Stripping off silver plate from pewter

A. You can strip it electrolytically. This is safe and simple way. 2% solution of silver nitrate may be used as electrolyte (1 lit water, 20 gm silver nitrate, you can add few drops of nitric acid).Your object =anode(+),piece of SS= cathode(-). As current source you can use hobby drill transformer,but only for small scale work (up to 6 dm2).

Good luck!

A. Goran's advice is appreciated, but maybe you should take this to a plating shop, Martin. You'll probably find copper under the silver and have strip the copper. Both silver and copper are powerful biocides, so you shouldn't dump the stripping chemicals. And I would not be shocked to find nickel in the plating sequence either. If you do chemically strip it, you may want to remove any remnants by buffing them away; but the plating is probably too thick and extensive to buff it all away without chemical stripping.

Remember that the silver plating is food safe, whereas antique pewter may contain toxic lead. Good luck.
