Rehydroxylation dating research

Trevor Foster AZo Network speaks to Trevor Foster on the expanding roles of ultrasonic flowmeters.Trevor draws upon over 40 years of using innovative design and production techniques to produce elegant flow metering solutions for organisations around the globe. Mike Keeble Aerospace is a demanding industry for new product development and quality control. Mike Keeble from Buehler about how they are rising to the materials testing challenges set by the Aerospace Industry.The Cellite™ series of Sandwich Panels have been used for a number of years to design bonded assemblies, composite components, and lightweight structures for the defense, aerospace, marine, motorsports and rail industries.The Total Tank Level System (TLS) from Drexelbrook is the cutting edge in magnetostrictive probe design.This allows peerless accuracy for tank level measurement as well as multi-variable functionality (total level, interface level, volume and temperature).The simple method promises to be as significant a technique for dating ceramic materials as radiocarbon dating has become for organic materials such as bone or wood.

) of the sample due to rehydroxylation over the life of the sample is proportional to time to the ¼ power and is given by Equation 1 Figure 3. Only the section of the data highlighted red is used to calculate the RHX rate constant (Stage II).

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.

Before that the observed mass gain is due to several processes occurring simultaneously (Stage I). The proportionality constant a T is the slope of the linear portion of the mass vs.
