Abstract of the intervention: 

 

Restoration

The intervention on the monument of Angelo Brofferio, owned by the city of Turin, was carried out in several stages. The first phase, carried out in December 2018, included a preliminary study aimed at deepening the executive technique, the state of conservation and the presence of previous interventions. The study was flanked by a diagnostic campaign that made it possible to characterize some of the constituent materials, over-mixed substances and degradation products. The results of this intervention have been merged in a first report, in a series of graphic mappings and in an account of the scientific analyses carried out. 
The second phase consisted in the intervention of real conservative restoration, conducted as part of a summer educational site with the students of the fourth year of the degree course in Conservation and Restoration of Cultural Heritage. 
The intervention included biocidal treatment, cleaning and consolidation tests and cleaning from deposits. Subsequently, a second biocidal treatment was carried out and consolidation operations were carried out at the fracture on the hand and microcracks.
Finally, the altered groutings were removed and overhauled, grouting was carried out ex novo, then painted with watercolors. 
On the base, after the cleaning and consolidation phases, the graffiti was removed and the epigraph retouched in the areas affected by abrasion. 
At the end, an anti-scratch product was applied and an intervention was carried out on the steps (cleaning, application of herbicide, grouting of the joints).
