Several studies indicate that the decay of medieval stained glass windows is related to both composition and characteristics environment. The kinetics processes has been always described through experiences performed in aqueous confined conditions, which are obviously not encountered real condition. A research programme set up order assess atmospheric weathering. long short term weathering studied respectively ancient fragments analogues exposed field. This paper presents preliminary results...
Abstract Stained glass windows are a precious heritage to pass on future generations. However, medieval stained particularly altered due their chemical composition and the effects of climatic (mainly water temperature), environmental (pollution) biological factors. In this review, we present alteration patterns observed ancient Si-K-Ca windows. To better understand formation mechanisms determine rates, different exposure campaigns current atmosphere in position sheltered from rain or not...
Abstract Over the last decade, hyperspectral imaging has become a popular technique for non-invasive identification and mapping of painting materials in many typologies artworks, thanks to possibility obtaining spectral information over spatial region. A few attempts have also been made on stained-glass windows identify chromophore elements responsible glass color. Hyperspectral stained can be complex; most cases, are an integral part buildings, sunlight represents natural light source...
The development of innovative solutions to reduce hydrogeological risk is one the most important research topics recent years. paper proposes a technique for river flood detection based on image processing sub-blocks. tests carried out with proposed method have shown that system able estimate flooding event good precision and very short timeframes. activity was within CORA (COntrollo del Rischio Ambientale, Environmental Risk Control) project financed by Calabria Region (Italy) <sup...
Stained-glass windows are very particular artifacts; they not only have an intrinsic artistic and historical meanings, but also a functional role, strictly connected to the buildings where were originally placed.The investigation of these artifacts is challenging research opportunity, due their optical, chemical physical characteristics.However, properties could change with time, depending on raw materials used, or exposure in aggressive environment.For this reason, developing imaging...
Whatever the chemical composition and origin (natural or man-made) surrounding environment is, glass materials undergo alteration processes leading to modification of their structure composition. Similar patterns can be observed in different historical types, especially layers characterized by a laminated structure. The study medieval stained windows (14th century AD, from Northern France) Roman blocks (2nd shipwreck Mediterranean Sea) with several centuries exposure atmospheric marine...
Low durable glasses, used in medieval stained-glass Northern Europe, usually display a poor conservation state. To preserve them, research strategy taking into account the atmospheric environment and material was conceived to better understand their degradation. The comparison between ancient model glass undertaken. results show that due rain, condensation pollutants undergoes scaling cracks. After introducing state of art this article, analytical techniques will be detailed, then main...
Reflectance Transformation Imaging (RTI) is a multi-light imaging technique using camera on fixed position and orthogonal to the studied surface, while varying light for each image captured. This allows reconstruction of surface's visual appearance characterization surface by providing additional information deformations local micro-geometry. RTI was applied historical model glass corroded in presence volatile organic compounds (VOCs) visualize early stages corrosion. used create relighting...
Abstract In the previous paper (Part I), colorimetry and interferometric microscopy measurements on modern gold leaf models have revealed that visual appearance of a gilded surface, both burnished unburnished, depends strongly substrate type, surface roughness texture, but not colour substrate. this second part, we investigate materials compositions technical specifications medieval through combining literature sources analysis such as scanning electron coupled with energy dispersive X-ray...
