METHODS USED TO IDENTIFYING MINERALS

The hardness of a mineral can be measured by its resistance to scratching or abrasion. The Mohs scale is a set of 10 common minerals chosen for comparative hardness. The minerals are arranged in order of increasing hardness; each mineral will scratch all that precedeit, and be scratched by all that follow it. The Mohs scale is as follows:
