Abstract

The reconstruction of time is a central concern all archaeologists must address in their research; few, however, are fully aware of the potential of all the dating methods at their disposal. For this reason, this paper summarizes the developmental history and current level of field application of obsidian-hydration dating. It (1) reviews how this dating technique was first discovered and applied, (2) details our current knowledge of the process of hydration and which variables affect its rate, (3) discusses the relative advantages and limitations of the three primary approaches employed to construct hydration chronologies, and (4) presents a protocol for its future application in Mesoamerica. The synthesis of this body of hydration-dating research may help archaeologists more constructively decide how and when to apply this unique and versatile dating technique to their specific research questions by providing the information and guidelines necessary for recovering pertinent field data.
