What minerals can a steel knife scratch?
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.
Which minerals will not scratch quartz?
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).
What minerals you could use to scratch fluorite?
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.
Which minerals can scratch apatite?
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.
What minerals scratch calcite?
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
Which minerals would scratch fluorite?
Minerals that can scratch fluorite include quartz, topaz, corundum, and diamond. These minerals have a higher hardness on the Mohs scale, which means they are able to scratch fluorite.
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.
What minerals would scratch fluorite - talc quartz or calcite?
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
Will fluorite scratch a penny?
No, fluorite is softer than a penny on the Mohs scale of mineral hardness. Fluorite ranks around 4 on the scale, while a penny ranks around 3.5, so fluorite will not scratch a penny.
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 can Garnet scratch?
Garnet, a mineral with a hardness of 6.5-7.5 on the Mohs scale, can scratch materials with a hardness lower than itself, like glass, steel, and softer minerals such as calcite and fluorite.
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.
