Ancientnoob Pillar of the Community United States 5155 Posts	Posted 03/06/2015 11:15 am I was toying with the idea of tackling the encrustation on this Alexandria tetradrachm to release the face of the emperor and clear the right obverse field. The encrustation remains impervious to all of my soft tools. Before After Report this Post to the Staff

Ancientnoob Pillar of the Community United States 5155 Posts	Posted 03/06/2015 11:19 am Under magnification the encrustation seemed to be resting on top of the surface rather then being a product of corrosion. I hit it with the new Dremel Micro 15000 RPM with a fine tipped steel tool with a small ball on the tip. Broke up the encrustation without harming the surface a pinch. This took about an hour and a half. I also took a sample of the encrustation to attempt to dissolve in different solvents. (For experimentation sake) Report this Post to the Staff

Ancientnoob Pillar of the Community United States 5155 Posts	Posted 03/06/2015 2:35 pm Thanks all. I found it difficult to fight the urge to re draw the details. Comfort leads to complacency and that leads to a ruined coin. I noticed I was having good progress, and decided to take a step back before proceeding further. It was recommended that a Dremel bit # 536 would do a nice finish job at 5000 RPM. Eddop- Nice to see you. Thanks for the attribution and quite a lovely example. This guy is had a relatively short reign and sacked Ctesiphon under Varhran II of Persia. Neat! Edited by Ancientnoob 03/06/2015 2:37 pm Report this Post to the Staff
