The pictorial decoration of the church of Santa Maria La Porta in Geraci Siculo. Critical historical analysis of the canvases and frescoes. Iconographic readings, stylistic analysis and attributions
Indagine termografica degli affreschi nella Chiesa di Santa Maria della Catena a Palermo
2009
Il testo descrive l’applicazione sperimentale di una nuova metodologia analitica diagnostica basata sullo svolgimento sinergico del rilevamento fotogrammetrico e dell'indagine termografica delle superfici architettoniche. La ricerca si pone l'obiettivo di caratterizzare lo stato di conservazione degli affreschi all’interno della Cappella Maggiore nella Chiesa di Santa Maria della Catena a Palermo attraverso l'elaborazione della diagnosi che risulti specifica per la redazione del progetto di conservazione e la direzione del relativo cantiere d’intervento. L'applicazione scientifica è svolta nell'ambito della sperimentazione della nuova Metodologia T.R.U.E. e del relativo software.

A smartphone-based innovative approach to discriminate red pigments in roman frescoes mock-ups
2022
The characterization of red pigments in frescoes wall paintings has been of great interest for researchers to better understand raw material procurement dynamics, pigment receipts, stylistic evolution and to assess their conservation state. In this study a non-destructive colorimetric approach implementing a smartphone-based method was developed in order to be able to distinguish between three pigments made from minium, haematite and cinnabar minerals, and also mixed pigments, preparing frescoes mock-ups following the roman receipt described by Vitruvius. Portable FT-IR, Raman spectroscopy, portable XRF and visible reflectance spectra analyses were carried out as reference methods for smart…
A Raman spectroscopic and combined analytical approach to the restoration of severely damaged frescoes: the Palomino project
2008
The deterioration of art objects is normally relatively minor, controllable and attributable to environmental changes or bacterial invasion, and until now there has not been any recorded attempt to analyse an artwork that has been deliberately and significantly destroyed. The analytical problems are correspondingly larger but the potential reward from any information that can be forthcoming is thereby proportionately greater. The 17th Century Palomino frescoes on the vaulted ceiling of the Church of Sant Joan del Mercat in Valencia were largely destroyed by insurgents in the Spanish Civil War in 1936. The ensuing gunfire and a series of seven conflagrations inside the church had a devastati…
Analysis of pigments from Spanish works of art using a portable EDXRF spectrometer
2002
Nowadays there is an intensive program for the conservation, restoration and analysis of the impressive and extensive Spanish cultural heritage. In the last few years, the Unidad de Arqueometria of the ICMUV has carry out a great quantity of in situ EDXRF analysis of pigments on materials of historic and cultural interest (altarpieces, frescoes, canvas, sculptures, etc.) from museums and churches of the whole of the Spanish geography. Here we present a few examples of the analysis of works of art using x-ray fluorescence spectrometry with a portable system based on x-ray tubes and a non-cryogenic Si-PIN detector. EDXRF qualitative and non-destructive analyses of stone, pigments and preparat…
Agri-food Supply Chain Traceability for Fruit and Vegetable Cooperatives Using Blockchain Technology
2019
Blockchain se ha convertido en una tecnología disruptiva que tiene la capacidad de transformar la industria agroalimentaria, puesto que promete resolver muchos problemas relacionados con la falta de confianza en la trazabilidad y el producto que adquieren los consumidores. Sin embargo, las partes implicadas en la cadena de suministro de productos agroalimentarios son numerosas y están físicamente dispersas, lo que dificulta el manejo de datos e información. Como resultado, el proceso de producción no es transparente y la confianza es difícil de construir. Para ser más exitosas en la economía globalizada actual, las cooperativas deben focalizarse en ofrecer mayor transparencia. Este document…
Identification of Earth Pigments by Applying Hierarchical Cluster Analysis to Solid State Voltammetry. Application to Severely Damaged Frescoes
2007
Multivariate chemometric methods are applied for identifying earth pigments from square-wave voltammetric measurements performed at pigment-modified paraffin-impregnated graphite electrodes allowing for a separation between hematite-based earths, French ochres, Spanish ochres, siennas, umbers and green earths. This methodology is applied to the identification of the pigments in samples from the ceiling frescoes of Antonio Palomino (dated 1707) in the vaulted nave of the Sant Joan del Mercat church in Valencia (Spain). These frescoes suffered considerable damage by fire during the Spanish Civil War in 1936, resulting in severe chemical and chromatic alterations. Electrochemical data, support…
Nuevas consideraciones sobre el pintor Francesco Pagano
2010
En este artículo se presentan dos documentos inéditos relacionados con la pintura al fresco de los ángeles músicos de la catedral de Valencia realizada por Francesco Pagano y Pablo de San Leocadio. Se trata de un inventario de bienes perteneciente a Francesco Pagano y un documento relativo a los andamios utilizados para la ejecución de los frescos. Su interpretación permite reconsiderar el papel asignado a ambos pintores y aporta nuevas hipótesis sobre el proceso de ejecución de esta obra. (A)
