The Mohs scale of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Wikipedia

What is a 10 on the hardness scale
The only range of relative Mohs hardness, diamond, is actually rated at 10. This means that this species is the hardest mineral known to mankind. One mineral, possibly having the same degree of hardness, has the potential to scratch the mineral.
What is the highest hardness level
For industrial products, it is better to use other resistance measurements. Diamond is still at the top of the scale and seems to be the hardest mineral. There are 10 minerals on the Mohs scale, talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, corundum, topaz and last and worst diamond.

How is Vickers hardness test different from other hardness tests
When using a diamond bonded indenter, the Vickers stress test is performed with less stress and greater accuracy than the Brinell test. … Because it requires an optical computer and hardware training, the Vickers test is more expensive and time consuming than the Rockwell test.
What is the difference between total hardness and calcium hardness
What is “calcium hardness” and therefore “total hardness” and what is the difference? Calcium hardness is the level of dissolved calcium in spa or pool water. Total hardness, which in turn is measured using various test packages, measures both the calcium present in the water and the mineral magnesium.
How will you determine the tablet hardness using a hardness tester
Most tablet resistance testers work by simply moving a rod or sponge that clamps the device between two solid plates, causing the vacuum to break, not to mention determining the action required.
Is total hardness the same as calcium hardness
The overall hardness is probably called calcium hardness or total hardness. Total hardness is an estimate of the amount of calcium and magnesium dissolved in hot spa water. … Higher total alkalinity or pH levels require lower calcium hardness to reduce scale formation.
What is hardness explain the types of hardness
Hardness, as you can see, is defined as the concentration of calcium and ions of these minerals, expressed in terms of lime carbonate. These minerals in the water can cause everyday problems. … There are two types of water hardness, so the time constant is.
