Technical Terms
What is Vermeil?
Vermeil is a French
word long used to designate a silver, bronze or coppery object plated with
gold. Today the term is used in commerce simply to describe gold plating
on sterling silver. Gilding, the predecessor of plating, was introduced
in Europe during the Roman period and retained its importance until the
introduction of electro-plating in the mid-19th century.
What is gold-plated?
Also referred to as electroplating. A solution containing gold particles
and disodium phosphate (the electrolyte) is placed in a metal tank. This
tank becomes the anode (or negative). The item to be plated is suspended
from a rod and becomes the cathode (positive). The rod is put in the solution.
So now we have a positive, a negative and the electrolyte all together.
A charge of electric current passes thru the solution creating an ionic
exchange and the gold particles pass from the solution to the item and it
is gold.
What is gold-filled?
A thin layer of 12kt or 14kt gold is fused
and soldered to a base metal, usually brass. 1/20 of the total weight of
the metal is real karat gold. What actually comes in contact with the skin
is karat gold.
What is Sterling Silver?
An alloy of 92.5% pure silver and
usually 7.5% copper. Pure silver is too soft for most uses and needs to
be combined with another metal. It is the copper in sterling that causes
it to tarnish.
What is Argentium™ Sterling Silver?
The word argentum was
used in the ancient world to refer to silver. Argentium™ today is a relatively
new type of sterling silver alloy that is highly tarnish resistant, harder and more durable than regular sterling. Argentium™ is still sterling,
having at least 92.5 pure silver. It is the other 7.5% that has been changed.
We use Argentium™ wherever we can. See below. Clean Argentium™ as you would
sterling silver.
