Mostly 2 or 3. Halite and gypsum usually have a hardness of 2. Shale, sandstone, and conglomerate are about a 3. Limestone may eventually become somewhat harder as it morphs into marble, but may become quite soft if attacked by acids.

∙ 13y agoSandstone does not have a Mohs hardness. Mohs hardness is a relative measure of a mineral's ability to be scratched by another mineral. Sandstone is not a mineral or even a homogeneous substance, but a rock composed of various sand sized particles of rock or mineral grains that are cemented by a variety of mineral cements and is therefore not suitable for measurement on the Mohs scale.
