Obsidian Hydration Dating
A simple optical method is described that will enhance the color contrast between the outer birefringent hydration rind and the inner unhydrated core on obsidian thin sections used for hydration dating. The technique utilizes a gypsum nccessory plate. The gypsum plate rotates all incoming light by 550nm causing the black isotropic core of the nhsidian to become transparent first‐order pink and interacting with the transmitted light from the biref…
