Potassium feldspar is a member of the feldspar mineral family. Like Flagioclase Feldspar, potassium feldspars are silicate minerals that contain a considerable amount of potassium. Feldspar crystals are stubby prisms, often pink to white. Some potassium feldspars, such as the one shown to the left have a streaky appearance (see closeup) called perthitic texture.[1]
