Abstract A portable energy‐dispersive x‐ray fluorescence (EDXRF) equipment was used to measure pigments and precious metal composition. From the spectra it also possible assign each pigment correct layer, in case of sheets (e.g. gildings) identify layer distribution. Several methods have been developed determine thickness layers sheets. They were specifically applied gold Giotto's halos Chapel Scrovegni Padua, gilded copper objects from Royal Tombs Sipán Museum Sicán. Copyright © 2008 John...
Many objects of common use (tools, utensils, metals, knick‐knacks, dishes and glasses) artifacts (for example paintings all types) are composed two or more layers. In many cases, it would be useful to determine the correct location, composition thickness various Non‐destructive non‐invasive methods described, based on energy‐dispersive X‐ray fluorescence which able ‘reconstruct' complete structure a multilayered sample. These use, in different ways, ratios characteristic X‐rays emitted by...
When investigating gilded artifacts or works of art, the determination gilding thickness plays a significant role in establishing restoration protocols conservation strategies. Unfortunately, this is done by cross-sectioning object, destructive approach not always feasible. A non-destructive alternative, based on differential attenuation fluorescence radiation from sample, has been developed past years, but due to intrinsic random nature X-rays, study single few spots an objects surface may...
In this work, we studied the manufacturing processes and conservation state of gilt painted leather fragments from Palazzo Chigi in Ariccia (Italy) by using different analytical techniques. Leather present a silver leaf superimposed onto support. A gold varnish layers decorate it all. top-down approach was used to investigate complex multilayer structure, which adopted techniques with sampling depths. Organic inorganic constitutive materials together related degradation products were time...
The use of X-ray fluorescence (XRF) scanning systems has become a common practice in many application sectors. In multistratified and heterogeneous samples, the simple analysis an XRF spectrum as response entire sample is not reliable, so different spectral techniques have been proposed to detect presence surface stratification. One commonly studied case that gilding, i.e., superimposing gold-leaf layer. observation changes net peak ratios single element or several elements well-developed...
A modular X-ray scanning system was developed, to fill in the gap between portable instruments (with a limited analytical area) and mobile large areas, sometimes bulky difficult transport). The scanner has been compared commercial tabletop instrument, by analysing Portuguese tile (azulejo) from 17th century. Complementary techniques were used achieve throughout characterisation of sample complete non-destructive approach. complexity acquired fluorescence (XRF) spectra, due inherent...
Traditional Serbian religious art originated in Byzantine culture and conserved elements until modern times. However, since the end of 17th century, many changes traditional icon painting have been introduced. Previous studies focused on iconography style, but very little attention was paid to materials techniques. This research focuses blue pigments icons from first half 18th century. Eight with areas a different hue were selected for study. Due its rarity nature, price, iconographical...
Abstract This work addresses the authenticity issue of fake potteries circulating in illicit art market, imitating ancient artefacts, by an interdisciplinary and a multi‐analytical approach. In faking manufacture, unscrupulous forgers use increasingly advanced skills to mimic materials technologies produce artificial ageing. Despite phenomenon archaeological objects' forgery is considered crime source earnings, there are not enough works literature support difficult unmasking objects. this...
Abstract The investigation of archaeological and historical materials makes use techniques that, though borrowed from other fields research industrial production, frequently have to be ‘re‐invented’ because peculiar characteristics the analysed objects. Artistic relevance, limited movability, compositional structural heterogeneity radically change experimental approach often require ad hoc designed equipment. These considerations also apply x‐ray fluorescence, especially regarding mobile...
Abstract An important part of the world's cultural heritage is represented by stone monuments. A very dangerous weathering process that deteriorates monuments and caused human activity air pollution. One worst pollutants for associated with sulfur compounds, especially gypsum. Gypsum a rather soluble compound may be washed away rain. It leaves surface clean but eroded open to new corrosive processes. With transportable energy dispersive x‐ray fluorescence (EDXRF) instruments it possible...
Field Portable Energy Dispersive X Ray Fluorescence (FP-EDXRF) is particularly useful to analyze works of art, mainly because his noninvasive and multielemental capability. In many situations FP-EDXRF the only non invasive technique that can be realistically used gain some information about chemical composition precious unique objects. Many kind works, such as paintings, bronzes, metals alloys, inks, stones, stamps more studied using a field portable EDXRF system. This manuscript highlights...
The paper presents the results of multi-analytical study painting on a panel from icon collection Gallery Matica srpska museum in Novi Sad, Serbia. It is part research aiming to set methodology for museum’s database artistic materials and techniques present collection. Computer tomography (CT) scanning was used understand structure wooden support. Ultraviolet (UV) infrared (IC) imaging, as well visible (VIS) macro photography, were paint layer, both original restoration treatments, coat...
During the last years research for new scintillation crystals has been crucial improvement of imaging performance in nuclear medicine applications. Crytur company recently released two scintillators named CRY-018 and CRY-019 which are non hygroscopic, have short decay time low refraction index. They represent ideal candidates to substitute NaI:Tl BGO future PET ad SPECT The purpose this work is characterize unknown crystals, look possible applications medicine. results were compared with...
Pinhole gamma camera imaging offers the ability to obtain high resolution images from single ray emitting radiotracers playing a reasonable tradeoff between very small field of view (FoV) and sensitivity. On other hand total spatial pinhole device is predominantly affected by detector intrinsic for reduced magnification factors. To design compact SPET scanners with resolution, authors investigated miniature based on newly developed Hamamatsu H8500 flat panel photomultiplier. The PSPMT was...
