Obsidian is volcanic glass, derived from the quick cooling of high silica lava.
anythings possible
No, obsidian is also called 'volcanic glass,' since it is a product of cooled lava. Since there are no volcanoes in Louisiana there will not be any natural obsidian.
Obsidian is usually found in caves underground where flowing water hits still lava.
Obsidian cools so quickly the mineral grains do not have time to form.
Obsidian is a hard, dark volcanic rock that is formed by the rapid solidification of lava. Its texture is glassy and shiny black.
The origin is from medievil english. By the way, obsidian is a black mineral.
No. Obsidian is natural glass, mostly silica. Obsidian is of volcanic origin.
Obsidian fragments are known to have some of the sharpest edges possible.

Obsidian is a glass of volcanic origin.
Obsidian is an extrusive igneous rock. Volcanic in origin, it is very common in recent lava flows. Obsidian is primarily made of glass. Obsidian is amorphous, lacking any crystal structure found in gemstones. For more details, try asking the question - "What is obsidian"
Obsidian and granite are both igneous rocks. Obsidian is of extrusive origin (which means the magma cooled quickly) and has a glassy texture. Granite is of intrusive origin (which means the magma cooled slowly) and is phaneritic, or coarse grained.y
5 books: Obsidian, Onyx, Opal, Origin, not titled yet 1 novella: Shadows
It's technically possible but rare for phenocrysts to be found in an obsidian. This would require the magma rising to the surface and cooling quickly.
i don't think it's possible because pistons can't push or pull (with sticky pistons) obsidian and bedrock.( i tried to do it to make a bank vault)
Obsidian is a naturally occurring volcanic form of glass.
