Antiquing Gold
--
Does any one have any information on an environmentally safe/friendly solution to antique and/or blacken gold for an antique appearance? Would like to relieve and polish the gold after antiquing.

Bill,
As gold is very inert to oxidation the only method I know is to plate a thin coat of black nickel or "Electroblack" an Enequist (I think from NY) then relieve. Hope this helps.

Bob:
Thanks for the response. We used to use Electroblack but removed it from our plant because of the hazardous chemicals. The latest Gesswein catalog has a product called
- Oxaul Salts
which says it blackens gold.
Has anyone out there ever tried it? Is it safe to use? What about disposal? Thanks for your help.
Bill Christiansen--
Do you guys know what chemicals are used to antique copper and brass?
Thanks, Bill.

I have a 14K gold ring that has been processed with this blacked effect. I wanted to know if it is possible to reverse this process? this ring has alot of diamonds in it which were set upside down...quite unusual.
