Comment on this resource
This web site provides a tutorial on how to test the hardness of a mineral. The hardness of a mineral is one of the most diagnostic and easy tests to perform in the attempt to identify an unknown mineral. Hardness is a measure of a mineral's resistance to abrasion and reflects the atomic structure of a mineral. A comparative hardness scale is also provided.
