It is based on the fact that after a ceramic specimen is removed from the kiln at the time of production, it immediately begins to recombine chemically with moisture from the environment. This reaction reincorporates hydroxyl (OH) groups into the ceramic material, and is described as rehydroxylation (RHX). The RHX process produces an increase in specimen weight. This weight increase provides an accurate measure of the extent of rehydroxylation. The dating clock is provided by the experimental finding that the RHX reaction follows a precise kinetic law: the weight gain increases as the fourth root of the time which has elapsed since firing. This so-called power law and the RHX method which follows from it were discovered by scientists from the University of Manchester and the University of Edinburgh.The concept of RHX dating was first stated in 2003 by Wilson and collaborators who noted that "results ... suggest a new method for archaeological dating of ceramics". The RHX method was then described in detail in 2009 for brick and tile materials, and in relation to pottery in 2011.RHX dating is not yet routinely or commercially available. It is the subject of a number of research and validation studies in several countries."@en }
