Low temperature magnetization measurements on the pyrochlore spin ice compound [Formula presented] reveal that the ice-rule breaking spin flip, appearing at [Formula presented] applied parallel to the [111] direction, turns into a novel first-order transition for [Formula presented] which is most probably of a liquid-gas type. [Formula presented]-linear variation of the critical field observed down to 0.03 K suggests the unusual situation that the entropy release across the transition remains finite [[Formula presented]] as [Formula presented], in accordance with a breaking of the macroscopic degeneracy in the intermediate “kagomé ice” state.
