Dear Gayle,

It has been known for many years that if something gets chipped or a =
handle gets knocked of that it can be re-attached or repaired by =
dampening the fracture faces freely with Vinegar and pressing the parts =
together. Though this has never been explained by those who publish =
these instructions I believe there are two things happening.

The first is that once the surfaces are wet then the slurry from both is =
deflocculated in the same way that the strong alkalies deflocculate, but =
the charge is positive instead of negative.

The second thing is that the Acetic acid in the vinegar does not dry by =
evaporation as does water. It will, in fact, solidify below about 16 deg =
C and crystallise as water evaporates, so forming a solid bond between =
parts which are being joined.

Nothing magic about the process.
