What are the properties of obsidian rock?
obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre and is slightly harder than window glass.
What is the rarest color of obsidian?
Obsidian Information Data Value Colors Black; gray, banded with brown streaks. Green, blue, and reddish stones (transparent) are very rare. Iridescence noted: gold, silver, blue, violet, green, and combinations of these colors, due to inclusions of minute bubbles that reflect light.

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). Basic glasses are reported to be more magnetic than acid glasses (George, 1924:370).

Why is obsidian smooth?
That’s because obsidian is volcanic glass. It forms when volcanic lava cools so quickly, there’s no time for crystals to grow. This gives the rock a black, smooth, glossy shine. Since obsidian forms from magma, it is an igneous rock.
What is the story behind Apache tears?

How sharp can obsidian get?
Cutting edge Obsidian – a type of volcanic glass – can produce cutting edges many times finer than even the best steel scalpels. At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge.
Is obsidian conductive?
The mineral has no electrical conductivity, is not radioactive, and melts at a temperature of 1200 to 1500 degrees Celsius.

Obsidian is quite unique due to its smooth, uniform volcanic glass texture. Obsidian is usually considered an extrusive rock, because it usually solidifies above Earth’s surface where the edges of a lava flow come into contact with cool air or water. Geologists call the way obsidian breaks a conchoidal fracture.
