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.
Glass can scratch apatite but not feldspar.
On the Mohs mineral hardness scale, calcite is about a 3, and apatite is about a 5. So, whatever is at a hardness of 4 will scratch a 3 but not a 5. That mineral is fluorite.
apatite will not scratch quartz topaz calcite or corundum
bacially it has a hard harness.
Yes Apatite is a mineral.

Diamond is the hardest natural mineral, and will scratch glass, because glass is softer than diamond.
Probably not as apatite has a Mohs hardness of 5.0 and window glass lies between 5.0-6.0 on the Mohs scale. A higher Mohs number cannot be scratched by a lower number.
Diamond will scratch anything.
The statement is true. Apatite can indeed scratch calcite.
A few minerals that do not scratch glass come to mind . . . talc, asbestos, mica, for instance.
There is no such thing as an apatite rock but their is an apatite mineral
Any mineral with roughly a hardness of 6 or more on the Mohs scale of mineral hardness could scratch glass, which is roughly 5.5 on the Mohs scale. Some minerals that could scratch glass would be quartz, topaz, corundum, and diamond.
Minerals that will scratch apatite must be more than a 5 on the Moh's hardness scale. So feldspar, quartz, topaz, corundum, and diamond will scratch apatite.
No. The hardness of serpentine is 3-4.5, whereas a hardness of at least 7 is needed to scratch glass.
No it cant.
Diamond is a harder mineral than the minerals used to make glass.
Apatite is metallic.
