Hi List....regarding re-etch work, I again nominate Mike Miller. I've sent
some critical specimens to him and his work (as we know) is tops.

Hi Gary, What a great example you are and welcome back, you're a great
fighter and I hope you're kicking butt!
Jim's is one point of view and I understand most do something like that.
But keep in mind that absolutely nothing beat a re-etch. If the meteorite
has oxidized somewhat, you will have on a microscopic level pitting that
is catalytic to more oxidation and you no longer have a good surface -
it's gone like a pristine magnetic recording on a warped record.
I feel the better answer is not to try top cut corners by loading more
foreign chemicals. Why not just buff and polish it, rinse/dry a few
cycles in distilled water, and buy some nitric acid and etch it yourself.
Really, when it comes to work, The FRAM man has the answer:
"You can pay me (a little) now, or pay me (a lot) later".
And I know you're not afraid to roll up your sleeves!

Hi Gary,
I use a product called "Bar Keepers Friend" to freshen up my etched
irons.
It comes in a powder and liquid form. Get the powder one. You can find it
in the cleanser isle of most grocery stores or Walmart. Wet the etched
surface with warm water then mix the Bar Keepers Friend into a paste,
then
gently apply it to your etched surface. I use my finger to rub it gently
for
about 2 minutes. Then rinse with water, then soak in alcohol, then dry in
an
oven, then soak in ATF (Automatic Transmission Fluid), wipe dry and your
good to go.
Cheers,
Jim K

Though I've been away for some time in recuperation I am still alive and
kicking and VERY grateful for this list's members for their help in my
hard times a few years ago. Getting well enough now to get back to my
collection and noticed a Gibeon slice has oxidized enough so the etchings
have severely faded. Anyone know how to restore the etchings without
re-etching?
Also, I noticed a new trend in selling mets on eBay. Most are selling
for
Buy Now or Best Offer. What's up with the market?
