Hi Guys,

I thought I float this for your thoughts.

My friend has a 10th Century Viking ring... the real deal, not a
replica. After 10 centuries it's just starting to take on yellow hue.

I see modern silver rings that simply go black within a relatively short
time.

The explanation that was given to me was that the silver blackening is
due to modern suphides pretty much everywhere.

Your thoughts?



Regards Charles
