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.
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
No.because calcite is softer then feldspar
Diamonds are proven to scratch all minerals including itself.
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.
Topaz has a hardness of 8 on the mohs scale.A steel file has a hardness of 6.5, or maybe 7+ if it has been hardened.In theory, the topaz is likely to be harder than the average steel file.=== === ...you may want to avoid putting this to the test, because, although you might scratch the steel file with the topaz, you might also just damage your topaz in the process, because, who knows, maybe your steel file is made of best high-carbon steel, which has a hardness of 8 on the mohs scale!And then there are steel files that have a layer of tungsten-carbide welded to the cutting surface. Tungsten-carbide has a mohs rating of 8.5 to 9! * For more information, see 'Related links' below this box.
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.
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.

Yes, a steel file can scratch muscovite because muscovite has a Mohs hardness of 2.5-3, while a steel file typically has a hardness of around 6.5. Harder materials can scratch softer materials according to the Mohs scale of mineral hardness.
yes
The copper of the penny will rub off the file
No.because calcite is softer then feldspar
A steel nail can scratch feldspar but not quartz. Feldspar has a hardness of 6 on the Mohs scale, while quartz has a hardness of 7.
The hardness of minerals can be determined using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest). To test hardness, one can scratch a mineral with a known hardness or use a tool like a fingernail, copper penny, or steel file to compare the resistance to scratching.
Diamonds are proven to scratch all minerals including itself.
Diamond is harder than steel: you can scratch steel with a diamond, but steel will not scratch a diamond.
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.
