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.
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.
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
No.because calcite is softer then feldspar
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.
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.
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 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).
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.
Anything under the 7 of the Moh's Hardness Scale, which is the number assigned to quartz. Minerals that can scratch quartz include topaz, corundum and diamond - pretty much everything else won't scratch it.
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
No.because calcite is softer then feldspar
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.
Yes, barite is a relatively soft mineral with a Mohs hardness of 3-3.5, so it can be easily scratched by harder minerals. It is unlikely to scratch most common minerals or rocks, but can be scratched by harder minerals such as quartz or topaz.
Talc is the softest mineral on the Mohs scale with a hardness of 1, so it can be easily scratched by harder minerals. Talc can scratch over minerals with a lower hardness value, but it cannot scratch minerals that are harder than itself, such as quartz or diamond.
There are many minerals with hardness above 5.5 but the standard ones are feldspar,quartz, topaz, corundum and diamond.
