An effective lifetime temperature (ELT) is defined, and we show how this is related to the temperature history of a sample.
The ELT is used to adjust the RHX rate constant obtained at the measurement temperature to the effective lifetime value used in the RHX age calculation.
The RHX process produces an increase in specimen weight.
This weight increase provides an accurate measure of the extent of rehydroxylation.
You can do this with thermoluminesence, which uses natural radioactivity to give a date, but it’s complex and difficult so it’s rarely used.
TY - JOURT1 - Rehydroxylation (RHX) dating of archaeological pottery AU - Wilson, Moira A.
more Rehydroxylation is a developing method of dating fired materials that was introduced to fired brick in 2009 and archaeological pottery in 2012.
This technique is based upon dating the Stage II kinetics of the rehydroxylation process using a (time)1/4 power model.
is a good weasel word, but if Rehydroxylation Dating can be independently verified then it could be a more important form of dating than radiocarbon dating.The reason it’s so exciting is that this method will allow archaeologists to date pottery. I am not a materials scientist so it’s possible that if something seems odd that’s me messing up the description. Pottery and other ceramics make up most of the data that you’ll find on an archaeological site.The other is I am not on the research team — I’ve merely emailed some questions. Unfortunately there hasn’t been an easy way to directly date it. Pot types and technology come into and out of fashion.AU - Hamilton, Andrea AU - Ince, Ceren AU - Carter, Margaret A.AU - Hall, Christopher PY - 2012/11/8Y1 - 2012/11/8N2 - We show that the rehydroxylation (RHX) method can be used to date archaeological pottery, and give the first RHX dates for three disparate items of excavated material.
