[meteorite-list] Polished Butts - Toliet humor aside, what exactly are they?

[Michael Gilmer]

Hi Folks,

I have seen several references to "polished butts" in the Met
Bulletin.  For example, from this recent entry (NWA 6580) approved
yesterday -

"Type specimens available at Cascadia include 1 piece originally 20.0
g, from which one polished thin section and one polished butt were
made. Thompson holds the main mass."

I did the usual Google Search ("polished butt") to find out what this
was, and you don't want to know what the results of that search were.
Let's just say, that is has nothing to do with meteorites or thin
sections.

So I have to ask the List - what is a polished butt?

Best regards,

MikeG
