Electrofreezing experiments of super‐cooled water with different ions were performed on the charged hemihedral faces of pyroelectric LiTaO 3 and AgI crystals. In their Communication on page 15575,D. Harries, M. Lahav, I. Lubomirsky et al. demonstrate that HCO 3 − ions elevate the icing temperature near the positively charged faces, whereas H 3 O + slightly reduces the icing temperature.
