[QUOTE="TIF, post: 2164612, member: 56859"]Here's my latest, an eBay Roman Egyptian. As with so many bronzes, this one had wax or makeup rubbed on. The "after" images are fairly accurate, maybe a bit more relief in hand. Rubbing alcohol dissolved the "sand". While I do like the contrast and enhanced details brought out but such applied patinas, concern about what the unknown material might do to the metal is reason for its removal. Given the ubiquity of such applied substances, it might be a good idea to routinely soak all of your bronze coins in rubbing alcohol, mineral spirits, and water (sequentially; some or all of these soaks depending on the coin).
