A New Way to Date Old Ceramics. January 10, 2011— If you are an archaeologist, determining when a pot was made is not just a matter of checking the bottom for a time stamp.
Dating clay-based materials like ceramics recovered from archeological sites can be time consuming, not to mention complex and expensive. Patrick Bowen, a senior majoring in materials science and engineering at Michigan Technological University, is refining a new way of dating ceramic artifacts that could one day shave thousands of dollars off the cost of doing archaeological research.
Called rehydroxylation dating, the technique was recently developed by researchers at the University of Manchester and the University of Edinburgh. It takes advantage of ceramics’ predictable tendency to bond chemically with water over time. “It’s simple,” says Bowen. Then, weigh the sample and put it in a furnace at 600 degrees Celsius. Then weigh the sample again and leave it alone.
Bowen’s equation worked better, but not well enough to generate definitive dates. Archéologie - Science - Actualité.

The fieldwork involves the recording of rock art within an 850 m stretch of the valley, at a point where the Ocreza flows into the Tagus River. In the recent past, both rivers have been subjected to water levels dictated by the various dams that interfere with seasonal river flow. The team directors, who organise each year a field school devoted to rock art, have since 2011 been recording six panels. 12 April 2014 Vandals damage rock art in Northumberland Vandals carved into the historic rock art at Lordenshaw in Rothbury, Northumberland (England).
