Obsidian is naturally occurring volcanic glass. It usually contains variable amounts of impurities (which is why it is typically black). Pure silica glass has a hardness (on the Mohs hardness scale) of 5.5. Obsidian is often a bit softer than pure...
What is Moh's Hardness Scale. According to the Mineralogical Society of America, Moh's Hardness Scale was developed by Frederich Mohs in 1822. The purpose of the scale is to determine how scratch resistant a mineral is and is related to the breaking of chemical bonds in the material as well as microfractures on the surface.

The Mohs scale of mineral hardness is an ordinal scale that tests the hardness of minerals based on their ability to scratch softer materials. The Mohs scale runs from 1 (softest) to 10 (hardest). Talc has a Mohs hardness of 1, while diamond has a hardness of 10. The Mohs scale is only one hardness scale.
