Basically, the mineral properties which can be used to test and identify a mineral include the following:
Generally, the hardness of a mineral can be tested by scratching its surface with a knife or your nails.
In this scenario, you were given a sample of quartz, which has a hardness of seven (7).
We can use quartz to determine the hardness of other minerals by using it (quartz) to scratch their surface. For any mineral, which has its hardness below seven (7), its surface would be scratched by quartz.
However, if the mineral scratches the surface of quartz, it then means that mineral has a hardness above seven (7).
