yes
No, you generally cannot scratch shale with your fingernails. Shale is a sedimentary rock that is relatively hard and composed of clay minerals, making it more resistant to scratching. Fingernails have a hardness of about 2.5 on the Mohs scale, while shale typically has a hardness of around 3 to 4. Therefore, a fingernail would not be able to leave a scratch on shale.
From a flooring installer, I would say replace the tile however you may be able to fix the scratch with some of the stuff they use to fix scratches on cars....
Unlike wood, steel will not rot. It will hold in place, and not blow off very easily. Steel proves to be a very strong and long lasting material. It is also able to with hold many weather conditions.
They would not be able to move as well! LOL
Food would be able to enter the lungs.
Apatite is a mineral that can scratch feldspar but not quartz. This is because apatite has a higher hardness value than feldspar but a lower hardness value than quartz on the Mohs scale of mineral hardness.
Yes, diamonds are harder than quartz on the Mohs scale, so diamonds can scratch quartz.
topaz has a hardness of 8 on the mohs hardness scale, quartz has a hardness of 7. topaz will be able to scratch quartz, but quartz can never scratch topaz.
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
Yes, quartz is considered a hard mineral ranking 7 on the Mohs scale of hardness, making it able to scratch most other minerals. However, there are harder minerals such as diamond and corundum that can scratch quartz.
Quartz will scratch glass, as its hardness is usually around 7. Pyrite, on the other hand, has a hardness of 6 to 6.5, meaning it would not be able to scratch glass.
Citrine is a form of quartz. Quartz will scratch glass.
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.
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).
Emeralds have a hardness of around 7.5-8 on the Mohs scale, so minerals with a higher hardness like corundum (9) and diamond (10) can scratch emeralds. Minerals with a lower hardness, such as quartz (7) and feldspar (6), would not be able to scratch an emerald.
I would guarantee that diamond would scratch it, and types of corundum like rubies, sapphires and raw corundum probably would, because it is 9 on the moh's scale of hardness. Quartz, emerald, agate and topaz would also scratch it.
Qtz is a 7 on Mohs Hardness scale. So it can scratch itself or anything less on the scale. Just that simple.
