Hello Andi, Mike and List,
Those interested in an iron that will be extremely difficult to
classify
had better hurry because Andi is almost sold out. I am pleased I will
soon own #17 and I've been brooding tonight over Andi's pics and Ted
Bunch's preliminary description of that one-of-a-kind iron, its carbon
rosettes, its granular kamacite, its iron, nickel, cobalt,
phosphorus and
Si contents.
I went through numerous Vagn Buchwald pages reading about and
looking at
several pics of IIF irons trying to figure out what this new iron
might be.
I re-read information about La Caille, but, ... nothing comes
really close
to what this weird iron looks like. Can hardly wait to look at it
under my
microscope and am eagerly waiting for final classification results
from
Ted Bunch and other labs!
This iron is so weird that even Ted Bunch is not sure yet whether
it should
be classified as a IAB, a IIF or a IIICD iron!
Best wishes,
Bernd
I too bought one of Andi's slices. Slice #13.
I read Ted Bunch's preliminary analysis and it seemed like the Co
content was way too low to be a member of the IAB group. In fact in
seemed low period.
I wish I had Metbase handy so I could make more comparisons. Any
else have an opinion about the Co content?
