What else can I help you with?
Can talc scratch feldspar?
No, talc is softer than feldspar on the Mohs scale of mineral hardness. Talc has a hardness of 1 while feldspar has a hardness of 6-6.5, which means that feldspar is resistant to being scratched by talc.
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.
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.
A mineral with a hardness of 6?
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
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.
Can talc scratch feldspar?
No, talc is softer than feldspar on the Mohs scale of mineral hardness. Talc has a hardness of 1 while feldspar has a hardness of 6-6.5, which means that feldspar is resistant to being scratched by talc.
What object can scratch apetite but not feldspar?
The object that can scratch appetite but not feldspar is quartz. Quartz has a hardness of 7 on the Mohs scale, while feldspar has a hardness of 6. Therefore, quartz can scratch appetite, which has a hardness of about 5.5, but cannot scratch feldspar.
Would feldspar be use to test mineral hardness?
Yes "feldspar" is one of the minerals on Moh's scale of hardness.
What mineral is harder fluorite or feldspar?
Feldspar is harder than fluorite on the Mohs scale of mineral hardness. Feldspar has a hardness of about 6 to 6.5, while fluorite has a hardness of 4. This means that feldspar can scratch fluorite, making it the harder of the two minerals.
Which object can scratch feldspar but not quartz?
