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 is softer than the topaz but the topaz is softer than diamonds which are the hardest :) hope this helps
Hardness
apatite will not scratch quartz topaz calcite or corundum
yes no, it doesnt Topaz is harder than qartz
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
There are many different kinds of glass, with different hardnesses, but for the most part the hardness of quartz can be taken as a maximum value. Topaz will in fact scratch quartz, so it should scratch nearly any kind of glass.
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
apatite will not scratch quartz topaz calcite or corundum
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.
According to the Mohs scale of hardness, Diamond has a hardness of 10 and Quartz has a hardness of 7. Any mineral with a hardness greater than 7 can scratch quartz and diamond can scratch any mineral with a hardness less than 10. Corundum (hardness of 9) and Topaz (hardness of 8) are two examples of minerals that can scratch quartz but not diamond.
Any mineral with a Mohs hardness of 7 or greater could scratch quartz. Examples would be quartz (7), topaz (Mohs 8), corundum (9), and diamond (10).
Topaz is very much like quartz. They both can be found naturally in any color. They're both harder than glass. Topaz is, however, a little bit harder than quartz and will scratch quartz.
yes no, it doesnt Topaz is harder than qartz
nothing

There is no mineral that would satisfy the question. If a mineral is able to scratch feldspar, it would have a Mohs hardness of 6 or above. Fluorite is rated as a 4. It would be impossible for a mineral which scratches feldspar to be unable to scratch fluorite.
The Mohs scale of mineral hardness is purely ordinal, meaning it does not rely any relative difference in values. Using a sclerometer, it will take twice as much force to create the same scratch in topaz as quartz.
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.
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
