HOW TO REMOVE SOLDER-GOLD AND LEAD-FROM GOLD JEWELRY

Hi, Jill. It's readily available from jewelry supply companies, but they can be reluctant to sell it to people who don't have some kind of certification and an actual jewelry store (outside of the home) because of the liability of product stewardship. It's dangerous toxic stuff, and moreover a very powerful oxidizing agent that can set paper on fire. I had a friend who tried to sop up a spill with newspaper and almost set his shop on fire -- had it been a house rather than a high-ceilinged concrete and steel factory, he certainly would have.

Hello, can anyone give a specific recipe for this mixture? And have you actually used it to remove lead from a non Ferrous alloy? I want to remove solder form silver/copper alloys
Please let me know your experiences. Thanks, Pete

What is the mixture of nitric acid and Hydrogen Peroxide would one use to remove Lead Solder From Silver?

Hi
I used a mixture of (50-50) hydrogen peroxide, or blonde hair dye and photochem econostop, the stuff photographers use, basically it's acetic acid, and it removes lead from gold.
