I now have a beautiful silver serving dish! Thanks so much for your advice. The hot water did not disolve the glue but loosened it. Some I could peel rite off; the rest I worked off slowly by submerging in hot water a while then using nail polish remover on cotten balls.I waited to polish till all the glue was gone.
The glue did no harm at all. As a mater of fact, I discovered this mess 4 years ago when moving & had never unpacked it when we finished the move. At the time, one small area peeled off & amazingly enuff, that area which the glue had touched remained untarnished for 4 years.
Thanks again for your website & advice.
