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. Is obsidian magnetic The magnetic properties of obsidian have been recognized by geologists for some time and the causes subject to investigation (e.g., Schlinger et al., 1986). 4 MM thick, meaning it doesnt cut between the cells. Obsidian is used by some surgeons for scalpel blades, although this is not approved by the US Food and Drug Administration (FDA) for use on humans. specimens still exist, showing it to be similar in principle to those used by the Australians. Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. Answer (1 of 2): An obsidian blade is 3 nanometers thick, capable of cutting BETWEEN your cells, allowing for a much more painless surgery. Obsidian and rock crystal were also used for knife making. 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.

Obsidian is considered more of an igneous rock than a mineral, since glass does not have the crystal structure that defines minerals. Obsidian hand sample showing the glassy texture. Modern artisans still scratch their heads trying to figure out how the Aztecs produced the paper-thin disks they sometimes used as earrings and pendants. The result is a silicon dioxide glass with magnesium and iron to give it the dark color. Scar width, however, was significantly less in the obsidian wounds at 7, 10, and 14 days (p < 0.005). Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days.
OBSIDIAN SCALPEL ARE THEY STILL USED TODAY SKIN
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. Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. Today’s featured rock/mineral piece is on: Obsidian.
