Diamond is the hardest mineral, with a Mohs hardness of 10. Talc is the softest mineral, with a hardness of 1. The Mohs scale is ordinal, where the relative hardness values between one number and another are not uniform For example, diamond (10) is four times harder than corundum (9), while corundum is twice as hard as topaz (8).

These include rock strength, rock structures (e.g., fracture frequency), and rock density. This research also showed that the BWi is well correlated with rock strength and rock density. Therefore, some scholars have used the BWi as an index to define the hardness and the blastability of a rock mass to optimize blast design [39, 40].
