Obsidian, or "volcanic glass," is made when molten rock comes out of a volcano and cools so quickly that no crystalline structure has time to form. This makes obsidian an extrusive igneous rock. The cooling occurs right at the surface.
Yes, obsidian can be melted to create glass objects. Obsidian is a natural volcanic glass that can be heated to high temperatures to become molten and then shaped into various glass objects.
Obsidian is a naturally occurring volcanic glass composed primarily of silicon dioxide, which is a compound made up of the elements silicon and oxygen. Therefore, obsidian is not an element but a mixture of elements in compound form.
Obsidian does not react with acid. Igneous rocks in general rarely react with acid.
Yes, obsidian can be melted and reshaped into different forms due to its glass-like properties.
Obsidian is a natural glass that can form sharp edges when broken, known as obsidian flakes. However, whether it flakes in your hand would depend on the force applied and the specific condition of the obsidian. Generally, obsidian will flake if enough pressure is applied to break it.
Obsidian is a natural glass.

The common name for obsidian rock is volcanic glass.
No. Obsidian is volcanic glass. Glass is amorphous and thus noncrystalline.
Yes, obsidian can be melted to create glass objects. Obsidian is a natural volcanic glass that can be heated to high temperatures to become molten and then shaped into various glass objects.
Obsidian is an extrusive felsic igneous rock.
No, obsidian is volcanic glass.
Obsidian, due to its glassy texture made from the super-cooling process.
Other names for obsidian is Apache tears, volcanic glass, and Black obsidian.
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 is a form of glass. Glass can only form when material cools from a molten state.
Yes, Obsidian is known as volcanic glass. It is a natural glass formed from rapidly cooled lava, typically from volcanoes. Obsidian has a shiny appearance and is commonly used in jewelry and tools due to its sharp edges when fractured.
