ideas standard has a minimum
millesimal fineness of 925. Sterling is an alloy of silver
containing 92.5% pure silver and 7.5% other metals, usually
copper. silver

Fine silver (99.9% pure)

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
silver

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

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.

Origin of the alloy metal
Although there is much confusion over the origin of the word
"sterling", there is general agreement that the sterling alloy
originated in what is now continental Europe, and was being used for
commerce as early as the 12th century in the area of what is now
northern Germany. silver

Origin of the word "sterling", used to
refer to the silver alloy
The word "sterling", used in reference to the 0.925 grade of
silver, emerged in England by the 13th century. The terms "sterling"
and "pound sterling" acquired their meaning in more than a century,
and from convergent sources. There are three possible origins for
the word "sterling". Two originate from 12th and 13th century
coinage, and one is generally discounted. The word could have
derived from the Old English word "stiere", meaning "strong, firm,
immovable". silver

Starling theory, discounted
Although marks of birds have been used in some coins of Edward
the Confessor, sterling is not likely to have been derived from
starling, as the word for starling at the time was spelt stær. If
the coin had been named after the bird, it would have been called
starling. silver

Mint mark theory
The 1955 edition of the Oxford English Dictionary states that the
early Middle English name sterling was presumably descriptive
of small stars that were visible on early Norman pennies. (Old
English: steorling.) silver

"Easterling" theory
An alternative explanation put forth by Walter de Pinchebek circa
1300 is that sterling silver may have been known first as
"Easterling Silver". The term "Easterling Silver" is believed to
have been used to refer to the grade of silver that had originally
been used as the local currency in an area of Germany, known as "The
Easterling" silver
jewelry, sterling silver jewelry, gift ideas.
This "Easterling" area consisted of five towns in northern
Germany that banded together in the 12th century under the name
Hanseatic League. The Hanseatic League proceeded to engage in
considerable commerce with England. In payment for English cattle
and grain, the League used their local currency. This currency was
in the form of 92.5% silver coins. England soon learned that these
coins, which they referred to as "the coins of the Easterlings", silver
jewelry, sterling silver jewelry, gift ideas were of a
reliably high quality and hardness.
King Henry II set about to adopt the alloy as the standard for
English currency silver
jewelry, sterling silver jewelry, gift ideas. He recruited metal
refiners from The Easterling and put them to work making silver
coins for England. The silver these refiners produced came into
usage as currency by 1158 in the form of what are now known as
"Tealby Pennies", and was eventually adopted as a standard alloy
throughout England silver
jewelry, sterling silver jewelry, gift ideas . The original name
"Easterling Silver" later became known as simply "sterling silver"
silver
jewelry, sterling silver jewelry, gift ideas .
The original English silver penny silver
jewelry, sterling silver jewelry, gift ideas was 22½ troy
grains of fine silver (as pure as can readily be made). 22½ troy
grains is equivalent to 30 so called tower grains or one tower
pennyweight. When Henry II reformed the coinage, he based the new
coinage on the then international standard of the troy pound rather
than the pre-conquest English standard of the tower pound. A troy
pennyweight is 24 troy grains. To maintain the same amount of silver
(and thus the same value) in a coin that weighed more required less
silver. It required that the alloy be only 92½% pure.
Though coin weights and silver purity varied considerably
(reaching a low point before the reign of Elizabeth I, who
reinstated sterling silver coinage for the first time since the
early 14th century), the pound sterling was used as currency in
England from the 12th century until the middle of the 20th century.
Specifically this was in the silver coins of the British Empire:
Britain, British colonies, and some former British colonies. This
sterling coin silver is not to be confused with coin silver silver
jewelry, sterling silver jewelry, gift ideas.
Sterling silver, no longer used in circulating currency, is still
used for flatware, jewellery and plate, and is a grade of silver
respected for both relatively high purity and sufficient hardness to
form durable objects in daily use silver

A century of dining regalia: the silver
craze of 1840 to 1940
From about 1840 to somewhere around 1940
in the United States and Europe, sterling silver flatware became
de rigueur when setting a proper table. In fact, there was a
marked increase in the number of silver companies that emerged
during that period
silver
jewelry, sterling silver jewelry, gift ideas.
The height of the silver craze was during the 50-year period from
1870 to 1920. Flatware lines during this period sometimes included
up to 100 different types of pieces. In conjunction with this, the
dinner went from three courses to sometimes ten or more. silver
jewelry, sterling silver jewelry, gift ideas There was a
soup course, a salad course, a fruit course, a cheese course, an
antipasto course, a fish course, the main course and a pastry or
dessert course.
Individual eating implements often included forks (dinner fork,
place fork, salad fork, pastry fork, shrimp or cocktail fork),
spoons (teaspoon, coffee spoon, demitasse spoon, bouillon spoon,
gumbo soup spoon, iced tea spoon) and knives (dinner knife, place
knife, butter spreader, fruit knife, cheese knife). This was
especially true during the Victorian time period, when etiquette
dictated that nothing should be touched with one's fingers silver

Serving pieces were often elaborately decorated and pierced and
embellished with ivory, and could include any or all of the
following: carving knife and fork, salad knife and fork, cold meat
fork, punch ladle, soup ladle, gravy ladle, casserole serving spoon,
berry spoon, lasagna server, macaroni server, asparagus server,
cucumber server, tomato server, olive spoon, cheese scoop, fish
knife and fork, pastry server, petit four server, cake knife, bon
bon spoon, sugar sifter or caster and crumb remover with brush silver

Flatware sets were often accompanied by tea services, hot water
pots, chocolate pots, trays and salvers, goblets, demitasse cups and
saucers, liqueur cups, bouillon cups, egg cups, sterling plates,
napkin rings, water and wine pitchers and coasters, candelabra and
even elaborate centerpieces.
In fact, the craze with sterling even extended to business
(sterling page clips, mechanical pencils, letter openers, calling
card boxes, cigarette cases), to the boudoir (sterling dresser
trays, mirrors, hair and suit brushes, pill bottles, manicure sets,
shoehorns, perfume bottles, powder bottles, hair clips) and even to
children (cups, flatware, rattles, christening sets).
A number of factors converged to make sterling fall out of favor
around the time of World War II. The cost of labor rose (sterling
pieces were all still mostly hand-made, with only the basics being
done by machine). Only the wealthy could afford the large number of
servants required for fancy dining with ten courses. And changes in
aesthetics resulted in people desiring simpler dinnerware that was
easier to clean.
Hallmarks
Over the years, most countries in the world have developed their
own systems of hallmarking silver. The purpose of hallmark
application is manifold:
Miscellaneous
In addition to the uses of sterling silver mentioned above, there
are some little known uses of sterling:
- Medical instruments: Evidence of silver and/or
silver-alloy surgical and medical instruments has been found in
civilisations as early as Ur, Hellenistic-era Egypt and Rome, and
their use continued until largely replaced in Western countries in
the mid to late 20th century by cheaper, disposable plastic items.
Its natural malleability is an obvious physical advantage, but it
also exhibits medically-specific utility, including the fact that
it is naturally aseptic, and, in respect of modern medical
practices, it is resistant to antiseptics, heat sterilisation and
body fluids silver

- Musical instruments: Due to sterling silver having a
very special characteristic in sound resonance, some brasswind
instrument manufacturers use 92.5% sterling silver as the material
for making their instruments, including the flute and saxophones.
For example, some leading saxophone manufactuers such as Selmer
and Yanagisawa have crafted some of their saxophones from sterling
silver, which they believe will make the instruments more resonant
and colorful in timbre.
Tarnish and corrosion
As the purity of the silver decreases, the problem of corrosion
or tarnishing increases silver
jewelry, sterling silver jewelry, gift ideas.
Chemically, silver is not very reactive — it does not react with
oxygen or water at ordinary temperatures, so does not easily form a
silver oxide. However, the other metal in the alloy, usually copper,
may react with oxygen in the air silver
jewelry, sterling silver jewelry, gift ideas.
The black silver sulfide (Ag2S) is among the most
insoluble salts in aqueous solution, a property that is exploited
for separating silver ions from other positive ions.
Sodium chloride (NaCl) or common table salt is known to corrode
silver-copper alloy, typically seen in silver salt shakers where
corrosion appears around the holes in the top.
Several products have been developed for the purpose of
polishing silver that serve to remove sulfur from the metal without
damaging or warping it. Because harsh polishing and buffing can
permanently damage and devalue a piece of antique silver, valuable
items are typically hand-polished to preserve the unique patinas of
older pieces. Techniques such as wheel polishing, which are
typically performed by professional jewelers or silver repair
companies, are reserved for extreme tarnish or corrosion. See also
