Hi Rob and List,

According to Bob Haag's Field Guide of Meteorites, 12th Anniversary Edition,
1997 [Thanks Roman Jurasik!], Bob cut his Pena Blanca Springs, Texas
(Ca-poor aubrite) with "...kerosene as a lubricant, in order to preserve the
rare, water-soluble minerals inside" (Pg. 27, #69).

Yes, there is a question of damage as well as how do you now clean the
meteorite of the kerosene?

Hi All,

I did a little poking around on line and I was surprised by the variety
of denaturing agents that are used to render ethanol undrinkable.
Perhaps someone with more chemistry knowledge can assess how
bad any of the following might be to meteorites:

1. methanol (as Rosie pointed out) -- shouldn't be too bad, given that it's
just wood alcohol.
2. ethyl acetate
3. kerosene
4. gasoline
5. benzene
6. methyl isobutyl ketone
7. acetone
8. diethyl phthalate
9. crotonaldehyde
10. brucine sulfate

There are others, but these are the most common ones. --Rob
