Gessificazione di Venezia
In queste pagine è documentato lo stato dei mattoni, della pietra d'Istria, dei marmi di Verona, e più in generale dei calcari a Venezia. Come si può vedere l'aggressione sulfurea stà divorando le pietre con una velocità che non consente più esitazioni. |
Venice becomes chalk
In these pages we document the state of the stonework - bricks, Istria stone, Verona marble, and generally all of the calcars - of Venice. As will be seen, the assault of sulphur is consuming stones at a rate that allows us no more time for hesitation and speculation as to the effect on the fabric of the city. It is happening before our eyes.
Most of the damage is very recent. Sulphur concentration in the air has reached a critical point. Calcitic crystalline inclusions, deep inside the stones, have been substantially dissolved, resulting in the structure of the stones breaking down. One major example is the capitals of St.Mark's Basilica, and most other Istrian stones around Venice are in as bad a state. At this rate of corrosion, within ten years most of the decoration and pierced marble fretwork and arches of the town will be erased, and the structural stones will be unable to support the weight of the buildings! The columns of Rosario's church on the Zattere (Gesuati) have already broken through their plinths! |
