Doping with 10 mM HCl
- Ice-fourteen (ice XIV) is the proton-ordered form of ice-twelve, formed by doping with 10 mM HCl (about one molecule to every 5000 molecules of water; as DCl with D 2 O) below 118 K and at 1.2 GPa to facilitate the phase transition.

Ice XI is the hydrogen-ordered form of the ordinary form of ice. The total internal energy of ice XI is about one sixth lower than ice I h , so in principle it should naturally form when ice I h is cooled to below 72 K .
