I have recently started using Tarnish free silver or Germanium silver
or = “Bright sterling silver” as it is being marketed. It is a little
softer = when annealed than standard sterling silver but hardens up
nicely after = working. It is not fully understood yet but it is also
reputed to harden after an hour or so in a very hot domestic oven. I
have not tried this myself so I can not yet comment.
As to the US food and drug standards, who knows what they might
decide. I know that the silver is undergoing tests for ISO 8442
certification, which is an internationally recognised standard for
materials safety. It is interesting to note that there is alot of
scaremongering with regard to germanium, perhaps it is something to
do with how the name sounds…a little to much like Uranium or Germ or
a certain well known plant.
Germanium is commonly found in many day to day materials. In Japan
they use it in the production of P.E.T. bottles for mineral water and
coke. They use Germanium because they absolutely ban the use of
Antimony trioxide which has been found to leach into the contents of
western produced bottles. Germanium is found in American Oats,
Korean Ginsing, Baked beans and in Tined tuna at 3 ppm. The Korean
ginsings germanium content is actively promoted. It is also known in
Japan as a health suppliment. The water at Lourds is reputed to have
a germanium content and it’s also present in polyester and Gold
dental alloys in order to harden them.
In Data taken from the Health and Safety Document EH40/98 (UK)
regarding Occupational exposure limits Silver is 6 times more likely
to kill you than germanium.
Eagle Pitcher is the US company that has been involved with Germanium
since the start and they have nothing to report regarding toxic
effects of Germanium in it’s pure form.
However I understand that the Germanium Compound GE0 132 has been
banned in the US but as this is a compound and not a metal it has no
bearing on the subject of the Germanium content of the bright silver
In short…I guess it’s here to stay and coming your way soon. I love
the thought that I will most likely never have to buy a cyanide
stripping unit and worry that my silver jewellery will tarnish in the
shop window before it is ever sold.
