Qtz is a 7 on Mohs Hardness scale. So it can scratch itself or anything less on the scale. Just that simple.

∙ 12y agoThe Mohs scale of hardness is made so that a mineral that is higher on the scale then another mineral should be able to scratch that mineral.
Yes, Quarts is a quite hard mineral made from silica and oxygen (siO2). Quarts has hardness 7 on the Mohs scale of hardness. Fluorite (CaF2) is 4 on the same scale. Both those are defining minerals on this scale meaning they are compared other minerals to see weather they have hardness greater or less than 7 and 4, respectively.
The hardest material until recently was diamonds with a hardness of 10. Now scientists discovered some other carbon structures like Fulerens and Graphene that are even harder than diamonds.

∙ 14y agoYes, absolutely it does.
Also there are different glasses with different hardnesses. Obviously harder glass will scratch softer glass and glass with the same hardness will also scratch.

∙ 12y agoyes, I believe so. But if my theory is wrong, please check the web.
If quartz is harder than most minerals such as feldspar, then it can easily scratch it. Any other mineral less than feldspar can not scratch it.

∙ 11y agoyes.pretty much any gem can scratch glass.
Wiki User
∙ 11y agoyes, because quartz is known to be harder than most minerals, including calcite

Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
What mineral can scratch feldspar but not quartz?
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.
What is the difference between a quartz and calcite minerals?
The major differences between quartz and calcite are hardness and cleavage. Quartz is about twice as hard as calcite. Quartz has little or at least very seldom any sort of obvious cleavage, whereas calcite has excellent and very obvious rhombohedral cleavage.
What mineral that can scratch gypsum but cant scratch calcite?
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
Which is better for jewelry calcite or quartz?
Quartz because it is harder, more durable and more resistant to scratching than calcite.
Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Which material would you scratch the other quartz or calcite how do you know?
Quartz because its harder than calcite and the quartz in thicker.
Both calcite and quartz can be found as clear crystals what tests can be used to correctly identify them?
Quartz would scratch the calcite. Calcite would not scratch the quartz. Calcite will react with dilute hydrochloric acid. Quartz will not. Calcite will exhibit double refraction. Quartz will not. If the crystal forms are intact, quartz crystal may appear six sided with pyramidal terminations. If they are of equal size, the quartz will be heavier.
Considering physical properties how do quartz and calcite differ?
you use the scratch test
What mineral can scratch feldspar but not quartz?
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.
Can calcite scratch other minerals if so which one?
No.because calcite is softer then feldspar
What will scratch calcite?
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
Will the mineral topaz scratch quartz or will quartz scratch topaz Why?
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.
What minerals would scratch fluorite - talc quartz or calcite?
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
Would a steel file be able to scratch quartz?
yes
What minerals can scratch a penny?
calcite
