Hi bill and everyone Namaste
If I remember correctly this stain may have been there before the
lady had bought the ring. Only in such an indistinguishable intensity
that neither me nor the lady have noticed it! But looking back, I do
have the feeling that it has started before she bought the ring.
There are no suppliers of alloyed gold in this part of India [as far
as I know…] There’s this wonderful family on one of the jewellers
streets that I buy my gold from, they usually mix the alloy for me as
they have a large charcoal furnace and the experience of a family
line. They do my refining as well.
It is possible that at times, the refining process they do, may not
remove some? impurities [this has happened before, resulting with an
alloy which was nearly unworkable.]
What can I do now to remove this stain from the ring in such a way
that it will not re-appear ?
In the past I did thought it works like a miniature spring of oozing
black stuff… and it would eventually exhaust itself. Will the heat
of soldering temp. help ?
The Pickle ?
The ultrasonic ?
Caustic soda ?
Other kind of chemical ?
Please help me with this one. Love & Light akash
