![]() ![]() Today’s featured rock/mineral piece is on: Obsidian. 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. i would personally prefer an obsidian razor to any other- corrosion resistance + sharpness forever blade deleted 9 yr. the stainless steel would need a lot of resharpening before the obsidian blade even began to show signs of wear. The result is a silicon dioxide glass with magnesium and iron to give it the dark color. Lets consider that the longevity of a stainles steel (surgical steel) to obsidian. The shape altered according to need such that earlier ablative and amputation requirements were long and durable. ![]() In addition, titanium, ceramic, diamond, and even obsidian blades are possible.

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 is considered more of an igneous rock than a mineral, since glass does not have the crystal structure that defines minerals. The primary tool used in this procedure is a sharp razor. ![]() Obsidian has a conchoidal (shell-like pattern) fracture, which means that it breaks like glass and does not form any flat crystal facets. Because of its sharp edges early man used it to make cutting tools or arrowheads. Some serrations near the blade attachment area to provide better grip for surgeon. Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. The number three handle is most commonly used in surgical specialties: Flat shape. 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. 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. Another benefit to using obsidian scalpels is the reduction of healing time for surgical incisions. Obsidian under the microscope showing a complex fine-grained texture. The fine-grain is due to quick cooling magma. ![]()
