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.
No, gypsum cannot scratch topaz. Minerals with a higher number on the Moh's Hardness Scale can scratch minerals that are lower-numbered, but lower numbers can't scratch higher numbers. A mineral would have to have a number higher than an 8 on the Moh's hardness scale in order to 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.
I dont know, I have been seacrching Google myself!! :(
The mineral that can scratch garnet is topaz. On the Mohs scale of mineral hardness, garnet has a hardness of about 6.5 to 7.5, while topaz has a hardness of 8. This means that topaz is harder than garnet and can scratch it. Other minerals with a higher hardness, such as corundum (which includes sapphires and rubies), can also scratch garnet.
Three minerals that can scratch quartz are topaz, corundum, and diamond. Topaz has a hardness of 8 on the Mohs scale, while corundum, which includes sapphires and rubies, has a hardness of 9. Diamond, the hardest natural material, ranks 10 on the scale, making it capable of scratching all other minerals, including quartz, which has a hardness of 7.
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.
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
There are many minerals with hardness above 5.5 but the standard ones are feldspar,quartz, topaz, corundum and diamond.
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.
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.
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
