Virtual reconstructions have become widely established as communication and research tools in the context of architectural and urban studies. To make these reconstruction solutions more transparent and to allow for their assessment and recognition, it is of vital importance to document and evaluate the reconstruction processes. However, currently, such documentation, which would facilitate the scholarly analysis of the results, is only compiled in isolated cases. The DFG-funded project IDOVIR (Infrastructure for Documentation of Virtual Reconstructions) provides the community with an open,...

In recent years, the control of the microclimate in museums has assumed a role of great importance. The deterioration process, defined as a result of progressive and cumulative material decay, depends on environmental variables and their changes. In particular, inappropriate temperature and relative humidity levels speed up the chemical and physical deterioration and may cause irreparable damage to cultural artefacts. This research focuses on state of conservation assessment of 34 plaster casts of Trajan's Column of the Museum of Roman Civilisation and on the microclimate monitoring of the...

This paper presents an objective methodology for clustering the indoor microclimate of a multi-room cinematographic archive housing climate-sensitive film materials. The proposed methodology was tested on a selected case study: an archive housing cellulose acetate films located in the Mediterranean area. A multivariate statistical approach (cluster analysis) was used to identify clusters of rooms from temperature and relative humidity observations recorded continuously in the archive’s storage rooms over a 7-month period. The outputs of this work led to a reduction from 26 rooms to four...

This contribution presents the analysis of environmental data collected over the 2016-2022 period in the Hall of the historic building of Villa Blanc in Rome, Italy, with ceiling and walls hardwood paneling. Data related to three different sub-periods (during the retrofit, after 1 and 5 years from the retrofit) were analyzed in detail. Based on the ASHRAE 2019 Guidelines, it was found that thermo-hygrometric data differ among the sub-periods (specifically in the years 2016-2017, data are outside the limits of the 5th-95th multi-year band), however there is no marked risk of mechanical damage...

Archives, museums, libraries can have quarantine rooms as storage areas in which incoming collections are temporarily housed (i.e., from 2 weeks to 40 days). The purpose of the quarantine period is to control the object’ state in case of appearance of signs suggesting ongoing chemical and biological alteration, before being placed in conservation or exhibition spaces. Inappropriate thermo-hygrometric conditions of such spaces could negatively affect the conservation state of organic materials commonly stored in archives. In this paper, the indoor climate characterisation of a quarantine...

One of the current challenges facing restorers and conservators of cultural heritage is to ensure the right balance between treatment efficacy, long-term conservation and reduced environmental impact. Certain cases, such as that of the Nymphaeum of Villa Giulia in Rome, in which the three elements cross each other, sometimes making the balance very difficult. The Nymphaeum of Villa Giulia in Rome, designed by the architect Bartolomeo Ammannati in the mid-16th century, is characterized by a complex architectural apparatus and is enriched by refined decorations in stucco, stone materials and...

This research represents the first non-invasive analytical study on the wall paintings of the Domus del Ninfeo (1st century B.C.) excavated in Cremona. Scientific analysis played a crucial role in investigating the pigments and the painting technique that contributed to a deeper understanding of one of the provinces of ancient Rome in Northern Italy. To this aim we utilized portable X-ray fluorescence (XRF) combined with FTIR spectroscopy in external reflection mode (ER-FTIR) for characterizing the wall decorations. The outcomes revealed that wall paintings were executed using the fresco...

In past decades, interest in using nanomaterials for the preservation of valuable cultural heritages was rapidly increased due to their excellent properties. In the present study, a biomimic method for the consolidation of sandstone (i.e. Serena stone) by hydroxyapatite was investigated. The strategy is to mimic the growth of bone like crystals: calcium (as Ca(OH)2 nanoparticles) and phosphorus (as diammonium hydrogen phosphate) are introduced into stone substrate and then, mineralized in-situ at room temperature. Before the treatments, Ca(OH)2 nanoparticles have been synthesized and...

The present paper summarizes the fundamental results of the study and restoration of the gilded stucco decoration of the Lante Della Rovere Chapel of Palazzo Orsini in Bomarzo (Viterbo), which was the subject of a master's thesis in Conservation and Restoration of Cultural Heritage at University of Tuscia. The diagnostics was fundamental for understanding the executive technique and investigating the problems relating to the state of conservation of the artefact. It was performed by in situ non-invasive techniques such as ultraviolet fluorescence photography and X-ray fluorescence...

The aim of the research presented in this paper is to monitor the stability of three protective products applied on samples of Peperino stone, a volcanic tuff widely used for the historic buildings and architectural elements in Viterbo (Italy), using portable devices. More in detail, two different monitoring techniques were applied: VIS-NIR point spectroscopy (400-1000 nm), and colorimetry. In order to characterize the compositional variability and homogeneity of the samples, X-ray micro-fluorescence (micro-XRF) was preliminary used. Data were acquired before and after the application of the...
