Difficulty’s in working with meteorite as a pamor material

BSMStar · 24th March 2006, 07:29 PM

Gee, have I been asleep at the wheel...

It is possible to determine if there is a meteoritic content with a minimally destructive test. The issue is finding an Electron Microprobe...

The surface must have a very small area polished (that is the destructiveness of the test). The Electron Microprobe will determine what elements are available. Earth surface rocks do not have the same availability of trace elements as meteorites. The trace elements are the fingerprint used to identify cosmic materials. Therefore, even if there is only one percent meteoritic material in the metal, it is still possible to tell if meteoritic material is present or not.

If there is only a small percentage of meteoritic material in a Keris, then looking at Ni content alone will not be an indicator of cosmic origin since the majority of Ni is not from the meteorite itself. Therefore, short of testing, there really is no way to know if a Keris has meteoritic material in it.

Great article Rick!

HERE ARE 3 EXAMPLES OF KNIVES WHERE THE BLADES ARE MADE FROM A SLAB OF NATURAL UNFORGED METEORITE. THEY ARE JUST SHAPED AND POLISHED MECHANICALY. TWO ARE FROM THE GIBEON METEORITE AND PART OF THE OUTER SURFACE OF THE METEORITE WAS LAFT NATURAL UNWORKED OR POLISHED. I HAVE NO IDEA HOW THIS TYPE OF BLADE WOULD HOLD UP, BRITTLE, NOT TAKEING OR HOLDING A GOOD EDGE

AT ANY RATE THIS DOES SHOW METEORITES COULD HAVE BEEN WORKED USING PRIMATIVE METHODS SO A OLD UNFORGED METEORITE BLADE IS NOT OUT OF THE QUESTION.

I JUST RAN ACROSS A CURRENT ARTICLE ON ONE OF THE DAGGERS FOUND IN KING TUTS TOMB. THEY ARE SAYING THE IRON BLADE IS LIKELY MADE FROM A IRON NICKEL METEORITE. A PICTURE OF THE DAGGER.

I was surprised that the authors of the paper seemed unaware of the use of meteoric iron in the Indonesian culture.

I don't think it is so much a matter of being unaware of meteoric use in Indonesia as much as that their focus is more on the use of that material by ancient peoples.
The remarkable thing about this dagger is that it was created at least a century before the acknowledged start of the Iron Age and many centuries before edged weapons were commonly made of iron.

Just a note: most of the "meteorite" blades claimed by dealers are not meteorite but laminated local steels.
