gols plating solution gone bad??????

[guymark]

Did any joy ever come of this?

I have done some research and I think I know the ingredients now, an am guessing that either sodium phosphate and/or sodium sulphite may be required to re-activate it.

1 gm gold chloride
75 gm sodium phosphate
2,5 gm sodium sulphite
1 litre de-ionised water

From fresh, this basically makes a workable solution, but not a very stable one - which means after a few months it needs to be perked back up - I just haven't yet worked out how it is duly perked.

It would be nice to find out what we need to do - I have a litre of the stuff that cost me about £60 IIRC.
