Ice forms numerous phases at high pressures that are denser than liquid water. Exploring the phase diagram has been an ongoing process, and success has often been obtained by finding a method or trick to accelerate the transformation from one phase, in which it may be trapped, into another. Salzmann et al. (p. 1758) show that the addition of hydrochloric acid to two disordered phases of ice, ice V and ice VII, could unlock their geometrical frustration to form two previously uncharacterized phases, ice XIII and ice XIV.
