Before and After - Acetone use
STONE
Posts: 15,275 ✭
A big thanks to Arizonadesertrat for taking the time to show me and perform the processes of carefully removing unsightly gunk on the surface of this coin with the aid of acetone.
These two images were shot at different times and using slightly different lighting, so they aren't quite a match.
On the before image there still was a slightly hazy green film on the surface, which has now almost all but been removed through Acetone.
Also you will notice the disappearance of the mystery yellow substance and the major pockets of green have also dissolved away.
You should be able to assess the large improvement acetone has played in conserving this piece below.
(This coin probably still needs another long soak to remove the tiny little fragments of green in the smaller sections of said coin.)

Looking good.
Will you soak it further?
edited to add that I think your coin looks a lot better after the dip.
What about copper?
I thought it was OK too, but the few times I used Acetone as a dip to get rid of PVC the color changed.
Actually I like the 'tone' of these pieces, but don't want to be considered a Ph.D.!

<< <i>same lighting? >>
A slightly different lightbulb was used in the first image.
The second image was used with a 100 Watt Reveal Bulb, while the first used a 60 Watt Ultra Soft White.
<< <i>Will you soak it further >>
Probably. It's very good right now, but if it's possible to remove more, then I will be much more satisfied with the extra removal.
<< <i>I always give every silver coin I buy that is raw a quick soak and have never had any problems.

He said silver, not copper. In fact, I think many folks advise against using acetone on copper. At least I never use it on copper anyway.
Although it is recommended to use caution when handling acetone (protect your skin and eyes, as well as stay clear of open flames), the results are quite apparent.
