If it’s fine silver hen there can be no cadmium in it.
Cadmium was added to silver up until the 70’s to make the silver
more malleable - typically it was added to silver used for spinning.
The problem was that polishers could easily ingest small mounts and
this made some guys very sick after 50 or more years of using it.
I remember when I was a kid buying my first supply of polishing
equipment and several of the older guys in the shop warning me to
"get out of this business now!"
