II. Surface-layer Enrichment by Addition Mercury amalgams were used for plating the metal- surfaces, i.e., gilding or silvering, before the invention of electroplating. Molten amalgam of gold and mercury (or silver and mercury) is smeared on the cleansed metal surface. On heating, mercury gets volatilised and a thin layer of gold or silver is obtained on the surface of the metal. The descriptions of this kind of amalgamation gilding are found in Slokas 150, 720, 600-602. 21 One masa ball of mercury (mrtgolaka) and
one māsa ball of killed gold are to be rubbed,
with citric acid for three days. The leaves of
one "karsa" of lead, smeared with this paste of
gold and mercury kept in a closed crucible when
roasted becomes gold. It (gold) is to be taken
out when it cools down by itself. The gold thus
produced, is to be collected to attain success
in the pursuit of Dharma, Artha, and Kāma.
