusing on proto-historic ceramics discovered in Avecasta Cave, Portugal. The ceramics analysed date back from the Late Neolithic to the Iron Age, showcasing fragments of bowls and vases. The study utilised various analytical methods such as Optical Microscope (OM), X-ray Fluorescence (XRF), X-Ray Diffraction (XRD), and Scanning Electron Microscope coupled to Energy Dispersive Spectrometer (SEM-EDS) to examine the samples. Additionally, Helium gas Pycnometer was employed to determine the physical properties of the ceramics. The research identified different fabric types used in the production of

Analytical characterization of academic nude paintings from the Faculty of Fine Arts of the University of Lisbon

1 January 2022

This study focuses on the analytical characterization of 20 academic nude paintings from the Faculty of Fine Arts of the University of Lisbon, created between 1899 and 1918. The research combines in situ non-invasive methods such as infrared reflectography, radiography, and EDXRF with laboratory microanalytical techniques including micro-Raman, micro-FTIR, and SEM-EDS. By analysing these paintings, insights into the artistic practices of the late 19th and early 20th centuries at the Academy of Fine Arts of Lisbon are provided. The study involved the examination of painting materials and pigments used in

New data on the Late Bronze Age / Early Iron Age metallurgy in Central Portugal. The contribution of Vila do Touro (Sabugal, Guarda)

1 January 2022

The article focuses on new data regarding Late Bronze Age/Early Iron Age metallurgy in Central Portugal, specifically at Vila do Touro. Metal artefacts, including a forged sheet, fibula, stem, ring, and belt hook, were excavated and analysed for their elemental composition. The study utilised X-Ray Fluorescence spectrometry, Scanning Electron Microscopy with X-ray Microanalysis System, and optical microscopy to characterise the metal objects. The results revealed varying compositions, indicating a mix of pure copper, binary bronze (Cu+Sn), leaded bronzes (Cu+Sn+Pb), and gold. The Ossa Morena region in Southwest Iberian Peninsula was

Cuidar para valorizar. Estratégias de preservação no âmbito do Mercado da Arte

1 January 2022

The study delves into the intersection of conservation and restoration guidelines with the practicalities of the art market, particularly focusing on contemporary art in Portugal. By analysing professional guidelines against market objectives and gathering insights from art market agents, the research aims to develop balanced diagnostic models for conservators. The personal testimonies collected offer valuable empirical insights, enriching the study’s syntheses and the need for diagnostic guidelines that consider both the artistic and economic dimensions of artworks in the commercial context emerges as a key finding. The study highlights the

Stärkung der reslienz des kulturerbes gegen den klimawandel

1 January 2022

This report addresses the intersection of European heritage and climate change, presenting key findings and recommendations for policymakers, heritage managers, and society as a whole. It emphasises the European Green Deal’s goal of achieving climate neutrality by 2050 and the need to integrate cultural heritage into climate change initiatives. The document highlights the vulnerability of cultural heritage to climate change and the potential of heritage preservation as a sustainable solution to the climate crisis. One of the main themes explored is the impact of climate change on European cultural heritage.
