The fine-grain is due to quick cooling magma. Obsidian under the microscope showing a complex fine-grained texture. Another benefit to using obsidian scalpels is the reduction of healing time for surgical incisions. Given these unique characteristics a German company has created surgical tools that allow doctors to use obsidian instruments on patients who might be allergic to steel.
It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts. Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. Because of its sharp edges early man used it to make cutting tools or arrowheads. Obsidian has a conchoidal (shell-like pattern) fracture, which means that it breaks like glass and does not form any flat crystal facets. The primary tool used in this procedure is a sharp razor. Obsidian is considered more of an igneous rock than a mineral, since glass does not have the crystal structure that defines minerals. A shave excision is a simple procedure that your doctor can use to remove growths, such as moles, lesions, and tumors, from your skin. Obsidian hand sample showing the glassy texture. The result is a silicon dioxide glass with magnesium and iron to give it the dark color. Obsidian is a volcanic glass created when magma is extruded from a volcano and quickly becomes quenched (cooled) so that crystals have almost no time to grow. Today’s featured rock/mineral piece is on: Obsidian.
