In a recent article (Phys Chem Minerals. https ://doi.org/10.1007/s0026 9-017-0922-1, 2018), analcime hydrothermally synthesized from a gel and then reheated was reported to have undergone a loss of symmetry to Ibca. We show that the reheated samples, reported as different, are identical to each other and actually tetragonal. The fact that the tetragonal axis was oriented along the a or b vector in the two reheated samples instead of the c vector as in the conventional setting seems to have been the cause of the misinterpretation of the diffraction pattern.
