Basalt scores an 8 on the Moh's scale. This makes it harder than quartz and vanadium, but weaker than boron and titanium carbide. It can easily scratch steel and glass. It is just about as hard as topaz. Basalt is also an igneous rock, formed by hardened lava, which explains why it is so hard.
Topaz is number 8 on the Mohs scale.
The softest material in the mohs scale is talc
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
The fourth mineral on Mohs' Scale of Hardness is fluorite. It has a hardness of 4 on the scale.
Yes, lime stone is 3 - 4 on the Mohs scale, Bassalt is 7 on the Mohs scale.
Plagioclase feldspars which are a component of basalt has a hardness of around 7 on the Mohs Scale.
This scale was proposed by the Austrian geologist Friderich Mohs.
It's called the Ore

Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
The hardness is 3-4 on Mohs scale.
Nickel has a hardness of 4 on the Mohs scale.
Topaz is number 8 on the Mohs scale.
The Mohs scale compares the hardness of an object or substance.
Oh, dude, basalt has a hardness of around 6 on the Mohs scale. It's not the softest thing out there, but it's not exactly diamond-level tough either. So, like, if you're thinking of using it to scratch your back, maybe stick to a loofah instead.
