What is harder a steel file can scratch a penknife blade or calcite scratches a copper coin?
Calcite scratching a copper coin is harder because calcite has a higher Mohs hardness scale rating than copper. Steel files can scratch penknife blades because steel is harder than the blade material, which is usually softer.
What mineral can scratch glass but can be scratched by steel file?
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.
What minerals can steel file scratch?
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.
What mineral can scratch glass but not steel file?
n
Can a steel file scratch muscovite?
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.
Would a steel file be able to scratch quartz?
yes
How can one determine the hardness of minerals and what methods are used to test it?
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.
Which object can scratch feldspar but not quartz?
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.
Can a steel file scratch calcite?
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.
How do you find hardness of an unknown mineral?
There are two ways. One way is to buy a scratch test kit and follow the instructions. They will tell you to try to scratch minerals of certain hardnesses and find the hardest one it can scratch. For example, if it scratches a mineral with a hardness of 6 but not one with a hardness of 7, the hardness would be between 6 and 7. If you do not have one of those available, you can try scratching common objects. Your fingernail is 1.5, a penny is 2.5, a pocketknife blade is 5.0, window glass is 5.5, a steel file is 6.5, and quartz is 7.0.
Can a rectangular file cut wood metal and plastic?
yes, it is possible although it seems like a bit of a stupid question to ask really as that is what a rectangular does, note the file is not for steel it can only be used on soft aluminum and soft metals such as copper. steel and iron would simply wear out the file and probably make sparks too.
What type of mineral has various colors almost clear appeared to have hexagonal crystals and is hard enough to scratch a steel file?
The mineral you are describing is likely quartz, particularly in its clear or colorless form, known as rock crystal. Quartz exhibits a hexagonal crystal structure and is relatively hard, scoring a 7 on the Mohs scale, which allows it to scratch a steel file. Its various colors can arise from impurities or inclusions, leading to varieties such as amethyst or citrine.
