I took these
coins out 2 days ago, just haven't felt too well, so didn't post them until
now. They weigh 32.0g, so yet another 0.2g was removed. The two As's and
the Centionalis has lost 99% of the dirt. The FH Cent seems to be a very
worn coin. The Moneyer As still has a bit of encrustation that I will have
to work on. I don't blame the bare metal showing on my process... I believe
it wasn't patina'ed to begin with, but was covered with the encrustation.The
Claudius is still a bit rough. I can't decide if the majority of the green
is patina or encrustation, but nevertheless, I will work on smoothing it
out.The muddy coin in the above scan (bottom row) seems to have formed a
patina over the mud. It takes some work, but I can scratch through it to
reveal dirt (you can see the lighter patch on the reverse of the coin).
It took me 2 minutes with the DDDP just to remove that much, so soaking
alone isn't going to remove that. The oblong coin in the middle row, far
right, in the above scan has lost 90% of the dirt. It has revealed a light,
scattered encrustation that I will have to work on manually. The coin in
the middle is starting to reveal details. It has a blackish finish to it
that reminds me of tar, but I'd say 75% of the dirt has been removed. Next
to that, the Vot coin (middle row, left) has lost maybe 60% of the
dirt. It is still encrusted with this odd black coarse material, so it will
most likely have to be operated on manually as well.
I don't think any process is going to eliminate the need for scrubbing with
a toothbrush occasionally nor some gentle sanding/picking with a DDDP or
equivalent. That being said, I have to label this as yet another success.
Much faster and more thorough results compared to conventional soaking. |
