Hi All! Is there anyone on this list who has an in depth knowledge of ancient Egyptian fayience? I am working on a piece of fayience that had a cartouche "erased", and I would like to know if there is any non-destructive process that might enable me to find a latent image of what had been erased. The item is a fragment of an uaz, probably 6 to 8 inches long, when intact. It dates to the reign of Amenhotep III. Thanks. Russ
