Feldspars generally have a hardness of 6 on Mohs' hardness scale.
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.
Orthoclase Feldspar.
The mineral that can scratch feldspar and can be scratched by garnet is quartz. Quartz has a hardness of 7 on the Mohs scale, making it capable of scratching feldspar, which has a hardness of 6. Meanwhile, garnet has a hardness of around 6.5 to 7.5, allowing it to scratch quartz but not all varieties of garnet will scratch quartz.
If you rub a piece of fluorite against a piece of feldspar, you would likely observe that the fluorite leaves a streak on the feldspar due to its lower hardness on the Mohs scale. Fluorite has a hardness of 4, while feldspar ranges from 6 to 6.5, meaning feldspar is harder and would not be scratched by fluorite. The interaction may produce some fine dust from the fluorite, but it would not result in significant abrasion of the feldspar.
Feldspar can be found in many things, including soap
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.
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.
Yes "feldspar" is one of the minerals on Moh's scale of hardness.
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.
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.
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.
No on the mohs scale the fingermail is lower than feldspar. Source:Knowledge.
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
Feldspars generally have a hardness of 6 on Mohs' hardness scale.
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.
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
