They represent a valuable sample of the range of mineral hardness found as measured in the Mohs' scale. These minerals are also of great value in the abrasives industry from the kaolin clays and the similar industrial properties of talc, to sandpapers using garnets and quartz for their hardness and low cost. All of these items play a significant part in the glass industry as well. I could go on and on, these minerals tend to be seen used together in a multitude of ways today.
