The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
It is about 2.5 in the Mohs Hardness Scale.
The fourth mineral on Mohs' Scale of Hardness is fluorite. It has a hardness of 4 on the scale.
Jadeite has a hardness of around 6.5 to 7 on the Mohs scale of hardness. This makes it a relatively tough and durable gemstone, suitable for use in jewelry and ornamental objects.
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
The Mohs scale is used to determine the relative hardness of minerals.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
It's called the Ore
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
Azurite has a hardness of 3.5 to 4 on the Mohs hardness scale.
flint is a type of quartz, so it has a hardness of about 7 on the mohs scale of hardness
Nickel has a hardness of 4 on the Mohs scale.
The hardness is 3-4 on Mohs scale.
Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.
This scale was proposed by the Austrian geologist Friderich Mohs.
Aluminum Oxide is roughly 8.5 - 9.0 on the hardness scale.
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
