[meteorite-list] Fukang preparation extraneous material

[Matt Morgan]

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.
