Rehydroxylation dating of fired clays: an improved time-offset model to account for the effect of cooling on post-reheating mass gain

Evidence for Complexities in the RHX Dating Method

“…It is worth mentioning that the observed concavity and convexity in mass evolution do not coincide in time with perturbations in the environmental conditions in our climatic chamber. Therefore, contrary to the data reported in Barrett () (we note, using larger cubic samples than ours, with 25 mm sides) and Wilson et al . (), these two behaviours most probably result from intrinsic properties of the studied samples, rather than from particular disturbances in the environmental conditions at the beginning of the experiments (see Wilson et al .…”

Composition, Microstructure and RHX Dating of Romanesque Relief Ceramic Tiles

“…This method was proposed as self-calibrating without any standardisation and, thus, neglects the influence of firing temperature or mineralogical composition as demonstrated in Wilson et al [23]. The futher testing of this method on real samples showed the need for further investigation, especially in connection with the mineralogical composition and storage conditions [24][25][26][27][28][29][30].…”

Reproducibility in Rehydroxylation of Ceramic Artifacts

“…Because no other research team was able to successfully date ceramic artifacts through the protocols proposed by Wilson et al., the RHX dating method remains controversial. Only poorly reproducible results were reported so far, with many requiring variations on the original ¼ power law. In our previous contributions, we have used a generalized power law ( 1/n ) with a variable exponent ( n ), to describe the RHX behavior of ceramics without identifying their ages .…”
