Did anyone see that mythbusters where they thought they could record into a clay pot and play it back? I think there was a myth saying how you could (using a laser) play ancient pots from old civilizations because they inadvertently captured the conversations of the artisan while they were making the pots with a piece of straw...the straw acting as the needle and transfering the sound into clay. It ended up not working.

There's a book called Audio & Hi-Fi Handbook that spends a good hundred pages on the subject.
