TL;DR: In this article, the characterization results of artists' alkyd paints using THM (thermally assisted hydrolysis and methylation) gas chromatography-mass spectrometry (THM-GC/MS) and Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) were presented.

TL;DR: In this paper, the authors show that the sandstone used in the construction of the Church of San Mateo in Tarifa (Cadiz, Spain) is highly sensitive to processes of decay because of a combination of factors that are intrinsic and extrinsic to the material.

TL;DR: In this article, a 16th C. wall painting in the church of Agios Sozomenos in Galata, Cyprus was analyzed using micro-FTIR in reflectance for spot analysis of areas on the surface of an embedded cross-section, and FTIR reflectance imaging for the localisation of the presence of copper and calcium oxalates within the stratigraphy of the painting.

TL;DR: In this paper, the authors reviewed the physico-chemical studies published on such varnishes and also focused on a research project carried out since 2002 at the Musee de la musique in Paris, which aims to apply in a comprehensive way different non-destructive or micro destructive methods (Py-GC/MS, IR microscopy, SEM/EDX, EDXRF, synchrotron radiation-based techniques, etc.) to the study of a large and representative number of ancient varnished musical instruments from a museum collection.

TL;DR: In this paper, the values proposed by various standards for the thermal environment of museum buildings have been revised and the indoor microclimatic conditions relating to people's comfort have been described, with the aim of singling out possible common ranges for these parameters.

TL;DR: In this paper, the effect of impregnation with Paraloid B-72, using the protocol commonly followed in museum restoration departments, on the mechanical and water absorption properties of Portuguese tiles from XVI to XXth centuries, was studied.

TL;DR: In this paper, an electrochemical realkalization treatment was applied to eight columns on the bell tower of a tower built in the 1920s, where a traditional repair (based on substitution of carbonated concrete with a repair mortar) would have been practically impossible.

TL;DR: In this paper, the chemical characterisation of the paint medium was performed through an analytical procedure based on GC-MS, and the proteinaceous binder was identified for the first time through a desalting procedure used in proteomics.

TL;DR: In this paper, the application of a new class of organogels as cleaning tools for painted surfaces is described, which combines some of the most attractive features of cleaning liquids and normal gels while diminishing the deleterious characteristics of both.

TL;DR: In this paper, nanocomposite systems based on the commercial polymer Fluormet CP and different amounts of the Cloisite 30B organoclay (1, 2 and 4 ) were tested as protective and consolidating agents for the Neapolitan yellow tuff.

TL;DR: In this article, an integrated archaeological sciences project concerning Egyptian cultural heritage with a threefold aim: (a) the multifold analysis of construction material (granite, limestone, sandstone, gypsum), providing new data, (b) a detailed radioactivity survey of the monuments, and (c) the development of a new optical stimulated luminescence dating approach for limestone buildings.

TL;DR: In this paper, the authors apply the choice experiment technique to an archaeological site to investigate and estimate the value visitors place on various attributes of the site, and present a questionnaire requiring visitors to make choices between scenarios containing various pre-determined options for the management and content of a site.

TL;DR: In this paper, the corrosivity of 19 different indoor environments was investigated by the use of lead coupons, by an adapted methodology from ISO 11844 using weight measurements The field test was carried out in storage areas of real museum and archive buildings Parallel with the 3-month exposures of the coupons, climate and pollutants H2S, SO2, and organic acids were measured only relative humidity and organic acid showed individual linear correlation with the formation of corrosion mass.

TL;DR: In this article, a comparison of the process to develop ruby glass with the conventional ones is discussed and a small purple-red 17th century glass vase was also studied and it was found to contain only manganese as the colouring agent; in this case the colour is due to electronic d-d transitions.

TL;DR: In this article, a qualitative and quantitative approach to natural lighting design for historical buildings, in this particular case study used as a public library, was proposed for the old library of Palagio di Parte Guelfa in Florence, was based on solar radiation control and advanced daylight system application (two light shelves, a sky light and two light pipes).

TL;DR: In this article, a ground-penetrating radar (GPR) survey was carried out on the Roman theatre of Sagunto (Valencia, Spain) following recent restoration work in 1991.

TL;DR: In this paper, the effects of biocide application on a water-repellent film and the possibilities to restore the efficiency of the previous water repellent treatment (after the application of the biocide) were investigated.

TL;DR: In this paper, the effects of atmospheric deposition on the cement mortar of the basement in a building located in the city of Ancona (Italy) were evaluated by combining visual observation, scanning electron microscopy, X-ray diffraction, ion chromatography, differential and gravimetric thermal analysis and quantitative determination of elemental carbon.

TL;DR: A detailed study of beaker fragments from the site of Lubieszewo (type locality for the so-called Lubsow-tombs in Poland) yielded a range of interesting information about glass quality and especially the use of opacifying pigments.

TL;DR: In this article, a differential model was applied to give a quantitative description of the diffusion and the chemical action of sulphur dioxide on the porosity of calcium carbonate stones starting from the hypothesis that the interaction between stone surface and polluted air is due to its diffusion in the material.

TL;DR: In this paper, the shrinkage temperature values of the investigated materials, determined by DSC analysis of the samples immersed in water, are in good agreement with those determined by Micro Hot Table technique.

TL;DR: In this paper, the pigments, the binders and the materials used for the application of ground and priming layers were studied using micro-Raman spectroscopy, gas chromatography coupled with mass spectrometry (GC/MS), optical and electronic microscopies.

TL;DR: The campus of the College of Industrial Engineering of Barcelona was recently declared an Architectural Heritage Site due to the value of its Modernista buildings, which were built in 1868 under the direction of the architect Rafael Guastavino (1842-1908) as mentioned in this paper.

TL;DR: A geophysical survey was performed at the Roman Amphitheatre of Catania with the aim to study the lithological features of the foundation subsoil of the amphitheatre and to identify possible underground voids, buried crypts and other heterogeneities as mentioned in this paper.

TL;DR: In this article, the authors evaluated the actual conditions and their stability inside closed vessels and found better sealing materials (gaskets and caps) than those recommended by the ASTM D6819-02e3 standard for testing the accelerated ageing of paper.
