Amber is a fossilized tree resin that has a hardness of about 2 to 2.5 on the Mohs scale, while talc is the softest mineral at a hardness of 1, allowing amber to easily scratch it. In contrast, calcite has a hardness of 3, making it harder than amber, which is why amber cannot scratch calcite. This difference in hardness explains the scratching ability of amber in relation to these two minerals.
Yes
Diamond can scratch talc but is not scratched by calcite. Diamond is the hardest mineral on the Mohs scale, making it capable of scratching minerals with a lower hardness, like talc.
No.because calcite is softer then feldspar
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).
No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch 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.
A penny would scratch minerals with a lower hardness rating such as calcite, gypsum, or talc. Minerals like quartz or topaz would not be scratched by a penny because they are harder than the metal in a penny.
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).
A copper penny can scratch materials with a Mohs hardness of 2.5 or lower, such as gypsum, talc, and some plastics. It will not scratch harder materials like glass, steel, or most ceramics.
you can scratch talc becuase it is the softest mineral on the moth scale.
No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch calcite.
calcite
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
