Fluorite has a hardness of 4 out of 10 and can scratch gypsum, talc and anything less than 4.
Mohs' Scale of mineral hardness using minerals is :-TalcGypsumCalciteFluorite (also known as Fluorspar)ApatiteOrthoclase FeldsparQuartsTopazCorundumDiamondThus minerals 5,6,7,8,9 and 10 will 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.
A steel knife can scratch minerals with a hardness lower than that of steel, such as gypsum, calcite, fluorite, and talc. Minerals like quartz, topaz, and corundum are harder than steel and cannot be easily scratched by a steel knife.
A steel file can scratch minerals with a hardness of 6.5 or lower on the Mohs scale. This includes minerals such as gypsum, calcite, and fluorite.
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
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.
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
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.
Yes, fluorite can scratch apatite. Fluorite is harder than apatite on the Mohs scale, which means it has the ability to scratch apatite.
Feldspar is harder than fluorite on the Mohs scale of mineral hardness. Feldspar has a hardness of about 6 to 6.5, while fluorite has a hardness of 4. This means that feldspar can scratch fluorite, making it the harder of the two minerals.
Quartz has a Mohs hardness of 7, meaning minerals that are softer than quartz (Mohs < 7) will not be able to scratch it. Some examples include talc (Mohs 1), gypsum (Mohs 2), calcite (Mohs 3), and fluorite (Mohs 4).
