It sure would, Eric.
I should point out though, that there is a PowerPoint presentation available
on the subject under the downloads category on the IMCA site. It is entitled
Meteorites 301, and is a follow-up to 201 and 101, as you would expect. I
just downloaded them all last week, and may use the first two for a upcoming
Boy Scout presentation.
I should also point out that I have not *yet* done any etching, so the
contents of this PowerPoint program pretty much match the extent of my
knowledge on the subject! ;^)

Hi McCartney, Ron, Listees,
This might actually be a good topic for an article on the new Meteorite
Wiki. Perhaps an experienced and generous person would be willing to
extend the time to write an extensive and detailed article on it including
information on preservation and stabilization. I'm sure others would love
to learn the process. I would be will to add a few of my photos to the
document and release them into the public domain for all use. What do you
think?

Hello McCartney (and all):
Yes, the etch happens very quickly and you need to terminate it by a
quick wash under running water. Follow with a rinse in distilled water
if you want to but we never do and it works fine. You don;t have to
neutralize it, just wash it off VERY FAST. In fact, I use running water
to slow down the process as I am doing it, especially if I need to etch
one section of a surface more. There is a bit of a technique - just
practice and you will do well. If yo are getting staining your washing
is incomplete.

Subject: [meteorite-list] Issue with etching via ferric choride
Having a bit of a problem on some etch jobs and having to re-etch a few
specimens.
How do you rinse/neutralize your ferric after the etch? I'm getting
remnant staining and sometimes corrosion. I'm doing something wrong.
Any ideas?
