A new way of dating archaeological objects has been found, using water to unlock their "internal clocks".
Fired clay ceramics start to react chemically with atmospheric moisture as soon as they are removed from the kiln. Researchers believe they can pinpoint the precise age of materials like brick, tile and pottery by calculating how much its weight has changed.
The sample is then weighed in a "super-accurate" device, known as a microbalance, to determine the precise rate at which the material will combine with water over time. Source
