The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
A mineral with a hardness of 6 on the Mohs scale can be scratched by anything harder than a 6, such as minerals with a hardness of 7 or higher. It will not be scratched by minerals with a hardness of 5 or lower.
apatite, cobalt, zirconium, palladium, tooth enamel, obsidian (volcanic glass)
It can be scratched by a diamond, corundum, topaz, and quartz.
apatite with a steel knife feldspar with window glass
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.
The mineral that can be scratched by glass but not a penny is calcite. Calcite has a hardness of 3 on the Mohs scale, which is lower than the hardness of glass (5.5) but higher than that of a penny (2.5).

window glass
Diamond is the hardest mineral that can scratch a steel knife or window glass.
Glass window use a single edge razor blade.
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
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.
