Why is mineral hardness important? - FindAnyAnswer

2020-4-4  Why is mineral hardness important? The softest minerals have metallic bonds or even weaker van der Waals bonds as important components of their structure. Hardness is generally consistent because the chemistry of minerals is generally consistent. Hardness can be tested through scratching. A mineral can only be scratched by a harder substance.
