Adam and List,
(Sometimes garbage tells a good story...just ask the identity thieves.) In
my case, I have a couple of Shiro pieces (bought as advertized as
meteor-wrong) for the sole purpose of shoe-and-tell (pun intended) and
educational purposes. Same with Putorano and Mendota...remember when Puto
arrived on the scene (can I really write it that way, again pun intended?)

This is, of course, to accentuate the true rarities and authentics of all
the real ones.

-Richard Montgomery

Let me simplify the formula a little bit:

1970's era Junkyard Ford Fairlane FE 390 Big Block + Olivine + Fraudsters +
High School Metal Shop = Shirokovsky

Here is the big block link in case you want to get your hands on your own
nickel-rich ataxite engine:

Sorry, couldn't help myself. I can't believe all of the talk over this
garbage,

Adam

Hi Bob and list

The analyses:
Metallic powder, olivine etc...
Iron: 78% Nickel:18.25%
A general structure close to a pallasite

The metallic powder structure shows that sintering was used (frittage)
The powder was produced by atomization under gas.

It is a manufactured "stone".
So they decided to reproduce that "stone".
They got something close to the Shirokovsky but didn't go further
because of the money needed etc..

Their conclusion:
manufactured product, mainly with metallic powder and sintering process

All the best
Michael B.

Hi everyone,
I received this from a list member on Shirokovsky's origin. It's a
French paper from 2005. Would anyone care to translate some of the key
points?
Thanks,
Bob
