Sistine Chapel Fresco Gets a Salt Facial
28 Feb
Summary
- Restorers are removing a chalky salt film from Michelangelo's fresco.
- The cleaning operation is expected to conclude by Easter.
- Climate change and visitor humidity contribute to salt buildup.
Michelangelo's iconic fresco, "The Last Judgement," is currently receiving a specialized cleaning to remove a pervasive salt buildup. This chalky film has accumulated on the Renaissance masterpiece since its last major renovation approximately three decades ago. The process involves applying sheets of distilled water-soaked Japanese rice paper to gently lift the salt.
The Vatican anticipates the cleaning operation will be completed by Easter, which falls in the first week of April. While visitors can still access the chapel, a reproduction of the fresco is displayed over the scaffolding. Experts attribute the salt accumulation to increased humidity from the nearly 25,000 daily visitors, noting that higher temperatures due to climate change exacerbate the issue.
This unique maintenance is necessary because the fresco's location behind the altar prevents the use of standard nightly cleaning equipment. The Sistine Chapel itself underwent a comprehensive restoration from 1979 to 1999. The Vatican is now exploring technological solutions to manage humidity levels and prevent future salt formation on this invaluable artwork.
