Ancient craft yields storage medium of the future

The preservation of our collective story — so much of which is told in electronic pulses and stored in bits and bytes — may well hinge on the oldest of materials: clay.

It’s not just any clay. It’s a specially designed stoneware (the stuff of bathroom tiles) formed into 20-by-20 centimeter ceramic tablets. Martin Kunze, an Austrian ceramist and researcher, invented them, and once printed with snippets of science, politics, art, culture and much more, he stores them in a cavern in a salt mine in Hallstatt, deep in the Austrian Alps. The cavern, accessible via an 80 centimeter-wide tunnel, will naturally close up over time. There, what Kunze calls “the greatest time capsule ever” will wait for someone, someday, to find it.
