:

If so, call the chemistry department and ask
who teaches the undergraduate instrumental analysis course and when
they have their office hours and pay them a visit with a sample they
can use in the course as an unknown, along with an appropriate
beverage :-).

Good idea! No, the scrapyard is not one of that sort (ultra-redneck-
true-'junkyard' sort of business).

But I have a college with a good materials sciences department just 25
miles away.
