Obsidian is a volcanic glass that occurs naturally as an extrusionary igneous rock. Obsidian is a massive glass of volcanoes. This word is’ huge,’ but it does mean in geology that stone (obsidian is rocky, not a mineral) is homogeneous, though this is connected to geologies. Laying, ...
The white "m" on a piece of M&M's candy is a titanium oxide pigment, most likely produced from the mineral rutile. Structure of the mineral halite: The mineral "halite" has a chemical composition of NaCl. That means it contains equal numbers of sodium and chloride atoms. In this case...
Obsidian is mineral-like, but not a real mineral because it is not crystalline as a glass ; moreover, its composition is too variable to be classified as a mineral. It’s classified as a mineraloid sometimes. Obsidian Properties Varieties: Apache Tears, Fire Obsidian, Mahogany Obsidian, Rainb...
