How about we stick your 'water' bonded pieces of glass in my Vacuum
chamber. If the bonding is molecular, the two pieces will stay stuck
together.  If its only a physical bond do to Air pressure forcing the pits
to lock together like velcro, then the two pieces should easily seperate in
a vacuum.   (I've been wanting to test this for a while now anyway :)
