[meteorite-list] Fukang preparation extraneous material

[doctor death]

I've recenly bought a 14 gram  Fukang on ebay. While it wasn't apparrent in 
the photos, when I received it I noticed on one edge of the slice a  yellow 
crystal fragment  seemed floating separated a few mm by a clear matrix . I 
suspect that this was material used to stablitize this pallasite in 
preparation, although it looks more like glass than epoxy. Could this 
posibly be melt, or were most of these slices being prepared using some 
hardener to aid cutting.

Howard:
I have seen this in a few pallasites recently and it is can be 
unsightly.  It is a resin that is used to keep the thin slices from 
falling apart.  Also, I had some Seymchan recently cut (by a very 
well-known person) and noticed he used some lacquer to hold together the 
crusted surface of the piece where the olivine would come off.  I 
thought it was pretty ugly and removed the lacquer.  Would rather have a 
missing crystal than a blob of lacquer! Yuck.

[meteorite-list] Fukang preparation extraneous material

[bernd . pauli]

Hello Howard, Matt, and List,

I thought it was pretty ugly and removed the lacquer

Another unpleasant side effect is there are hundreds of air bubbles when I
look at my Fukang slice under the microscope. There are so many bubbles that
it isn't much use taking pictures under the scope - bubbles is all you see :-(

Cheers and let's keep our fingers
crossed for Walter and Iris !!!

Bernd
