Results demonstrate that in the majority of samples, complete dehydroxylation (DHX) did not occur within, or even beyond, the conditions common in traditional firings.
Consequently, between 0.01 and 1.5% of a sample's mass in residual OH may remain after firings analogous to those observed in the ethnographic record.
TY - JOURT1 - Are the intensities and durations of small-scale pottery firings sufficient to completely dehydroxylate clays?
Thus, in many cases, a key assumption underlying current RHX dating methods is unlikely to have been met, introducing considerable error in dates.
But did it really happen as the Bible describes it?
Continue reading The story of the Israelite conquest of Jericho (Joshua 2-6) is one of the best known and best loved in the entire Bible.
As soon as a clay pot is removed from the kiln, it begins reabsorbing hydroxyl ions, found in water, at a very reliably-measurable rate.
Since each pot is made of a unique mixture of clays, it reabsorbs these ions at a unique rate.
