Disadvantages: It is less useful for silicate minerals, most of which have a white streak or are too hard to powder easily. Calcium carbonate reacts with an acid to produce bubbles on the surface of the crystal. Feldspars are hard minerals, all of them with a hardness of 6 on the Mohs scale. Based on the region it is measured, strength may be either yield strength (maximum stress in elastic region) or . Cleavage is the tendency of the mineral to break along a flat planar surfaces due to its structure of the crystal lattice.
