In the context of this artwork, explain the Restoration of the The bronze David.
The statue underwent restoration from June 2007 to November 2008.  This was the first time the statue had ever been restored, but concerns about layers of "mineralised waxings" on the surface of the bronze led to the 18-month intervention. The statue was scraped with scalpels (on the non-gilded areas) and lasered (on the gilded areas) to remove surface build-up.
