75‐ml samples of de‐ionized, distilled water were frozen and electric potential differences between similar electrodes in the ice and water respectively were measured as functions of time, rate of freezing and temperature differences within the ice layer. The charge separation at the ice/water interface caused by selective rejection of ions always exceeded that due to temperature gradients within the ice at freezing rates greater than 10 μm s −1 .
