Abstract: Stone monuments represent an important part of our world´s cultural heritage. The awareness of increasing stone damage on monuments and the danger of irretrievable loss of cultural heritage have resulted in great efforts worldwide for sustainable monument preservation. A precise damage diagnosis with the comprehensive characterization, interpretation and rating of stone damage represents the basis for effective and economic monument preservation measures. The experienced methodological approach to the assessment of stone damage combines in situ investigation and laboratory studies. The monument mapping method is presented as an established non-destructive procedure for in situ studies on stone damage. It can be applied to all stone types and to all kinds of stone monuments. The use of weathering forms, damage categories and damage indices for the registration, documentation, quantitative evaluation and rating of stone damage is explained. Furthermore, complementary in situ measurements are discussed. A wide range of analytical procedures and weathering simulation tests contribute to modern damage diagnosis on stone monuments.Keywords: damage, stone, monumentsResumo: INVESTIGAÇÃO SOBRE DANOS DO INTEMPERISMO PARA MONUMENTOS EM PEDRA. Os monumentos em pedra representam uma parte importante do patrimônio cultural do mundo. A consciência do aumento dos danos causados ao material pétreo nesses monumentos e o perigo de perda irrecuperável desse património resultaram em grandes esforços a nível mundial para a preservação sustentável desses monumentos. Um diagnóstico preciso de danos com a caracterização, interpretação e avaliação abrangentes desses danos causados às pedras representa a base para a adoção de medidas de conservação eficazes e econômicas. A abordagem metodológica a ser adotada para a avaliação desses danos deve combinar a investigação in situ e estudos laboratoriais. Nessa abordagem o mapeamento de monumentos é apresentado como um procedimento não destrutivo estabelecido para os estudos in situ sobre danos causados às pedras, podendo ser aplicado a todos os tipos de pedra e a todos os tipos de monumentos construídos com a pedra. Nesse trabalho, o uso de formas de intemperismo, categorias de danos e índices de danos para o registro, documentação, avaliação quantitativa e classificação de danos para a pedra é explicado. Além disso, discutem-se medidas complementares a serem adotadas in situ. Uma ampla gama de procedimentos analíticos e testes de simulação de meteorização contribuem para o diagnóstico de danos modernos em monumentos construídos em pedra.Palavras Chave: dano, pedra, monumentos

This paper reports the analyses carried out on the medieval copper alloy door (1111–1118 AD) of the mausoleum of Boemondo d’Altavilla in Canosa di Puglia (Southern Italy). The studied door is the smallest medieval bronze door extant in Italy and, unlike the other Byzantine doors, was most probably made in Canosa di Puglia and not in Constantinople. Analyses were performed to assess the chemical composition of the alloy patinas using a portable energy dispersive X-ray fluorescence (ED-XRF) instrument designed at the University of Salento. The experimental results suggested that the two door leaves have the same chemical composition, even if they appear different in both style and size. Furthermore, the alloy used for the door is different from the other previously-analyzed Byzantine bronze doors. The obtained results can be used in the future to compare the chemical composition of other Byzantine doors in order to better understand the manufacture of these precious artifacts.

A new method for in-situ studies of nucleation in bulk metals based on high energy synchrotron radiation is presented. Copper samples cold rolled 20% are investigated. The crystallographic orientations near triple junctions are characterized using non-destructive 3DXRD microscopy before, during, and after annealing for 1 hour at 290°C. This method allows in-situ identification of new nuclei and the deformed material, which spawns the nuclei. Also, since data is acquired during annealing nucleation kinetics can be studied.

Analysis Protocol

Among the possible variants of X-Ray Fluorescence (XRF), applications exploiting scanning Macro-XRF (MA-XRF) are lately widespread as they allow the visualization of the element distribution maintaining a non-destructive approach. The surface is scanned with a focused or collimated X-ray beam of millimeters or less: analyzing the emitted fluorescence radiation, also elements present below the surface contribute to the elemental distribution image obtained, due to the penetrative nature of X-rays. The importance of this method in the investigation of historical paintings is so obvious—as the elemental distribution obtained can reveal hidden sub-surface layers, including changes made by the artist, or restorations, without any damage to the object—that recently specific international conferences have been held. The present paper summarizes the advantages and limitations of using MA-XRF considering it as an imaging technique, in synergy with other hyperspectral methods, or combining it with spot investigations. The most recent applications in the cultural Heritage field are taken into account, demonstrating how obtained 2D-XRF maps can be of great help in the diagnostic applied on Cultural Heritage materials. Moreover, a pioneering analysis protocol based on the Spectral Angle Mapper (SAM) algorithm is presented, unifying the MA-XRF standard approach with punctual XRF, exploiting information from the mapped area as a database to extend the comprehension to data outside the scanned region, and working independently from the acquisition set-up. Experimental application on some reference pigment layers and a painting by Giotto are presented as validation of the proposed method.
