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.
You certainly can test the hardness of chicken bones before and after they are soaked in liquid. You can try tapping and bending them for example.
diamonds are hard because they cannot be scratched.
no one likes your Hardness! hardness is not a good character.
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
It is hardness. Calcite is harder than gypsum.
Talc Diamond Quartz
Anything higher on the hardness scale for example if limestone has a hardness of 4 then it would take something with a hardness of 4 or higher to scratch it.
Diamonds are listed on the Mohs Scale of hardness, and occupy the hardest rating at 10.
We use Mohs scale of mineral hardness to access the hardness of minerals, which calcite is one example.
For example talc is very soft.
