NaCl (table salt) is one of the few known substances in which crystalloluminescence occurs during crystallization. The crystalloluminescence can be explained by the luminescence of excited dopant cations in the crystal lattice of NaCl during the phase transformation from dissolved to solid, and not by triboluminescence of the crystals formed. It is assumed that the phase transformation also involves an energy conversion from potential to electronic energy, which leads to excitation of the contaminating ions; however, this is not chemiluminescence
