Silver-Plating by Frank R. Stockton

The precious metals are gold, silver, and platinum. They are so called because they are rare and costly. Platinum is the most rare, and is used only to a very moderate extent. Gold is more plentiful; and silver much more abundant, though sufficiently rare to be considered a precious metal.

We do not often hear of articles of table service of solid gold, though solid silver is comparatively common. But, with the help of electricity, skilled workmen are able to cover the cheaper metals with one or more coatings of gold or silver, and the articles thus treated, look like solid gold or silver.
