[meteorite-list] Suspected Meteorite Being Sent for Test inBangladesh

[Sterling K. Webb]

Hi,

    A touchstone is a piece of slate, fine-grained,
used to "test" the purity of purported gold in
ancient times, up to the XIXth century when
chemical tests began.

    See:
http://www.pamp.ch/gold_c/Info_site/in_glos/in_glos_touchstone.html

    Google, always Google!

    Presumably, the rock was heavy in density,
dark in colour, and without obvious texture or
inclusions.

Okay, is this some sort of translation problem?  What is a "costly live
touchstone"?
