Opificio delle pietre dure
The Opificio delle pietre dure, literally meaning Workshop of semi-precious stones, is a public institute of the Italian Ministry for Cultural Heritage based in Florence. It is a global leader in the field of art restoration and provides teaching as one of two Italian state conservation schools (the other being the Istituto Superiore per la Conservazione ed il Restauro). The institute maintains also a specialist library and archive of conservation and a museum displaying historic examples of pietre dure inlaid semi-precious stones artefacts. A scientific laboratory conducts research and diagnostics and provides a preventive conservation service.
The second branch of the Institute (laboratori di restauro) had a more modern story. In 1932 Ugo Procacci, the distinghished scholar of Florentine art, in his career as an officer of the Italian Ministry for Cultural Heritage, founded a Laboratory of restoration (original Italian name: Gabinetto di restauro) at the Florence Soprintendenza. It was the first modern restoration laboratory in Italy (pre-dating of 7 years the Istituto Superiore per la Conservazione ed il Restauro in Rome) and one of the very first ones in all the world. The Gabinetto di Restauro used scientific methods for the preliminary exhaminition of the works of art (as X radiography) and began an outstanding campaign of restoration on Tuscan Early Masters paintings, that was later known as "restauri di rivelazione" (literally meaning revealing restoration).
In 1966, the fatal tragedy of the flooding of the River Arno, resulted in many priceless works of art requiring restoration. It provided a significant impetus for expansion of the Gabinetto di restauro's research and restorative services. More space was needed because of the sheer number of artworks which required restoration and also, in some cases, the large size of the pieces themselves, such as the immense 4.48 x 3.9m Crucifix by Cimabue from the Basilica di Santa Croce. The expansions provided new laboratories in the Fortezza da Basso. Thanks to financial aid and an influx of expertise from throughout the world, the Florentine Laboratory became, in a short time one of the vanguard restoration laboratories in the world, combining traditional practices with modern technology.
In 1975, the Cultural Heritage Ministry merged the Opificio laboratories with the Gabinetto di restauro (plus other minor Florentine restoration laboratories) and created a new Institute, the modern Opificio delle pietre dure.
Today, the institute is organised in departments specific for the various types of artworks it treats. The laboratories are in three principal venues: in Via Alfani 78, in the historic centre of Florence; in the Fortezza da Basso; and in Palazzo Vecchio where restoration treatments on tapestries and textiles are carried out. There are also several research and services offices.
The actual (updated on march, 26, 2012) Superintendent is Marco Ciatti. The Opificio has a board of directors of the departments, under the supervision of the Supertintendent. It has also a gestional committee and a scientific committee.
