What is the characteristic of a mineral that is revealed by testing what substances can scratch it and what the mineral can scratch?
it is hardness
What is a mineral's ability to scratch another mineral?
A mineral's resistance to being scratched (or when a force is applied) is called its hardness.There are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. A material's hardness depends on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
What is the only mineral that can scratch corundum?
Diamond is the hardest mineral and is the only one that can scratch corundum. but in my opinion corundum will scratch corundum any mineral of the same hardness will scratch the other !
How would a mineral collector determine the hardness of an unknown mineral specimen?
There are two ways. One way is to buy a scratch test kit and follow the instructions. They will tell you to try to scratch minerals of certain hardnesses and find the hardest one it can scratch. For example, if it scratches a mineral with a hardness of 6 but not one with a hardness of 7, the hardness would be between 6 and 7. If you do not have one of those available, you can try scratching common objects. Your fingernail is 1.5, a penny is 2.5, a pocketknife blade is 5.0, window glass is 5.5, a steel file is 6.5, and quartz is 7.0.
Describe how to find the hardness of unknown mineral?
Minerals are tested for hardness by performing a scratch test. The unknown mineral is scratched with another object that the hardness is known. For example, a unknown mineral may be scratched with a piece of metal to compare the resistance.

What mineral can scratch a diamond?
diamond's hardness is a factor of 10. So this is the highest hardness, no mineral has this hardness! You can't scratch a diamond.

To what are you referring when you address the hardness of a mineral?

What is it called when you perform a scratch test on a mineral?
It is called a streak and its purpose is to find the hardness of the mineral.
A minerals hardness with respect to other minerals can be determined by?
scratching the mineral acrros a glass plate
How difficult or easy it is to scratch a mineral?
hardness
What is the hardness of a mineral if it scratches a penny but will not scratch glass?
Between 3.5 and 5.5 on the Mohs scale of mineral hardness.
What do scientists use to determine mineral hardness?
The Mohs scale of mineral hardness is generally used to determine the hardness of a mineral. The Mohs scale rates the ability of mineral to scratch or be scratched by another mineral.
How hardness defined when identifying minerals?
Hardness is the ability of a mineral to resist being scratched. A diamond is the hardest mineral--which means that no other mineral can scratch it.

What kind of mineral can scratch quartz but not diamond?
According to the Mohs scale of hardness, Diamond has a hardness of 10 and Quartz has a hardness of 7. Any mineral with a hardness greater than 7 can scratch quartz and diamond can scratch any mineral with a hardness less than 10. Corundum (hardness of 9) and Topaz (hardness of 8) are two examples of minerals that can scratch quartz but not diamond.
