Those of you that remeber the LP will recall that it produces sound by the vibrations of a needle in a groove in something spinning quite fast. The same principle lay behind the old way of recording music on the wax cylinder (which even I don't remember). Now, pottery is made by spinning a lump of clay on a wheel and shaping it. In theory, ambient sounds at the time the pot was thrown should be recorded in the clay. All you need is a way of playing it back, and you might catch the tune the potter was whistling as he worked .....

In theory.
