The conservation of cultural heritage is most challenging. In areas like West Asia where prolonged internal conflict and attacks on tremendously valuable cultural heritage sites are ongoing, conservation may even seem hopeless at times. Therefore my immediate and honest answer to the question of this paper’s title is ‘no’. Basically, conservation science is a field that aims to study archaeological, artistic or architectural cultural materials based on the use of scientific methods for identifying creative techniques and causes of deterioration. It also aims to distinguish suitable methods and materials for conserving cultural heritage through study of the causes of deterioration, measures for improving materials, and techniques for conservation.

The European Synchrotron Radiation Facility (ESRF) has recently commissioned the new Extremely Brilliant Source (EBS). The gain in brightness as well as the continuous development of beamline instruments boosts the beamline performances, in particular in terms of accelerated data acquisition. This has motivated the development of new access modes as an alternative to standard proposals for access to beamtime, in particular via the “block allocation group” (BAG) mode. Here, we present the recently implemented “historical materials BAG”: a community proposal giving to 10 European institutes the opportunity for guaranteed beamtime at two X-ray powder diffraction (XRPD) beamlines—ID13, for 2D high lateral resolution XRPD mapping, and ID22 for high angular resolution XRPD bulk analyses—with a particular focus on applications to cultural heritage. The capabilities offered by these instruments, the specific hardware and software developments to facilitate and speed-up data acquisition and ...

Synchrotron-based Fourier transform infrared micro-spectroscopy (SR-FTIR) is one of the emerging techniques increasingly employed for Cultural Heritage analytical science. Such a technique combines the assets of FTIR spectroscopy (namely, the identification of molecular groups in various environments: organic/inorganic, crystallized/amorphous, solid/liquid/gas), with the extra potential of chemical imaging (localization of components + easier data treatment thanks to geographical correlations) and the

Since 2004, scientific research on the damaged Giant Buddha statues and Buddhist paintings in Bamiyan, Afghanistan, has been conducted at various laboratories and large-scale facilities using mass-spectrometry techniques (GC-MS, LC-MS, LC-MS/MS, nano-LC/ESI-MS/MS), ELISA, and synchrotron-based micro-analyses) in parallel to conservation intervention. Studies on samples from these cultural heritage objects have shown that each is composed of a polychromatic multilayered structure with sizing layers, ground layers, painted layers, and glaze. The carefully produced complex multilayered structures were examined using optical microscopy (visible and UV light) as well as synchrotron-based infrared microscopy, both of which revealed various organic and inorganic components in each layer. High sensitivity bulk MS and ELISA methods were used to further identify details regarding organic materials, such as fatty acids and collagens, and these results suggest different vegetable oils and anima...

Abstract The Uzumlu Church is an unusual soft tuff formation located in central Turkey (Cappadocia) dated around the 7th century. The rocks on its external surfaces show a severe erosion with an evident surface detachment. Moreover, the widely distributed black-grey crusts mainly consisting of lichens point out the need of evaluating their deteriorative effects. This research was focused on lichen deterioration by indicating the biodeterioration processes and on selecting the most appropriate preservation treatments suitable for stone conservation. The interaction of lichens with stone was studied by evaluating through microscopic analyses, the spread and the depth of fungal hyphae penetration, and by applying the LPBA Index. The SEM analysis of all fragments shows a dramatic loss of the stone matrix and a dense network of fungal hyphae within the rock. Nevertheless, both the high penetration of fungal hyphae, and the consequent difficulty in their removal without a strong peeling effect, both the relevant loss of the stone matrix and finally the evident reduction of water penetration when crusts are present in the surfaces, advise against their removal. Further chemical treatments of consolidation should be carefully evaluated.

Digital documentation is one of the most useful techniques to record the condition of cultural heritage. Recently, high-resolution images become increasingly useful because it is possible to show general views of mural paintings and also detailed mural conditions in a single image. As mural paintings are damaged by environmental stresses, it is necessary to record the details of painting condition on high-resolution base maps. Unfortunately, the cost of high-resolution photography and the difficulty of operating its instruments and software have commonly been an impediment for researchers and conservators. However, the recent development of graphic software makes its operation simpler and less expensive. In this paper, we suggest a new approach to make digital heritage inventories without special instruments, based on our recent our research project in Üzümlü church in Cappadocia, Turkey. This method enables us to achieve a high-resolution image database with low costs, short time, ...

is published by Morana RTD d.o.o. www.Morana-rtd.com e-PRESERVATIONScience This paper is based on a presentation at the sixth international meeting of the Users'Group for Mass Spectrometry and Chromatography (MASC) in Pisa, Italy, 5th – 6th June 2013. Abstract Romano-Egyptian panels in the collections of the J. Paul Getty Museum dating to 180-200 A.D. were found to contain proteinaceous paint media. Animal glue was detected in the ground layers of all three panels using Enzyme-linked immunosorbent assay (ELISA) and mass spectrom-etry. Results were verified with gas chromatography/mass spectrometry (GC/MS) by the identification of 4-hydroxyproline, the major amino acid that occurs in animal glue collagen but not egg albumin. The animal species used to make the glue was identified as cow (Bos taurus) by using nano-liquid chromatography-electrospray ionization-tandem MS (nanoLC-ESI-MS/MS). A paint fragment from the Bearded Man contained tryptic peptides, type III collagen α1 chain,...

Three turquoise-blue beads from a Syrian neolithic site, Tell el-Kerkh, were investigated by micro X-ray fluorescence, Fourier transform infrared spectroscopy, X-ray diffraction, spectrophotometry and scanning electron microscopy. The results from the analyses and laboratory experiments indicated that the blue beads were an alternative to and imitation of natural turquoise beads. They are formed of an apatite core with a turquoise colour obtained probably by the heating of manganese or iron compounds. The microstructure and chemical composition of the beads indicate the use of mammal tooth or tusk, possibly 'odontolite' (fossil ivory). The technique used to produce these blue beads is a precursor to the development of glazing.

The analysis of cultural Heritage objects is often technically challenging. When analyzing micro-fragments, the amount of matter is usually very tiny, hence requiring sensitive techniques. These samples, in particular painting fragments, may present multi-layered structures, with layer thickness of ˜10 μm. It leads to favor micro-imaging techniques, with a good lateral resolution (about one micrometer), that manage the discriminative study of each layer. Besides, samples are usually very complex in term of chemistry, as they are made of mineral and organic matters, amorphous and crystallized phases, major and minor elements. Accordingly, a multi-modal approach is generally essential to solve the chemical complexity of such hybrid materials. Different examples will be given, to illustrate the various possibilities of synchrotron-based micro-imaging techniques, such as micro X-ray diffraction, micro X-ray fluorescence, micro X-ray absorption spectroscopy and micro FTIR spectroscopy. Focus will be made on paintings, but the whole range of museum objects (going from soft matter like paper or wood to hard matter like metal and glass) will be also considered.
