The process of dating ancient obsidian artifacts converts the quantity of surface diffused molecular water to a calendar age using an experimentally derived diffusion coefficient predicted from glass composition. The internal structural water content

Laboratory hydration of obsidian is based on the principle that the measurement of water penetration at high temperatures allows computation of hydration rates at archaeological temperatures. Accuracy of the laboratory hydration method is sensitive t

Water diffusion in high silica volcanic melts results in the formation of rhyolite glasses where hydroxyls are linked to the silica tetrahedra. Space between these linkages form pathways for the diffusion of molecular water into the glass surface dur

The obsidian hydration dating method requires a measurement of the amount of diffused water (%H 2 O D ) within the surface hydration layer and an assessment of the structural water (%OH) contained within the underlying glass matrix. Infrared photoaco

The induced hydration method is based on temperature scaling; obsidian samples are hydrated in the laboratory at elevated temperatures, and hydration rims are then measured. The activation energy and diffusion constant are determined analytically, an

Hydration rate development on obsidians within the laboratory has become the preferred calibration procedure for the obsidian dating method. A fundamental assumption of this calibration procedure has been that water concentration within the hydration
