Great experiments and very pleasing effect Ian.

Try using a 1% or 2% sodium bicarbonate solution as a bleach. May take a bit longer but could be less aggressive.

I plan on trying some toning with tannic acid (basically your tea & coffee!) and also lead acetate (violet). Need to make the lead acetate though...
