minimum millesimal fineness of
925. Sterling is an alloy of silver
containing 92.5 % pure silver and
7.5 per cent other metals, usually
copper.
Fine silver (99.9% pure) is
generally too soft for producing
large functional objects, therefore
the silver is usually alloyed with
copper to give it strength, while at
the same time preserving the
ductility and beauty of the precious
metal. Other metals can replace
the copper, usually with the intent
to improve various properties of
the basic sterling alloy such as
reducing casting porosity,
eliminating firescale, and
increasing resistance to tarnish.
These replacement metals
include germanium, zinc and
platinum, as well as a variety of
other additives, including silicon
and boron. A number of alloys
have appeared in recent years,
formulated to lessen firescale or
to inhibit tarnish, and this has
sparked heavy competition among
the various manufacturers, who
are rushing to make claims of
having the best formulation.
However, no one alloy has
emerged to replace copper as the
industry standard, and alloy
development is a very active area.
