No one knows my namestake like I do (except Crystallography majors) and in reality obsidian is not quite classified as a type of crystal at all, as its composition is too complex to comprise a single mineral, it's usually just considered a mineraloid.
Obsidian does not have cleavage because of the way it forms. Obsidian is essentially nature's form of glass and so it has no regular or patterned crystal structure. Without that crystal structure, there is no cleavage.
Obsidian falls under the group of Extrusive Volcanic Rock of very fine texture. Obsidian is generally called Volcanic Glass.
Yes, obsidian exhibits conchoidal fracture, which is a smooth, curved breakage pattern characterized by concentric ridges. This is due to its lack of internal crystal structure, which causes it to break in a unique, curved manner.
Yes, obsidian is a naturally occurring volcanic glass formed when lava cools rapidly, often with minimal crystal growth. It is commonly black in color and has been used historically for tools and decorative items due to its sharp edges when fractured.
Obsidian, which is volcanic glass, is a good example.
yes obsidian is a crystal.
Obsidian is in the Igneous rock group.

Quartz belongs to the hexagonal crystal system.
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 falls under the group of Extrusive Volcanic Rock of very fine texture. Obsidian is generally called Volcanic Glass.
Volcanic glass or obsidian is a quickly cooled igneous rock without a mineral crystal structure.
Yes, obsidian exhibits conchoidal fracture, which is a smooth, curved breakage pattern characterized by concentric ridges. This is due to its lack of internal crystal structure, which causes it to break in a unique, curved manner.
Obsidian is neither an element nor a compound. It is a naturally occurring volcanic glass formed when lava cools rapidly without crystal growth.
Obsidian cools relatively quickly compared to other types of volcanic glass due to its composition and the rapid cooling process during its formation. The rate of cooling affects the crystal structure and appearance of the obsidian, leading to its characteristic smooth and glassy texture.
Granite is a coarse grained igneous rock without Pyroxene.
