Obsidian is actually a naturally occurring volcanic rock. It has a glass-like appearance and is formed when lava from the volcano solidifies so quickly that it bypasses the crystallisation process.
Obsidian cannot float on water. It has a specific gravity about 2.5, meaning it is about two and one-half times as heavy as water and will sink if immersed.
No. Obsidian is brittle.
One type of obsidian is snowflake obsidian, which is black with white mineral inclusions that resemble snowflakes.
Obsidian is a naturally occurring volcanic glass and is not permeable, meaning that water and other fluids cannot easily pass through it. This property makes obsidian a popular material for making sharp tools and weapons in the past.
Obsidian is not magnetic.
