Sorry to break it to you but this is not densities but molar masses.Thanks man....,however I'm actually excited about the tests and information I'm given.
It seems - and I hate to say this - but sense I'm a sigma empath, I know damn well whats going on in the minds when engaging with people. And it doesn't help that Seattle got rated #1 sadest city in America. Which I knew before the new poll came out.
Point is, after passing XRf, acid, and even a density scale tests, plus having a Pallidium hallmark on 1 item, the LCS' or gold buying companies here not only just say no, but start yelling and screaming in public in front of people. They are liars, thiefs and highly racist and discriminative. And if your'e good looking, black, brown, in shape, have a good attitude, you're totally fu#ked as soon as you walk in. I'm a little buzzed, bare with my rant. So when I came here I thought this site seemed not at all biased. But then I'm reading flat out lies about stuff. People get passionate and excited in life about things, especially a hobby/business like this. But like my coin collecting days, the people in charge ruined my favorite hobby. But anyway thats that...I know all over the place. But check these out.
Mass/Density numbers are in the middle. Move a decimal over 1 to left.
Look at Gold and Silver - they are correct densities +/- .2 grams
And stop ranting about lies, most people do a white lie from time to time, but they are honest almost all the time.
Your assumed Pd item do not make sense, it could have been, if it was not Silver plated, but why plate with a less noble metal?
Are you sure it is not a Silver item with Rh plating, they do exist.
To me it seems you need to study more so here are some material for you.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: Screen Readable Copy of Hoke's Book
2. Then read the safety section of the forum: Safety
3. And then read about "Dealing with waste" in the forum: Dealing with Waste
Suggested reading: The Library
