Inca Metalwork. The science of metallurgy was more advanced in Peru than anywhere
else in the Americas. Deep mining was practiced, as well as a kind of smelting to
remove metal from raw ore. Copper and tin were combined to produce bronze, which
made stronger weapons and tools. Metalworkers also knew about casting, soldering,
Deposition gilding and silvering were undertaken in the Northern and Central Andean
regions using an elaborate technique that left a thin layer of gold or silver on
the surface of a copper or bronze piece. The first step was to dissolve particles
of the noble metal in an aqueous solution also containing acidic mineral compounds;
the liquid was then neutralized by adding lime and the piece was submerged in the
resulting solution, where some of the precious metal was deposited on its surface.
This technique is also known as electrolytic replacement gilding. The result is a
thin, fragile layer of gold or silver that is heated to bond it to the surface of
the metal and then polished to enhance the luster of the finished piece.
