Natural glass can be made by combining sandstone, limestone and lime under high heat until it melts, pouring in into a mould and allowing it to cool slowly, or by picking a globule up on a hollow tube and blowing into it to make a bubble.
Glass made by this method tends to be of a poor quality, with inclusions (floaties) and air bubbles. It also tends to be exceptionally brittle if it cools unevenly.

What is true about volcanic glass?
Volcanic glass is the amorphous (uncrystallized) product of rapidly cooling magma.
What is the common name for obsidian rock?
The common name for obsidian rock is volcanic glass.
Is volcanic glass made from slower or faster cooling lava?
Volcanic glass, such as obsidian, is formed from lava that cools rapidly. This rapid cooling prevents the formation of crystalline structures, resulting in a glassy texture. In contrast, slower cooling allows crystals to form, leading to different rock types like basalt or granite. Thus, volcanic glass is associated with faster cooling lava.
Is Obsidian known as volcanic glass?
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.
How much is a pound of volcanic glass worth?
The value of volcanic glass, such as obsidian, can vary based on factors such as quality, size, and demand. On average, a pound of volcanic glass may range from a few dollars to around $10-$20. Rare or unique specimens could potentially be worth more to collectors or for specialized uses.

What type of rock is volcanic glass?
Siliceous volcanic glass is also known as obsidian.
Are the atoms in volcanic glass organized or disorganized?
The atoms in volcanic glass are highly disorganized.
Is volcanic glass a mineral?
Volcanic glass is not a mineral. It's composition is complex, and their is no crystalline structure.
What is true about volcanic glass?
Volcanic glass is the amorphous (uncrystallized) product of rapidly cooling magma.
What is considered to be volcanic glass?
Obsidian, due to its glassy texture made from the super-cooling process.
What is the common name for obsidian rock?
The common name for obsidian rock is volcanic glass.
Is volcanic glass full of air spaces?
Not necessarily. Scoria and pumice are forms of volcanic glass that contain air spaces, while obsidian, another volcanic glass, contains minimal air spaces if any.
Is volcanic glass a Granite?
No. Granite cools from magma deep underground. Volcanic glass cools quickly at or near the surface.
Can volcanic ash dissolve in rain?
Yes ash does ash is made of tiny jagged pieces of rock and glass.
Is pumice a element or compound?
Pumice is neither an element nor a compound. It is a type of volcanic rock that is made up of various minerals and volcanic glass.
