Hi
Here is what happen i started with old central telephone contacts
dissolved in nitric acid in till no reaction at the bottom of the vessel was grey powder solution green tested for pd test color green.So my thought that i have dissolved both silver and Pd
Now the gray powder i grabbed a spoon full and made AR results from test was orange so my thought is pt .Washed the gray powder 5 times then dried it.
then i tried to melt this and there was a lot of smoke This is a picture of the results what i got what can the green stuff that looks like a resin be it crumbles very easy. there is silver color beads mixed in this.
it was only metal when i started with nitric this stuff is from the nitric not the AR.
