We applied the rehydroxylation method on precisely dated French archeological fragments.

This continues over its lifetime causing it to increase in weight – the older the material, the greater the weight gain.

High quality planar waveguide YAG/Nd: YAG/YAG ceramics were developed by Prof.

LI Jiang's group at Shanghai Institute of Ceramics of Chinese Academy of Sciences and were tested as laser gain media by the research group led by Prof. Holography technology provides a promising way to design and reconstruct electromagnetic waves with desired phases and amplitudes, which has a broad range of applications in beam shaping, in authentication, and in the entertainment industry.

First, based on the published protocol, the “archeological mass” of a sample should be determined following an initial drying at 105 °C when the slope of the mass over time is zero.

In all our experiments on ∼60 samples, no stabilization of the sample mass is reached even after several weeks of monitoring.

(BCS-0714727), was aimed at improving interpretations of grinding tool assemblages related to pre-contact hunter-gatherer societies.

Grinding experiments were organized as a collaborative learning experience for middle-school and high-school students and formal and informal educators.

A team from The University of Manchester and The University of Edinburgh has discovered a new technique which they call ‘rehydroxylation dating’ that can be used on fired clay ceramics like bricks, tile and pottery.

Working with The Museum of London, the team has been able to date brick samples from Roman, medieval and modern periods with remarkable accuracy.

We show that the rehydroxylation (RHX) method can be used to date archaeological pottery, and give the first RHX dates for three disparate items of excavated material.

The experiments engaged the students and educators in the scientific process of gathering data and developing and testing hypotheses, thereby enhancing science education.
