From Faraday to the nanotechnology: the difficult relationship between chemistry and restoration

LB in collaboration with the CTS of Altavilla Vicentina
Thursday November, 8 from 4:00 p.m. to 4:45 p.m. - Saletta Rosi
Cavaniglia Pavilion, Fortezza da Basso, Florence

The relationship between chemistry and restoration has ever been difficult and controversial. Some of the substances used in the recent past years, as for example the so called “beveroni” or the “mixed poultices” remember us a sort of dark alchemist's Cave.
Only in the sixties, producers begun to commercialise some products and technologies, properly designed for restoration, together with the development of the diagnostic analysis techniques applied to artworks.
It will be also discussed some opportunities given by some recent studies conducted in various science and restoration as for example the method for barium, the ion-exchange resins, the fluoride polymers, while examining the inevitable passage from the “Chemistry of restoration” to the last frontier of the nanotechnologies.
The word nanotechnology is a sort of fashion word and it is used only in a minimum part in our sector. Some of the researches on the nano calcium has followed a long period of experimental applications in few pilot restoration sites with a careful final analysis of the results, as for example in the case of the caso Nanorestore; in some other cases the final results of the application of products “Nano”, has been considered inefficient or even harmful.
