Physical properties of feldspar minerals: Feldspar minerals have amazingly consistent physical properties. Most of the minerals in the feldspar have two courses of good cleavage that converge at nearly right angles. Along with having the same inclination angle for their cleavages, they also possess the same specific gravity and Mohs firmness.
