Chinese, Choctaw, Comanche, Digueno, The Birth of Hawaii, and Hindu creation myths. These characteristics have made it an ideal material for tool making for over 700000 years. It has very high tensile strength but is also very brittle due to low compressive strength. The technique of obsidian-hydration dating presupposes that a fresh surface is created when an obsidian tool is flaked. Obsidian’s unique weathering properties are helping to establish the age of obsidian artifacts. and when I tried to take it off the foam just broke apart and created a mess. Obsidian scalpels are now used in specialized eye surgery and neurosurgery procedures. Obsidian is rated at 5 to 5.5 on the Mohs scale of mineral hardness with diamond rated at 10 and talc rated at 1. Buy 13 OBSIDIAN BLADE DRAGON ATHAME DAGGER KNIFE: Knives.
