Moisture expansion and mass gain in fired clay ceramics: a two-stage (time)1/4 process
The phenomenon of reversible moisture expansion in brick has been recognised for nearly 100 years. This formed the basis of the initial RHX dating method. However, it was found that micro-cracking following heating at 500C was contaminating measurement as moisture expansion was occurring. The approach was completely shifted to the measurement of mass gain rather than expansion by moisture adsorption. This represented a paradigm shift in the accepted methodology of the last 100 years. The results in terms of brick dating were highly successful and this approach is now followed by all researchers in this newly-emerging field.
