Prevention of silver tarnish
I need information related to prevention of silver jewelry from tarnishing either by adding some other less costly metal or by coating it with an invisible polymeric coating.Dr Padma S Vankar

Since you are from IIT, you can do some basic research.
Try this : Plate on an alloy of Silver and Germanium(about 1 to 5 % Germanium)- Marc De Bonte published a paper in 1993 on this.
After plating, heat for an hour ( about 120C ) ..This will solve the tarnishing problems.
