The idea of obsidian hydration dating was first published by Friedmen and Smith in the year 1960.   Obsidian hydration dating is taking the hydration rim on a piece of obsidian and seeing how thick it is and then using that to put the order of events into place.   This creates a lot of very complicated issues.   Like the different types of obsidian and if they were exposed to the same amount of water.   Scientist have been trying to perfect this study for many years.   Both in the laboratory and in the field.
