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
The two major types of minerals are what?
Two examples are quartz and mica. Minerals are also classified as metallic or non-metallic.
What is quartz fluorescence?
Fluorescence occurs when a substance has absorbed light and later emits that light. Quartz is a material that undergoes this process. Minerals and creatures can both exhibit fluorescence.
What causes the different colors of quartz?
Trace amounts of other minerals in the crystalline structure of the SiO4.
What is an example of quartz?
Amethyst, rose, citrine, smoky, etc., are all examples of quartz. Few minerals come in such an amazing array of colors and crystal habits!
Which minerals will not scratch quartz?
fluorite ,tale ,gypsum
What two minerals are harder than calcite but softer than quartz?
the minerals are fluorite, apatite ,and orthoclase
Which minerals on Mohs' hardness scale can be scratched by quartz?
Othoclase, apatite, fluorite, calcite, gypsum, and talc.
What are 8 examples of minerals?
Diamond, graphite, quartz, topaz, calcite, fluorite, dolomite, magnetite, hematite, pyrite...
What can scratch fluorite?
quartz
Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
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.
Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
What minerals can scrach glass with a hardness of 5.5?
# Talk # Gypsum # Calcite # Fluorite # Apatite # Feldspar # Quartz # Tourmaline # Corundum # Diamond This is Mohs scale of hardness with diamond being the hardest. Therefore minerals 6-10 will scratch a glass of hardness 5.5
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).
Can calcite scratch other minerals if so which one?
No.because calcite is softer then feldspar
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.
