I think this is a false analogy. The mechanism is a very long soak in
water. The gum isn't *soluble* and the long soak doesn't make it soluble,
but softens it so that it becomes *abradable* -- in the same way that
tempera or watercolor paint on a perfectly fine and archival painting
could be softened and become abradable after a long soak in water.
