Abstract

This paper aims to demonstrate the usefulness of digital reconstructions in the visualization and interpretation of analytical data obtained in science conservation projects. The study was carried out in the Tomb of the Monkey, one of the most important tomb of the Etruscan necropolis of Poggio Renzo, near Chiusi, dated around 480-470 BC. Photogrammetry survey method was used to generate a 3D model of the whole underground grave. The main advantage of this method, which is based on dense stereo matching tools, is the possibility to generate 3D reconstruction starting from a set of uncalibrated images, with non invasive and easy transportable hardware. Open source software is also used to integrate 3D wall painting data to the diagnostic researches: (I) Multispectral analysis, able to improve the readability of the painted scenes, detecting details otherwise invisible to the human eye, and (II) X-Ray Fluorescence data that give information on the elemental composition of materials and confirms the behavior of the multispectral signals collected on the wall painting surfaces.

Abstract

In this work, nanomaterials were used as consolidants and protective layers for artistic stones. Synthetized nanocomposites were applied on marble and their performances as protective and water repellent coating were characterized. For the preparation of the novel nanocomposites, SiO2 and TiO2 nanoparticles were synthesized by laser pyrolysis and were dispersed in acrylic polymer and silicon-based resin. To evaluate the retreatability of water repellent treatments, the capability of laser to remove protective layers was explored. Laser cleaning tests with different working parameters have been carried out to optimize the effectiveness of the process. The effects of laser treatments on stone surfaces and on the applied nanocomposites were estimated by using confocal optical microscopy and Laser-Induced Fluorescence (LIF).

Abstract

Properties of consolidant and protective materials modified with nanoparticles were analysed in this study following their application onto marble samples. For this purpose, different solutions of an acrylic resin with dispersed SiO2 and TiO2 nanoparticles were prepared. The relative durability of Paraloid B72, an acrylic resin used as consolidant and modified by nanoparticles, was evaluated comparatively by means of diverse diagnostic techniques, namely, scanning electron microscopy, laser-induced fluorescence, ultrasonic sound, colorimetry, total immersion water absorption and contact angle. The results demonstrate that nanoparticles enhance the effectiveness of consolidant and protective material because they induce substantial changes of surface morphology of the coating layer.

Abstract

In this work, the effectiveness of nanocomposite surface treatments as protective systems for artistic stones was evaluated. Pyrolitic silica and titania nanoparticles were dispersed in a commercial silicon-based polymer and applied on marble and travertine samples. Artificial aging processes, both in climatic chamber and in solar box, were carried out to simulate real degradation processes in terms of photo-thermal effects and physical-chemical damage. The performances of the nanocomposites used as consolidant were evaluated comparatively by means of diverse diagnostic techniques, namely: scanning electron microscopy (SEM), laser induced fluorescence (LIF), ultrasonic technique, colorimetry, total immersion water absorption and contact angle. The results show that some properties of conservation materials can be improved by the presences of nanoparticles because they induce substantial changes of surface morphology of the coating layer and counter the physical damage observed during artificial weathering. © 2014 AIP Publishing LLC.
