The majority of all silver in the world is produced in Mexico, Peru, Canada, USA and Australia.
The biggest manufacturer is Mexico, that produces approximately 15% of the world's production. In most cases the silver is mixed with other metals in order to make it strong and resistant,
normally 92,5% silver and 7,5% copper is used, and is referred as "Sterling silver". The metal becomes more corrosion-resistant from air, water and other basic and sour materials.
The silver gets a darker and yellowish tone, in extreme cases the reaction becomes so strong that the metal gets dark. Silver often reacts with sulphur in the air and proteins that exist in the human body.
That means that silver must be maintained at regular intervals in order to retain its lustre. Silver that is produced nowadays most often contains no nickel, which
some people with allergies are sensitive against. The silver that comes from Mexico is free from nickel.
Silver is used in many processes in the industry, i.e. as a catalyst in developing photographs. It was detected already in the 19th century when the photo industy began. In connection with
the introduction of the the digital photo technology it decreased. The industry previously used about 60% of all silver, however the most part is nowadays used within the trade of jewelry.
A simpler and cheaper version of silver is silver-plated jewelry , which does not contain any silver at all. It's made of copper, zinc and nickel. Alpacka is another silver-plated alloy that contains a lot of nickel.
Both these alloys should not be used, if you have problems with nickel allergy.
When silver is converted to 925 sterling silver, it gets a more white tone that is referred to "925 silver" or as mentioned above; Sterling or Sterlingsilver. A new variant is 80% silver that is used in some parts of the world. |
