Testing purity of silver
I work for a freight salvage business and we have received a container (about 50 lbs) of what we were told is silver. I took it to a jeweler and they confirmed that it is indeed silver. However it is in misc. pieces that look as if it is the waste material of a manufacturing process. We do not know the origin of this silver. The jeweler offered us about 70% of the market value of silver.
Is there a way to test for the purity of this silver or to test what other alloys might be in this silver? Also if it is not pure how do we assess the value and/or how do we have it reclaimed or find out if it is worthwhile to do so?

Hi, folks. Sorry that many of these questions remain unanswered. We hope that a knowledgeable reader will answer, but we can't force them :-)
Perhaps if the questions would take into account the effort that a responder has already put in, instead of starting from the top again, and if they were cast in a compelling personalized way, there might be a better response.

Q. What could cause a well calibrated XRF gun to test 100% positive for Ag; scratch stone creamy, yet too hard to be silver? I have a fork no markings or hallmarks. Its testing positive with 18K jsp solution for silver. Ground in deep, still same reactions. Had it tested with a well calibrated Niton XRF and testing 100% Ag. how is this possible. There is no such thing as a 100% solid silver fork is there? I've been a scrapper for years and this is the first I've ever come across this. everything else is testing right sterling is testing right around 92.7- 94.6 yet this fork no markings 100% and passing nitric acid? what the heck please advise..R Fabiano
