Mostrare l’invisibile: il soffitto trecentesco nascosto del convento di Santa Caterina a Palermo
2022
Digital surveying and representation technologies have been widely used for the visualization of works of art and architecture that no longer exist or have been moved from their original location. These researches share a common feature, that can be resumed by the motto “Display the invisible”, already used in research experiences [Colosi et al. 2015; Gambin et al. 2021]. The purpose of this research is the visualization of a 14th century wooden ceiling, painted by anonymous artists, that covered the hall used for the assembly of the Chapter in the convent of Santa Caterina, at the heart of the historic center of Palermo. The hall was reshaped at the end of the 18th century to serve as a sa…
Investigation on a low environmental impact solvent mixture applied to a wooden painted slab
2016
Cleaning is one of the most complex and delicate step in a restoration project, often due to the manufacturing techniques of the artifacts and their advanced state of decay. Eco-friendly solvents can permit to execute the cleaning operations with a reduced health impact for the restorers and for the environment. In this work, the performance of the 1,3- dioxolane/methylal (DIOX-MET) solvent mixture is evaluated over a wooden painted slab that had been covered with a thin layer of a protective varnish, probably during a previous conservation work performed in the Sixties. Removal of this varnish has been considered on behalf of its yellowing degradation process, which caused chromatic change…
Sperimentazione di una procedura per la creazione di un atlante digitale per la documentazione dei soffitti lignei dipinti di Sicilia
2021
The naves of churches and the halls of noble palaces. The paintings that decorate these ceilings are precious evidence of the wide cultural connections that linked Sicily to Europe and to the Mediterranean area. The paper reports the results of research aiming at the development of a workflow for the creation of a digital atlas of these ceilings. Digital representation overcomes one of the main obstacles to the study, the preservation and the dissemination of these works of art, i.e. the traditional dichotomy between photographic images and drawings. The chosen case study is the ceiling that covers the main hall of the Steri in Palermo, a 14th-century palace that today hosts the offices of …
Multi-technical approach for the characterization of polychrome decorative surfaces at Spanish Mission Churches in Nueva Vizcaya (Chihuahua, Mexico)
2020
An interdisciplinary and multi-institutional group of science and art conservation specialists has provided new insight into the painting materials used in the polychrome walls and wooden ceilings in four seventeenth century Spanish colonial churches of Nueva Vizcaya (Chihuahua, Mexico). A multi-analytical study of the decorative surfaces was performed in situ using spectroscopic approaches (XRF, FORS), False Colour Infrared Reflectography – IRFC, as well as micro sampling for ATR-FTIR, LM and GC/MS laboratory analyses. A survey of natural resources were also studied by ATR-FTIR and LM to elucidate the natural occurrence of a select number of materials found in the surrounding areas of the …
A multi-disciplinary investigation of the "Tavolette fuori posto" of the "Hall of Barons" wooden ceiling of the "Steri" (Palermo, Italy)
2016
Abstract Four painted slabs, called “Tavolette fuori posto” (Slabs out of place), of Galleria Interdisciplinare Regionale della Sicilia — Palazzo Abatellis (Palermo, Italy) were investigated with multi-techniques approach by using noninvasive and micro-destructive techniques. The slabs presumably belong to the decoration of the wooden ceiling of the “Hall of Barons” of the Palazzo Chiaramonte, said Steri, in Palermo (Italy). The aim of this study was to investigate the kind of materials used by the artist, the executive technique and the state of conservation. Pigments, binders and trace of previous restorations were identified. The results were used to properly plan the restoration interve…
Wooden domes, vaulted and flat ceilings, partition walls in the Sicilian constructive tradition knowledge for the safeguard of architecture abd techn…
2014
The domes, vaulted and flat ceilings and also the partition walls built with wood and reeds had a particular diffusion from the XVII century, in Palermo as well as in other countries of Sicily, in many regions of Italy and in the whole Europe. The consolidated constructive tradition made them one of the most appreciated and usual systems for structural frame and for the definition of interior rooms, employed both for the monumental housebuilding and for that of minor importance, also owing to the adoption of economic materials. These wooden structures in the monumental architecture contain the rich pictorial and stucco decoration and define - together with other aspects of quality - the aul…
