In an attempt to characterize the nature of the glass transition in vitreous water we have vapor deposited the amorphous solid directly in a differential scanning pan, and studied its warm-up behavior under high-sensitivity conditions. Notwithstanding the use of many preparation variations and DSC scanning cycles known to maximize the thermal manifestation of the "glass transition", no transition anywhere in the region expected from binary solution extrapolations has been detected. Rather, the material remains unrelaxed up to the onset of crystallization commencing abruptly in the range 150-162 K depending on deposition conditions. We interpret the observation by reference to known (network glass + "modifier") system behavior.
