Furthermore, if an object was reheated after its initial creation, the hydration clock resets, as the heat releases the accumulated water. When obsidian is fractured and exposed to the elements, ambient humidity begins to permeate the microscopic surface imperfections.
Methods for Measuring Hydration Rind Depth and Refining Age Estimates
These advancements have refined the diffusion models, making it possible to generate age ranges with tighter confidence intervals. One of the most nuanced aspects of obsidian hydration is accounting for the environment in which the artifact rested.
The process involves polishing the artifact to a specific standard and then applying a chemical etch to make the hydration rind visible under magnification. The thickness of this rind is the primary data point measured in laboratory analysis, as it correlates directly with the age of the artifact under stable environmental conditions.
Methods for Measuring Hydration Rind Depth in Obsidian Artifacts
As laboratory protocols become more standardized, the reliability of obsidian hydration as a scientific tool continues to grow. Archaeologists must also consider the potential for surface contamination or chemical alteration that could skew the hydration measurement.
