Diamond is the hardest mineral that can scratch a steel knife or window glass.
What mineral will scratch with a window glass or a knife blade?
A mineral that will scratch with a window glass but not with a knife blade is a mineral with a hardness between 5.5 and 6.5 on the Mohs scale, such as orthoclase or peridot.
What mineral can be scratched by a steel knife but not a copper penny?
Copper. Copper has a hardness of 2.5-3 on the Mohs scale, while a steel knife generally has a hardness of around 5.5 - 6.5. This means that a steel knife can scratch copper, but a copper penny cannot scratch a steel knife.
What test can help distinguisg gypsum and quartz?
The scratch test can help distinguish gypsum from quartz. Gypsum is a soft mineral, so it can be easily scratched with a fingernail or with a knife blade. Quartz, on the other hand, is much harder and cannot be scratched with a knife blade.

Can the mineral azurite scratch glass?
apatite can not scratch glass. it is considered number 5 1/2 on the Mohs Scale Of Hardness. Apatite is number 5 on the scale and can only scratch itself and all of the minerals lower on the scale.

Is quarts mineral?
Quartz is a mineral. It has a hardness of 7 on Mohs Scale of Hardness; thus, it scratches glass but it is not scratched by a masonry nail or knife blade. It does not have any cleavage, it only fractures, and it can have conchoidal fracture (similar to glass). It is also a light-colored nonmetallic mineral with a greasy luster. It can be colorless, white, gray, or other colors. Other distinctive mineral proprieties include its hexagonal prisms, pyramidal structure, and that it can be transparent or translucent.

If a mineral can be scratched by a fingernail but not by a pocket knife what does that tell us about the mineral?
It would have a Mohs hardness somewhere between 2.5 and 5.5.
If a knife blade scratches the surface of a mineral that mineral is considered hard?
Most knives have a rockwell hardness of 54-62. this is for metals. minerals are considered ceramics and therefore should have more hardness. It really depends ont he pressure applied. With enogh pressure any knife can scratch any mineral.
