BAPTISTERY OF SAINT JOHN - FLORENCE
CLEANING OF PART OF THE MARBLE FAÇADE

The restoration of the Baptistery in Florence was a conservative act aimed at eliminating the layers of incrustations and consolidating and redefining the marble elements that have degraded over time.
The restoration, which was carried out by the San Zanobi Consortium in which a group of Florentine companies was involved, was particularly complex as the eight facades had encrustations of different nature and thickness due to the heterogeneity of the materials used and to the different exposure to atmospheric agents.
The use of laser technology has proved fundamental for the cleaning of over-damaged surfaces that would not endure traditional cleaning of chemical or mechanical nature, such as window frames.
