Liquid water and vitreous B$_2$O$_3$ are the endpoints of a continuous rangeof random networks in which hydrogen bonds gradually replace covalent bonds.Previous work has shown that glasses can be obtained by quenching in the range$x \le$ 0.50. We report the wide-angle x-ray scattering by the liquid phase inthe composition range from $x$ = 0.38 to $x$ = 1.00 (pure water) attemperatures just above the liquidus. The first sharp diffraction peak (FSDP)remains at an approximately constant position in the range from $0 \le x \le0.8$. Beyond this range, the position of the FSDP shifts linearly to higherangles. The relative concentration of the molecular species in the glasses andmelts were measured with micro-Raman spectroscopy. Small molecular species arefound for glasses and liquids with $x > 0.36$, determining the critical pointat which the sample ceases to be a single macromolecule. Molecular water ispresent in liquids with $x > 0.62$.
