Rehydroxylation rhx dating

more 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.

In this paper, we discuss how the initial stages of mass gain are affected by the specific surface area (SSA) of the ceramic material.

This finding has led to the formulation of a new empirical equation, which describes the observed ceramic's rehydration and RHX behavior without the need for identification of RHX stage.

As part of this study, the mineralogy of the ceramics and their thermal properties have been evaluated.

The paper provides guidance on experimental protocols to avoid dating results being distorted by relatively early-time mass gain data.

Rehydroxylation (RHX) dating has recently been proposed as a new chronometric dating tool for use on archeological fired-clay ceramics.

Excavated materials prove difficult to date because of the different thermal environments of different loci.Since its introduction in 2009, application of the rehydroxylation (RHX) technique for dating fired-clay ceramics has been controversial, with very few satisfactory dating results collected in the interim. more Since its introduction in 2009, application of the rehydroxylation (RHX) technique for dating fired-clay ceramics has been controversial, with very few satisfactory dating results collected in the interim.The stability and efficiency of this technique has been called into question by several investigators in the last few years, who have struggled to reproduce and validate this new dating method. 2000–7000 yrs old ceramic artifacts, the reproducibility in the RHX process rate is analyzed and discussed.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.In this paper, we discuss how the initial stages of mass gain are...
