Hi Adam and List,

If you could melt down and recycle an old Ford engine block into
something that looked close enough to a pallasite to fool many people,
then it would be worth money to some collectors. Heck, it would fetch
a premium because *you* made it in an overt attempt to show up
Shirokovsky and make a pseudo-pallasite. We could call it "Hupilac
Pallasite" ;)

Seriously though, Adam's strong negative reaction to Shirokovsky is
proof positive of two things - it evokes a passionate response in the
meteorite collector community (from a veteran respected member no
less), and that makes it collectible to some people. Like it or not,
Shirokovsky has become an infamous member of the meteorite community -
lovely horrid phoney thing that it is. It might be made from 3 parts
Russian beer cans and 1 part yellow ale, but when sliced and polished
properly, it can be quite beautiful in it's own fraudulent way. That
is why so many people spent good money on it when it was first
misrepresented as a meteorite. If it was absolutely terrible to look
at, from an aesthetic standpoint, very few people would have bought it
and would probably wouldn't be talking about it now.

The problem with Shiro is not it's fake nature, it is how/why it was
represented as a meteorite. I do not know the entire back story yet,
but the material was knowingly offered as a meteorite by
sellers/finders who knew (or strongly suspected) it was not a real
meteorite. They lied about tests being done and the nature/results of
those tests. It scammed a lot of people who thought they bought a new
pallasite and instead owned a piece of smelted engine block with
olivine windows. Had Shiro had been an accidental slag creation (like
Mendota probably is), then it would not have such a negative
connotation. What many people find objectionable about Shiro is not
the material itself, so much as the way it ripped people off through
fraudulent misrepresentation.

To me, it is an interesting meteorwrong and it sits in a cabinet
drawer I have dedicated to meteorwrongs - there are all clearly
labeled as such. They are used for comparison purposes to trying to
explain meteorite identification to others and for my own personal
enjoyment for compiling many types of wrongs.

I will freely admit - if I had been duped and got ripped off on a
Shiro specimen while thinking it was a real meteorite, I would have a
sour taste for it and I would rather toss it into a deep lake. So I
understand the other point of view. But I am curious what the recipe
is for Shiro, how exactly it was made, and the nefarious story of
shady characters that led to it's emergence as a new "pallasite".

Best regards,

MikeG
