Orthoclase is most widely known as the pink feldspar found in many granites and as the mineral assigned a hardness of "6" in the Mohs hardness scale. Because of these similarities, the feldspar minerals can be challenging to identify with absolute confidence in the field or the introductory classroom. When minerals react, the products will sometimes assume the shape of the reagent; the product mineral is termed a pseudomorph of (or after) the reagent. Join now.
