Review Minerals-7

I used this piece of quartz to scratch a piece of glass. What was I testing?

  1. Streak

    No. To test streak, you rub the mineral on a white tile, to see its color when it is powdered.
  2. Fracture

    No. Fracture is one way that minerals can break. I am not breaking the mineral.
  3. Hardness

    Yes. Hardness is measured by scratching other substances, such as your fingernail, copper, and glass. This quartz scratches the glass, which tells us it has a hardness or 5.5 or more. Actually, the hardness of quartz is 7, quite a bit harder than glass.
  4. Cleavage

    No. Cleavage is one of the ways that minerals can break. I am not breaking the mineral.
