What mineral can scratch feldspar but not quartz?
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.
How hard is orthoclase feldspar?
On the Mohs Scale of mineral hardness, feldspar is 6 and quartz is 7, so quartz is harder. What does this mean? quartz will scratch feldspar, but feldspar will not scratch quartz.
What mineral scratches fluorite but not feldspar?
Quartz scratches fluorite but not feldspar. Fluorite has a relative hardness of 4 on the Mohs scale, while feldspar has a hardness of 6-6.5. Quartz, with a hardness of 7, is harder than fluorite but softer than feldspar, allowing it to scratch fluorite but not feldspar.
Which object can scratch apatite but not feldspar?
Diamond can scratch apatite but not feldspar. This is due to the difference in hardness between the two minerals, with diamond being the hardest natural substance on the Mohs scale at 10, while apatite is around 5 and feldspar is around 6-6.5.

Which mineral on the mohs scale will scratch apatite?
Minerals that will scratch apatite must be more than a 5 on the Moh's hardness scale. So feldspar, quartz, topaz, corundum, and diamond will scratch apatite.
Which mineral can not scratch quartz?
Many mineral can not scratch Quartz.Remember the mnemonic for Mohs' scale of hardens "The Girls Can Flirt And Other Queer Things Can Do", where the mineral for each first letter is:(softest)TalkGypsumCalciteFluoriteApatiteOrthoclase (Feldspar)QuartsTopazCorundumDiamond(hardest) Thus minerals 1-6 can not scratch quartz.
Glass has hardness of about 5.5 which minerals will scratch it?
feldspar, quartz, topaz, corundum, diamond.... Diamond will diffidently scratch glass its also made to cut glass if you get tech with it. (alyssamc6)
What is formed when Quartz and Feldspar are mixed together in nature?
Quartz and feldspar are commonly found together in granite and gneiss.

Can calcite scratch feldspar?
no
