One tip.This last batch and previously processed antique flatware the solution was also green.
So after cementing out the solution with copper pipe the solution had changed to a coil alt blue that I associate with copper nitrate.
Using reactivity scale everything below copper cements out right?
So if it was Nickel it would have stay in solution and wouldn’t the have stayed green?
That cemented silver didn’t melt very well either .
I thought HCl and H2O2 didn’t react with silver and would dissolve Pd that why I chose to go that route.
My Intent was to remove copper and potentially Pd from the cemented silver and use the silver cement to make a new electrolyte for another go a silver cell.
When you reply to a post, especially when the threads get long, is to reply to the actual post, not the entire thread.
Then it is easier to understand which post you refer to, this time it is easy, some times not.
I see the drift, sometimes old Silverware can contain Pd that is true, but that will be caught in the slimes in the Cell.
It should not be enough to influence the melting point much at all, so I guess something else is influencing your melt.
If you melt it as anodes, copper should not be of concern, nor the potential Pd, since it will report to the slimes.
Pd Nitrate has a strong maroon color so it may indeed be the culprit making your Copper Nitrate green.
For electrolyte, I would use my my fresh crystals from the last run.
