A Gold Plate For Small Articles Without A Battery

Digest a small
fragment of gold with about ten times its weight of mercury until it is
dissolved, shake the amalgam together in a bottle, and after cleansing
the articles, coat them uniformly with the amalgam. Then expose them on
an iron tray heated to low redness for a few minutes. The mercury
volatilizes, leaving the gold attached as a thin coating to the
article. The heating should be done in a stove, so that the poisonous
mercurial fumes may pass up the chimney.
