Fluorite has a Mohs hardness of 4, meaning it can be scratched by objects with a hardness greater than that. Two common objects that can scratch fluorite are quartz, with a hardness of 7, and topaz, which has a hardness of 8. These minerals are significantly harder than fluorite and will easily leave scratches on its surface.

What two objects that will scratch Fluorite?
Fluorite has a hardness of 4 on the Mohs scale, meaning it can be scratched by objects that have a hardness greater than 4. Two common objects that can scratch fluorite are quartz (hardness 7) and topaz (hardness 8). These minerals are significantly harder than fluorite and can easily create scratches on its surface.
What mineral would scratch apatite but not scratch fluorite?
The mineral that would scratch apatite but not scratch fluorite is quartz. Quartz has a hardness of 7 on the Mohs scale, while apatite has a hardness of 5 and fluorite has a hardness of 4. Therefore, quartz can scratch apatite but is too hard to be scratched by fluorite.
Why can copper scratch fluorite?
Copper can scratch fluorite because of the difference in their hardness levels, as measured on the Mohs scale. Fluorite has a hardness of 4, while copper has a hardness of around 3.5. Since a harder material can scratch a softer one, copper can easily scratch the surface of fluorite.
What is a mineral that fluorite can't scratch?
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
What mineral is hard enough to scratch calcite but no hard enough to scratch amphibole?
Fluorite is a mineral that is hard enough to scratch calcite, which has a hardness of 3 on the Mohs scale, as fluorite has a hardness of 4. However, fluorite cannot scratch amphibole, which typically has a hardness ranging from 5 to 6. Thus, fluorite fits the criteria of being harder than calcite but softer than amphibole.

Two common objects that can scratch fluorite are quartz (hardness 7) and topaz (hardness 8). These minerals are significantly harder than fluorite and can easily create scratches on its surface.
Can fluorite scratch apatite?
Yes, fluorite can scratch apatite. Fluorite is harder than apatite on the Mohs scale, which means it has the ability to scratch apatite.
What mineral would scratch apatite but not scratch fluorite?
The mineral that would scratch apatite but not scratch fluorite is quartz. Quartz has a hardness of 7 on the Mohs scale, while apatite has a hardness of 5 and fluorite has a hardness of 4. Therefore, quartz can scratch apatite but is too hard to be scratched by fluorite.
Why can copper scratch fluorite?
Copper can scratch fluorite because of the difference in their hardness levels, as measured on the Mohs scale. Fluorite has a hardness of 4, while copper has a hardness of around 3.5. Since a harder material can scratch a softer one, copper can easily scratch the surface of fluorite.
Fluorite can scratch which minerals?
Fluorite has a hardness of 4 out of 10 and can scratch gypsum, talc and anything less than 4.
Will fluorite scratch a penny?
no because fluorite is softer than a penny
What is a mineral that fluorite can't scratch?
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
Is fluorite harder than calcite?
Yes, fluorite is harder than calcite. Fluorite has a hardness of 4 on the Mohs scale, while calcite has a hardness of 3. This means that fluorite can scratch calcite, but calcite cannot scratch fluorite.
What mineral is hard enough to scratch calcite but no hard enough to scratch amphibole?
Fluorite is a mineral that is hard enough to scratch calcite, which has a hardness of 3 on the Mohs scale, as fluorite has a hardness of 4. However, fluorite cannot scratch amphibole, which typically has a hardness ranging from 5 to 6. Thus, fluorite fits the criteria of being harder than calcite but softer than amphibole.
Which mineral will scratch fluorite galena and pyroxene?
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
Which minerals would scratch fluorite?
Any mineral with a hardness greater than that of fluorite which is 4 on the Mohs scale of hardness. Examples include quartz, orthoclase, garnet, diamond, etc.
What can scratch fluorite?
Fluorite is a relatively soft mineral with a Mohs hardness of 4, so it can be scratched by harder materials like quartz, topaz, and corundum. However, fluorite can scratch materials with a lower hardness, such as gypsum and calcite.
