The effect of a sharp front separating the quark-gluon plasma phase from the hadronic phase is studied. Energy-momentum conservation and baryon number conservation constrain the possible temperature jump across the front. Assuming the temperature in the hadronic phase to be fixed from experiments one can determine the corresponding temperature in the plasma. In addition to the standard space-like discontinuities sudden transitions across a time-like front are also considered. The calculations reveal that the quark phase had to be expanded to a substantially supercooled state for a shock transition to happen. The supercooling is weaker if the hadronization occurs simultaneously across a time-like front than in the case of a space-like shock hadronization. If the initial phase is not pure but contains an admixture of hadronic matter slightly less supercooling is needed. {copyright} 1995 {ital American} {ital Institute} {ital of} {ital Physics}.
