Hello all! Recently picked up a new hobby of smelting/refining and I have a question that I think you guys can help me with. I have been melting down silver and gold into bars, and I must have accidentally had copper or something else with some of the gold I had. Now when I use my testing kit on these couple bars it isn’t even 10k, would you recommend remelting these bars with more gold to try and get a readable karat? I ultimately want to refine the gold I have. Any suggestions would be appreciated. Thank you again and glad to have joined the forum.
