Cyanide-free gold plating solutions

1998

I would like to know of a GOOD cyanide-free gold, I have used cyanide gold in the past, and besides being illegal and making me woozy feeling, its has worked wonders and made me hundreds. I want to gold plate legally, and safety is still a concern even though I now use an air supply system, that I bought for car painting. I am using a gold fx system and I will need a gold that can withstand high current.

I would very much like a recipe for an acid base solution, just like the Cyanide solution, if anyone has a good one, I would love to see it.

I was wondering if anyone had a good recipe for cyanide free/sulphite gold bath solution, in detail for, if you do it will be very much appreciated.

Thanx
