Glauberite is a sodium calcium sulfate mineral with the formula Na2Ca(SO4)2, which forms as an evaporite. It is named for the closely related Glauber's salts. Because of its solubility, glauberite is often dissolved away from the crystal matrix leaving a mould into which other minerals are deposited giving them an anomalous crystal form.
