A typical steel knife would be in the 5-5.5 range on the Mohs scale.
A paper clip is typically made of steel, which has a Mohs hardness of around 5.5 to 6.5. Therefore, a paper clip would have a hardness of around 5.5 to 6.5 on the Mohs hardness scale.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
It's called the Ore
Copper. Copper has a hardness of 2.5-3 on the Mohs scale, while a steel knife generally has a hardness of around 5.5 - 6.5. This means that a steel knife can scratch copper, but a copper penny cannot scratch a steel knife.
Azurite has a hardness of 3.5 to 4 on the Mohs hardness scale.
Stainless steel has a hardness level of around 5.5 on the Mohs scale.
The hardness of the mineral pyrite, or Fool's Gold, is about 6 on the Mohs hardness scale. That's a little harder than a steel knife blade, but not as hard as the mineral quartz
Yes, a knife can scratch dolomite because dolomite is relatively soft, with a Mohs hardness of around 3.5 to 4. This means it is softer than the steel blade of a knife, which typically has a hardness of around 5.5 to 6.5 on the Mohs scale.
A paper clip is typically made of steel, which has a Mohs hardness of around 5.5 to 6.5. Therefore, a paper clip would have a hardness of around 5.5 to 6.5 on the Mohs hardness scale.
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.
Copper. Copper has a hardness of 2.5-3 on the Mohs scale, while a steel knife generally has a hardness of around 5.5 - 6.5. This means that a steel knife can scratch copper, but a copper penny cannot scratch a steel knife.
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
The hardness of a steel nail is about 4.5 (About the same hardness of the mineral Fluorite.)
Yes, a knife can cut through talc as talc is a soft mineral with a Mohs hardness of 1 on the Mohs scale. This makes it easy to cut or scratch with a knife because of its low hardness.
