Archaeologists typically use a high-precision microscope or a scanning electron microscope to view the thin section of the sample. As laboratory protocols become more standardized, the reliability of obsidian hydration as a scientific tool continues to grow.
Microscopy In Obsidian Hydration Measurement: Precision And Process
Because of this variability, researchers must calibrate their formulas using regional data. Furthermore, if an object was reheated after its initial creation, the hydration clock resets, as the heat releases the accumulated water.
Technicians measure the depth of this translucent layer, which is usually expressed in micrometers, to feed into the dating equation. Contributions to Archaeological Research Obsidian hydration has fundamentally changed how archaeologists understand the movement and trade of ancient peoples.
Microscopy Techniques in Obsidian Hydration Measurement
When obsidian is fractured and exposed to the elements, ambient humidity begins to permeate the microscopic surface imperfections. Because obsidian sources are chemically distinct, hydration dating not only tells us when an item was made but also helps trace its raw material origin.
