Abstract: A REVIEW of the historical development of hydration-rind dating is presented.Basaltic glass has been found to hydrate at a linear rate.During glass hydration an immobile product layer is formed at the interface between reactants.The immobile product layer develops from a microfracture chemicalchannel zone.This layer converts to a band of palagonite.The rate of palagonite banding is directly related to the chemistry of the glass, the availability of water, and the temperature during hydration.Rate formulas are presented.Archaeological sites in the Hawaiian Islands provide a test of the validity of this new dating tool.Sites from two islands are discussed in relation to the correspondence of hydrationrind with C-14 dates.The immediate prospects for the use of the method and tentative conclusions are offered.
