Hi there!
I just melted some scrap silver to do some broom casting and it
turned completely copper colour in the pickle. I tried soaking with
peroxide and it has not helped. Is there any way to salvage the
silver without refining?
Thanks
Gerry
Jerry that happens to me alot with drop casting from scrap. I just
anneal and change the pickle and go from there even in fresh pickle i
get some residues but they wipe off with an auto polishing cotton
towel its neon yellow and I get them by the package at costco.
They polish silver, remove stains without scratching and they clean
my hands! lol
wet dry they are stupendous

Sounds as though the pickle was contaminated or your scrap silver
contained some ferrous metal that you weren’t aware of…
Gerry, I suspect that you need to add some sodium bisulphate (=Ph
Down, or Sparex) to the peroxide, before soaking your melted slver
scrap, in order to remove its copper color. When tiny, tiny bubbles
start to come up, off the surface of the metal, you have got the
right amount of both chemicals.
