The locality probably owed its name to the mineral;[dubious discuss] the origin of the mineral name is obscure[4] (though see above). The two kinds are readily distinguished by their different hardnesses: gypsum alabaster (Mohs hardness 1.5 to 2) is so soft that a fingernail scratches it, while calcite (Mohs hardness 3) cannot be scratched in this way but yields to a knife. 2, pp. 27, no. 109, no.
