What mineral Cannot be scratched by a fingernail ...
Can rock salt be scratched with a fingernail? Rock salt is composed of the mineral halite which is sodium chloride, or NaCl. On the Mohs Hardness Scale of 1 to 10, rock salt is a 2.5, which means it is a very soft mineral that is approximately the same hardness as your fingernail. You can scratch salt with a copper penny, pocketknife or steel file.
