diamonds you idiot, even guys can answer that !
A harder mineral will scratch a softer one.
it is hardness
Diamond is the hardest mineral and is the only one that can scratch corundum. but in my opinion corundum will scratch corundum any mineral of the same hardness will scratch the other !
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
false a mineral can not scratch any mineral harder than itself
Corundum can scratch almost any mineral that isn't diamond.
the softer mineral can be scratched by a harder mineral. Ex: talc is 1 and quartz is 7 so quartz can scratch talc
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.
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.
You can tell what Topaz can scratch by looking at the Moh's Scale of Hardness. It looks at ten well known, easily available minerals, and arranged them in order of their "scratch hardness". If a specimen to be tested can be scratched by a known mineral from the list, it is softer than that mineral. If it in turn will scratch another known mineral, it is harder than that mineral. Topaz is ranked an 8 and therefore can scratch everything lower than an 8. This includes quartz, feldspar, apatite, calcite, gypsum and talc.
dimonds is hard enough to scratch anything.
the real color inside a mineral. you scratch the mineral on a tile
