Plaster adhesive

From: Margot McKay Wright <ant011>

We have in our collection a number of calcite and alabaster bowls
from Egypt.  They have been reconstructed using a white insoluble
adhesive which, when tested, gave positives for sulphate and
protein--a casein plaster? The repairs are unsightly and the
adhesive has been smeared over the surface of the bowls. Does anyone
know of a way of reversing this medium?  I think that the repairs
were carried out at some time in the last century.
