Desalination

We need to desalinate archeological pottery (Tairona-Colombia) and
the objects have black pigments on the entire surface or a black
finish related to its technology; nevertheless this is soluble in
water.

We are thinking of protecting it by consolidating with paraloid B72
at a really low concentration, and after that desalinating by using
wet paper soaked with deionized water. If there are any suggestions
on this process or another way of eliminating the soluble salts, it
would be of great help.
