Rehydroxylation dating sample
The RHX process is the chemical absorption of atmospheric water by fired clay ceramic that proceeds by very slow nanoscale solid-state transport or single file diffusion into the clay body.
This resulted in the discovery of a new kinetic law that the extremely slow reaction kinetics of moisture expansion follow a time, etc.) units of time whether these units are seconds, minutes, days or years.
more Rehydroxylation is a developing method of dating fired materials that was introduced to fired brick in 2009 and archaeological pottery in 2012.
The rehydroxylation process is a chemical reaction and is based on temperature.
It has been shown that estimation of an “effective lifetime temperature” (ELT) for the location where the sample was obtained, provides a reliable temperature under which to perform the analysis to approximate the conditions seen by the sample during its lifetime.
Different levels of humidity have had a significant effect on mass gain, contrary to previous literature.
Introduction RHX Dating Methodology Procedure for RHX Data Conclusions About Quantachrome Instruments The rehydroxylation (RHX) dating technique is a completely unexpected result of a study of the reversibility of moisture expansion in fired clay brick.
