I have not been able to find the exact melting point for DHO, but perhaps it does not matter all that much.... ... since in any situation where there is substantial DHO, a certain equilibrium proportion of D2O will form naturally, and that process itself is probably accentuated by the repeated freeze/thaw cycles. It would be interesting to harvest some of this ice and have it run through a spectrometer. Jones
