General description
Sodium sulfate decahydrate (Glauber′s salt, mirabilite, Na2SO4·10H2O) is the decahydrate salt of sodium sulfate. Its crystal structure has been investigated by single-crystal neutron diffraction studies. Its crystallization enthalpy has been evaluated. It can be synthesized by reacting MnSO4, thiophene-2,5-dicarboxylic acid and sodium glutamate.

Pressure exerted by crystallization of salts within porous materials contributes to damage in historic and modern construction. By unequivocally identifying the precipitating phase(s) while simultaneously determining solution supersaturation and associated crystallization pressure in subsurface pores, we show that the formation
