Q. My daughter lives in Germany, and owns a set of fine china she inherited from her grandmother, [that] was previously owned by me, the daughter of the grandmother. That establishes the fact that it is quite old. It is not bone china. Recently she called me and said the china has become moldy, under the glaze. She tried soaking it in straight bleach. It went away but came back. What can she do?
