No, they are two different minerals.
Talc is a very soft mineral, unlike quartz, and so is less likely to be abrasive.
Examples: coal, talc, quartz, magnetite, copper etc.
Quartx is and example of a mineral that is a chemical compound it is made of the silicon and oxygen
Talc has a mineral structure that makes it very brittle all the way down to the molecular level - it only needs a touch to break and so it is considered a 'soft' mineral because it is so weak and breaks so easily.
the thing that makes quartz uniqe is the colouring and the size.
Quartz- hardness 7 on Mohs Scale. (Calcite: 3, galena 2.5, talc 1)

yes
igneous rocks
the softer mineral can be scratched by a harder mineral. Ex: talc is 1 and quartz is 7 so quartz can scratch talc
A base has a slippery soapy feel.
Quartz powder is dangerous to the respiratory system.
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.
Talc Diamond Quartz
schist
Examples: coal, talc, quartz, magnetite, copper etc.
No, smoky quartz and moonstone are not the same thing. Smoky quartz is a silicon dioxide crystal while moonstone is a sodium potassium aluminium silicate.
