OK, you experts on everything under the sun, how about this? I have a couple of salad plates from the SS France, (now twice as valuable because of the present demolition of the great ship), one of which got put through the dish washer inadvertantly many years ago. The result was the common phenomenon of the paint starting to dissolve. Does anyone know how to stabilise this? I don't use the plate at all any more, because just washing in the sink makes the paint run. Any suggestions? Can I slap on another layer of glaze and put it in a kiln?
