What can talc scratch?
Talc can scratch Talc , although Talc's hardness varies it is considered a soft mineral, that can even be scratched with a finger nail. Any mineral or material with a hardness equal to or greater than 1 on the Mohs hardness scale will be able to scratch talc. Talc is the softest mineral listed on the Mohs scale, listed as a 1 on the scale which is graded from 1 through 10, with 10 being the hardest (diamond).
What is feldpars hardness?
Orthoclase comes in as 6 on Mohs scale of mineral hardness:- Talc, Gypsum, Calcite, Fluorite, Apatite, Orthoclase, Quartz, Topaz, Corundum, Diamond;
Can amber scratch talc but not calcite?
Yes
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.
Can calcite scratch other minerals if so which one?
No.because calcite is softer then feldspar
What mineral can scratch talc but is not scratched by calcite?
Gypsum
Can a fingernail scratch a talc?
Talc i assigned a hardness of 1 according to the Mohs scale of hardness. This implies that talc has the least hardness and therefore is soft and can be scratched by a fingernail.

Which is the hardest mineral out of calcite talc fluorite and quartz?
Quartz- hardness 7 on Mohs Scale. (Calcite: 3, galena 2.5, talc 1)
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 talc scratch feldspar?
According to Mohs' Hardness Scale, talc registers at a 1, whilst feldspar registers at a 6, so, no, talc cannot scratch feldspar.
Which minerals on Mohs' hardness scale can be scratched by quartz?
Othoclase, apatite, fluorite, calcite, gypsum, and talc.
What mineral you can scratch with your fingernail?
The most commonly known mineral that can be scratched with a fingernail is talc.
How do you determine how soft a mineral is?
The hardness of a mineral is categorized on the Mohs hardness scale with talc as 1 and diamond as 10. A mineral can only be scratched bya mineral that is as hard or harder than the first mineral. So talc can scratch talc but nothing else. A diamond can scratch every other mienral including itself. Cordundum with a hardness of 9 can't scratch diamonds but can scratch a lot of other minderals.
