Chemical Polish of Jewelry with Thiourea

Hello,

I am a student and I am searching information about a Chemical Process of polish of jewelry with Thiourea ⇦ this on eBay or Amazon [affil links] (in replace of Cyanide).

So what have you learned about it to date, Carlos?

I've seen and heard of cyanide-peroxide "bombing" for chemical polishing (there are several threads on this site about it), and I'd like to hear of a Thiourea ⇦ this on eBay or Amazon [affil links] alternative myself. Thanks.

Carlos,

Thiourea is a mutagen, be careful.

Hello again.

Ted, right now I don't have any information about the Chemical Polish of gold and silver with Thiourea, so any information that I can get will be very useful for me.

Thanks for your answer.
