This was manufactured some years ago (1980s) by a firm called
Sheffco. and it uses a chemical electro-deposition method of
depositing silver on suitable clean metal surfaces.  You can also
build up layers but each layer is extremely thin so that after 25
applications you will only have a layer about 0.3 microns thick!
Once it tarnishes and is cleaned with a rouge-based silver polish
the layer is often partly or totally removed and needs

Whether its chemical technology has advanced since I used it I am
not sure.
