For what i am using this gold for i can't use the bleaching technique.
I don't think i was a clear as i should have been when i started this question. There are two liquid gold toners available in my area Berg and Fotospeed. I was not aware of the Tetenal version, so i was trying to come up with a similar formula that could be mixed in advanced and used on the run as one can with those specific toners. Quick easy and a one stop shopping adventure.
The other major gold toners we have on hand but result in something quite different than what i need for this particular application.
I did check in the Morgan and Morgan Guide, but no Dupont formula., but i did find the Ilford ones and might give them a try.
thanks to all.
