Rehydroxylation dating

This technique is based upon dating the Stage II kinetics of the rehydroxylation process using...more Rehydroxylation is a developing method of dating fired materials that was introduced to fired brick in 2009 and archaeological pottery in 2012.

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.Mineral alteration during reheating is generally negligible except when gypsum is present; large sources of uncertainty arising from moisture loss associated with dehydration and with subsequently lower levels of physisorption following reheating are highlighted as problematic.Rehydroxylation (RHX) dating was recently suggested as a simple, cheap, and accurate method for dating ceramics.As part of rehydroxylation (RHX) dating trials on post-medieval bricks, investigations were carried out into the presence, and effect on age estimations, of uncertainties associated with (a) prolonged and incomplete drying of samples, (b) the removal of organic and non-organic matter during heating, and (c) mineral alteration during heating.All samples exhibit an issue with a prolonged period of drying, exceeding two months at 130 °C.
