Rehydroxylation rhx dating
If a sample was not completely dehydroxylated during its production, then current RHX methods would systematically overestimate its age.Results demonstrate that in the majority of samples, complete dehydroxylation (DHX) did not occur within, or even beyond, the conditions common in traditional firings.To obtain accurate results in the RHX dating of ceramics, it is essential that the RHX measurements are continued until the rate of mass gain is constant with (time)1/4.
Some scholars have noticed flaws in this original formula and therefore this experiment will test an amalgamation of their proposed alternative models.Timespan analysis was performed, and age uncertainty related to RHX dating technique was evaluated by considering the error propagation.The results show poor reproducibility of the RHX process in the samples of the same origins, which give new evidence for a revision of the RHX protocols.
