Study on the effects of chemical cleaning on pinaceae resin-based varnishes from panel and canvas paintings using pyrolysis-gas chromatography/mass s…

Abstract Cleaning of varnish coatings is one of the most critical steps in the restoration treatment of paintings and characterization of physical and chemical processes involved in this practical procedure has attracted interest of scientists in the field of conservation. Evaluation of chemical cleaning methods based on the application of organic solvents and detergents on Pinaceae resin-based varnishes from panel and canvas paintings has been successfully carried out using pyrolysis-gas chromatograpy/mass spectrometry (Py-GC/MS). The proposed method includes the on-line derivatization of the diterpenoid resin using hexamethyldisilazane (HMDS). Analyses performed on a series of model varni…
Analytical study of canvas painting collection from the Basilica de la Virgen de los Desamparados using SEM/EDX, FT-IR, GC and electrochemical techni…

A new method, based on the combined use of scanning electron microscopy-x-ray microanalysis, Fourier transform infrared spectroscopy, gas chromatography and differential pulse voltammetry, is proposed which permits a parallel investigation of organic and inorganic materials and the characterization of the artistic technique employed in canvas painting. The proposed method has led to analyze succesfully the canvas painting collection exhibited in the Basílica de la Virgen de los Desamparados (Valencia, Spain) which includes art works from 17th to 20th century.
SCIENTIFIC INVESTIGATIONS FOR THE RESTORATION OF SANTA CHIARA FROM THE SANTA CATERINA D’ALESSANDRIA MONASTERY IN PALERMO, ITALY
2022
The aim of this research was to assess the techniques and the materials used to realize the canvas painting Santa Chiara, from the Santa Caterina d’Alessandria Monastery and to verify the state of preservation, the possible decay processes and previous restorations. Consequently, an integrated analytical approach based on the use of non-invasive (diffused, indirect and ultraviolet light investigations) and micro-invasive techniques (optical microscopy, OM, scanning electron microscopy, SEM-EDX, Fourier- transform infrared spectroscopy FT-IR spectroscopy) were used. The oil painting on canvas dated XVI century: data suggests traditional painting technique, characterized by two priming prepar…
