Hi List.
Tooday Im your main spammer here :)
Jeff have some problems so I forvarding his email.

List -
Speaking from experience in backyard steel foundry work, the etched slices
clearly indicate to me that the shirokovski was made in a direct attempt
to
defraud meteorite collectors - it does not appear to be a serendipitous
furnace lining pallasite look-alike.
Next time I fire up the blast furnace, I'll check into it and give you all
a
report, as to whether my theory is correct or not.
Wustite and fayalite are common iron/steel slag components, as is CaO.
Off hand, the hard part would probably be keeping bubbles out of the melt
upon introduction of the silicates - it possibly required a vacuum
furnace,
or at least careful timing (accidental?) of the introduction of the
olivine
and solid metal into the melt
