Extremely Fine Nero As; High End Clean


Not all cleans are cheap 4th century slugs. Below is a risky, but high reward clean (if you are experienced enough to pull it off).

Until you have had years of practice, taking a scalpel to an extremely fine Nero As is not recommended.


From the before photo, you can see it’s encrusted with a thin layer of dirt that will require a steady hand to remove.

The patina below is stunning and has strong potential. The patina is thick, which also means forgiving during a clean. That being said, the slightest wrong move means permanent damage, which on such a high end piece is catastrophic.
