The location of the section is determined by the morphology and the perceived potential of the location to yield information on the manufacture, use, and discard of the artifact.

The specimen is then inverted and ground to a final thickness of 30-50 microns, removing nicks from the other side of the specimen.

Where In the World Does Obsidian Hydration Dating Work?

The hydration rate is typically established empirically through the calibration of measured samples recovered in association with materials whose cultural age is known or whose age can be radiometrically determined, usually through radiocarbon dating methods (Meighan 1976).

The hydration rate can also be determined experimentally, an approach that has shown increasing promise in recent years (Friedman and Trembour 1983; Michels et al. An appropriate section of each artifact is selected for hydration slide preparation.
